*/
-cgnu // Notifies FlexeLint that gcc is being used.
// ===========================
// Preprocessor Configuration:
+fdi // GCC starts its #include search in the directory of the including
// file.
++fln // Allow:
// # digit-sequence " [s-char-sequence] " new-line
// as a synonym for:
// # line digit-sequence " [s-char-sequence] " new-line
// GCC additionally allows flag values to follow the
// s-char-sequence, but currently Lint ignores them.
-header(co-gcc.h) // Includes headers generated by GCC (bringing in
// predefined macros).
+libh(co-gcc.h) // Marks that header as library code.
gcc-include-path.lnt // This .lnt file should contain --i options
// and should be generated by invoking gcc with its '-v' option.
// (GCC's implicit #include search path is presented in the output.)
// This happens automatically when 'make -f co-gcc.mak' is invoked.
// Assertion directives (a feature of GCC's preprocessor) have been
// considered obsolete in GCC's documentation since version 3.0, so we do
// not use them here. If support for #assert is needed in the form of a
// lint option, one may use '-a#' like so:
// -a#machine(i386) // #assert's machine(i386) (SVR4 facility).
// File extensions:
// From the GCC man page:
//
// file.cc
// file.cp
// file.cxx
// file.cpp
// file.CPP
// file.c++
// file.C
// C++ source code that must be preprocessed. Note that in .cxx, the
// last two letters must both be literally x. Likewise, .C refers to
// a literal capital C.
//
// We emulate this with:
+cpp(.cc)
+cpp(.cp)
+cpp(.cxx)
+cpp(.cpp)
+cpp(.c++)
// Note the exceptions:
// +cpp(.CPP)
// +cpp(.C)
// These are commented out for the default config because they seem to
// cause trouble more often than not. For starters, it is problematic
// with filesystems that are case-insensitive (which has become common
// even on some POSIX systems).
// =============
// Size Options:
// +fwc // wchar_t might be builtin; if so, uncomment this option. (NOTE:
// // this option needs to be set before a size option is given for
// // wchar_t; see the documentation for -sw# in the Lint manual.)
size-options.lnt // This .lnt file should be generated (preferrably
// by a program created by invoking GCC with the compile options that
// are used in the compilation of the project to be linted). This
// happens automatically when 'make -f co-gcc.mak' is invoked.
// ===========================================
// +rw and -d options to cope with GNU syntax:
+ppw(ident) // Tolerate #ident
+ppw(warning)
// GCC provides alternative spellings of certain keywords:
+rw(__inline)
-rw_asgn(__inline__,__inline)
-rw_asgn(__header_always_inline,__inline)
-rw_asgn(__header_inline,__inline)
-rw_asgn(__signed__,signed)
-rw_asgn(__signed,signed)
-rw_asgn( __volatile__, volatile )
-rw_asgn( __volatile, volatile )
+rw(restrict)
-rw_asgn(__restrict,restrict)
-rw_asgn(__restrict__,restrict)
++d"__const=const" // gconv.h uses __const rather than const
++d"const=const" // ensure const expands to const.
-rw_asgn( asm, _up_to_brackets )
-rw_asgn( __asm, _up_to_brackets )
-rw_asgn( __asm__, _up_to_brackets )
// This re-definition of the various spellings of the asm keyword enables
// Lint to pass gracefully over expression-statements like:
// __asm __volatile ("fsqrt" : "=t" (__result) : "0" (__x));
// But it may be necessary to suppress certain error messages that are
// triggered by tokens that are part of an assembly declaration or
// statement. For example:
-d"__asm__(p...)=/*lint -e{19}*/ __asm__(p)"
// ...causes Lint to be quiet about the semicolon that follows an
// __asm__() declaration. Note, the -e{N} form of suppression takes

Using FlexeLint with GCC
These notes describe how to use the option file co-gcc.lnt which serves
as a replacement for the older co-gnu.lnt and co-gnu3.lnt options files.
--- Quick Start ---
If you just want a quick-and-dirty Lint configuration (one that enables
you to use Standard Library headers and system headers) then use the
makefile 'co-gcc.mak' (supplied with the Lint distribution) in an
invocation of GNU Make like so:
make -f co-gcc.mak
... which should generate the following files (provided that 'gcc', 'g++'
and 'awk' are each found in your $PATH):
lint_cmac.h
lint_cppmac.h
gcc-include-path.lnt
size-options.lnt
(co-gcc.lnt depends on these files, so they must be generated before you
do anything else.)
That's it! You should now be able to run:
flint co-gcc.lnt [source files]
Note that Lint must be able to find co-gcc.lnt and the files referenced
therein. If you want to keep them in a separate directory (e.g.,
/usr/local/etc/flint) from the one where you will invoke Lint (e.g.,
~/some-project/src), you'll need to specify the former with a '-i' option
so that Lint will know where to look. In that case, the invocation would
look like:
flint -i /usr/local/etc/flint co-gcc.lnt [source files]
If your project is compiled without any explicit command-line switches
other than '-c' then this invocation alone might be all that you need to
get started linting your project. Otherwise it probably won't suffice.
For a Lint configuration that better matches the way you compile your
code, you should at least read the 'usage' note at the top of co-gcc.mak.
For a motivation for the contents of co-gcc.mak, and to better understand
the configuration issues in general, please read on.
--- Introduction ---
The configuration of Lint for use with GCC-compiled sources is complicated
by two major issues:
First, GCC defines a large number of preprocessor macros internally (i.e.,
it defines a lot of macros for which there are no '#define' directives in
any source file that Lint can read.). Unless this issue is resolved for
each project, Lint will not see the same sequence of C/C++ tokens as GCC
when it tries to analyze your program, and as a result it will not see the
same set of declarations; consequently you'll see lots of spurious
messages because the analysis will reflect that of a program that is
truly ill-formed (unlike the program seen by GCC).
Second, GCC is aware of several built-in functions. Most of them can be
presented to Lint as ordinary forward-declarations of functions so as to
avoid undesired diagnostics claiming that these functions were not
declared before the first point of use. Note, these declarations do not
necessarily need to be presented to GCC.
--- Solving the Preprocessor Problem ---
Before we get started, we'll need an empty C source file. Call it
'empty.c' and save it to disk. Next, use your favorite command
interpreter environment (such as sh in Unix-like environments or cmd.exe
on Windows) and go to the directory containing 'empty.c'. Verify that you
can run GCC by doing the following:
gcc -v
If your environment is properly set up you should see a version string.
(You'll also want to verify that this is the same GCC executable used to
compile your sources; check the PATH environment variable or try running
'which gcc'.)
Assuming that worked, you can now try the following (and note that case,
as with C/C++ identifiers, is important.):
gcc -E -dM empty.c
On one system, we then see definitions like:
#define __DBL_MIN_EXP__ (-1021)
#define __FLT_MIN__ 1.17549435e-38F
#define __DEC64_DEN__ 0.000000000000001E-383DD
... followed by about a hundred more '#define' directives. What just
happened? We passed two options to gcc; the first one, '-E', means,
"don't run the compiler; just run the preprocessor". The option '-dM'
(not to be confused with '-DM', which is completely different) means,
"don't generate preprocessor output; instead, only dump all macro
definitions, including those defined internally".
With this output, we are now halfway to the point of having a preprocessor
configuration for Lint. First, let's redirect those macros to a file:
gcc -E -dM empty.c >lint_cmac.h
Next, let's test our configuration: make a simple C source file
containing the "Hello, world" program in a file called 't.c' (in the same
directory as 'empty.c')
#include <stdio.h>
int main () {
printf( "hello, world!\n" );
}
To lint this program, first copy the lnt file (co-gcc.lnt) and the
associated header (co-gcc.h) into the same directory. Next, create two
new empty files:
size-options.lnt
gcc-include-path.lnt
... and save them to disk. Then make a file called 'std.lnt' which will
(at first) contain only:
co-gcc.lnt
This tells Lint, "process the arguments in co-gcc.lnt". Two of those
arguments are:
-header(co-gcc.h) // #include's headers generated by GCC.
+libh(co-gcc.h) // Marks co-gcc.h as library code.
'-header(co-gcc.h)' means "behave as if each primary source file began
with '#include "co-gcc.h"'. (Note that co-gcc.h includes "lint_cmac.h"
when Lint runs in C language mode.)
Finally, try running:
/path/to/flint std.lnt t.c
... or, on Windows:
[drive-letter]:\path\to\lint-nt std.lnt t.c
Next we'll see output similar to the following:
FlexeLint for C/C++ (Unix/386) Vers. 9.00c, Copyright Gimpel Software
1985-2009
--- Module: t.c (C)
_
#include <stdio.h>
t.c 3 Error 322: Unable to open include file 'stdio.h'
What went wrong? The problem is that we haven't yet addressed the other
half of the preprocessor configuration, namely: the ordered sequence of
directories to search for system headers. Fortunately GCC already knows
this list and gives us a way to discover it. Just run:
gcc -c -v empty.c
On one system (specifically, Mac OS X on Intel), that yields a lot of
verbose output including these lines:
#include "..." search starts here:
#include <...> search starts here:
/usr/local/include
/usr/lib/gcc/i686-apple-darwin8/4.0.1/include
/usr/include
/System/Library/Frameworks
/Library/Frameworks
End of search list.
(Naturally, that list will look a bit different in different
environments.) To make Lint search for system headers in the same way, we
need to take that output from GCC and use it to make a set of options of
the form --i[directory]. E.g. on the same system, that means that in
gcc-include-path.lnt, I should place the following --i options:
--i/usr/local/include
--i/usr/lib/gcc/i686-apple-darwin8/4.0.1/include
--i/usr/include
--i/System/Library/Frameworks
--i/Library/Frameworks
(Note, arguments to Lint are processed in order, so the --i options must
appear before t.c or they will not take effect in time.)
In this case, none of the directory names contains a space, but if one of
them did we would have to surround its name with quotes as in:
--i"/usr/local/include"
Now let's try linting "hello, world" again:
/path/to/flint std.lnt t.c
This time we should see no error messages. Are we done yet? Not quite.
First, let's test our configuration against all of the C Standard Library
headers. Modify t.c to:
#include <assert.h>
#include <iso646.h>
#include <setjmp.h>
#include <stdio.h>
#include <time.h>
#include <ctype.h>
#include <limits.h>
#include <signal.h>
#include <stdlib.h>
#include <wchar.h>
#include <errno.h>
#include <locale.h>
#include <stdarg.h>
#include <string.h>
#include <wctype.h>
#include <float.h>
#include <math.h>
#include <stddef.h>
int main () {
printf( "hello, world!\n" );
}
... and try linting again:
/path/to/flint std.lnt t.c
This time you should see a number of messages; in particular, you should
see Info 766 issued for most of these headers since they were not used.
you may also see some legitimate warnings, and you may see an Error or two
about 'wchar_t'. (Note, if it seems as though your port of GCC recognizes
wchar_t as a keyword instead of an identifier then uncomment the use of
'+fwc' in your copy of co-gcc.lnt).
[NOTE: we should point out that the option -wlib(1) is in co-gcc.lnt for a
reason. Please note that we *strongly* recommend against the use of
options like -wlib(0) or -elib(*). If you see syntax error messages about
library header code, odds are that something is wrong with the Lint
configuration; so you'll do yourself no favors by silencing Lint when it
sees constructs that Lint's parser doesn't know how to handle. If you need
help with correcting your configuration, please check the Lint manual or
contact us.]
We should really be done now, right? Well, not quite. A remaining issue
is that the set of predefined macros (dumped into "lint_cmac.h" earlier)
depends not only on things like the target system and the version of GCC;
it also depends on the options that you pass to GCC when you compile your
program. E.g., if we invoke:
gcc -O3 -E -dM empty.c >lint_cmac.h
... then (with the version of GCC we tested) lint_cmac.h will no longer
contain a definition for the macro '__NO_INLINE__' and contains a new
definition for '__OPTIMIZE__'. So when you generate macros, you should be
careful to pass in the full set of options used when you compile.
Ideally, you should establish a target in your build system that
re-generates the predefined macro header whenever your build configuration
changes; that way you'll seldom need to think about it again and Lint's
preprocessor configuration will always match the compiler's.
Assuming you've generated the right set of predefined macros for your
build settings, you should now try Linting a single primary source file in
your project. Since we're just starting out, let's run with -w1 (i.e.,
with the warning level set to one) so that we can deal with any syntax
errors that pop up:
flint std.lnt -u -w1 some-project-file.c
Again, remember that syntax errors at this stage are likely due to a
misconfiguration; please check the Lint manual for likely remedies or
contact us if the solution is not obvious.
Once you've taken care of all syntax errors, try doing the same with all
project files. We recommend placing the name of each project file in a
.lnt file (often called project.lnt); e.g.:
file1.c
file2.c
[...etc.]
... and invoke Lint like so:
flint std.lnt -w1 project.lnt
When all syntax errors are resolved, you can begin turning on Warning
messages (i.e., those listed in section 17.4 of the Lint manual). You can
turn them on individually after '-w1' or you can instead use '-w2' and
then suppress the Warnings that are less severe. (For details on message
suppression, see section 5.2 of the Lint manual.)
At this point, you should be well-equipped to Lint any C program compiled
with GCC. However, C++ users have a couple more points to consider.
The command used to invoke GCC also affects the set of predefined macros.
Observe the difference in '#define' output when you invoke:
g++ -O3 -E -dM empty.c >lint_cppmac.h
diff lint_cmac.h lint_cppmac.h
Also, note that the list of directories to search for Standard Library
headers has some new additions when you use 'g++ -v -c empty.c' instead of
'gcc -v -c empty.c'. Your sequence of --i options should be set
accordingly.
That's about it for the preprocessor.
--- Size options ---
Finally, you'll need to establish sizes of primitive types. E.g. for a
64-bit platform this includes setting '-sp8' (indicating that pointers are
8 bytes wide). It often also involves setting '-sl8' (indicating that
'long' is eight bytes wide). As suggested earlier, the makefile
co-gcc.mak can generate these options for you.
If you find this tutorial to be lacking in some way, please contact us
(support@gimpel.com) with your suggestions for improvement.

# - target: the name of the target to which the sources belong. You will get a
# new build target named ${target}_LINT
# - source1 ... : a list of source files to be linted. Just pass the same list
# as you passed for add_executable or add_library. Everything except
# C and CPP files (*.c, *.cpp, *.cxx) will be filtered out.

# Example:
# If you have a CMakeLists.txt which generates an executable like this:

# set(MAIN_SOURCES main.c foo.c bar.c)
# add_executable(main ${MAIN_SOURCES})
#
# include this file

// macros-msc.cpp, which follows the form of -scavenge() output.
// We generated the options in this section with the following commands:
// %VSInstallDir%\vc\bin\vcvars32.bat
// cl /EP /C macros-msc.cpp
// The options for other build configurations will probably differ (which
// is why you should comment out the following if you use the macro
// generator).
// Also note: some of the following are defined for C++ mode but not for C
// mode; but there's no need to comment them out here because they are
// conditionally #undef'd in co-msc100.h.
-d_CPPRTTI{1}
//
// Defined for code compiled with /GR (Enable Run-Time Type
// Information).
//
-d_INTEGRAL_MAX_BITS{64}
//
// Reports the maximum size (in bits) for an integral type.
//
// NOTE:
// When generating 64-bit code, the definition for _M_IX86 must be
// commented out.
-d_M_IX86{600}
//
// Defined for x86 processors. See the "Values for _M_IX86 table" (in
// Microsoft's preprocessor documentation) for more information. This
// is not defined for x64 processors.
//
-d_M_IX86_FP{0}
//
// Expands to a value indicating which /arch compiler option was used:
//
// 0 if /arch was not used.
//
// 1 if /arch:SSE was used.
//
// 2 if /arch:SSE2 was used.
//
// See /arch (Minimum CPU Architecture) for more information.
//
-d_MSC_BUILD{1}
//
// Evaluates to the revision number component of the compiler's
// version number. The revision number is the fourth component of the
// period-delimited version number. For example, if the version number
// of the Visual C++ compiler is 15.00.20706.01, the _MSC_BUILD macro
// evaluates to 1.
//
-d_MSC_EXTENSIONS{1}
//
// This macro is defined when you compile with the /Ze compiler option
// (the default). Its value, when defined, is 1.
//
-d_MSC_FULL_VER{160030319}
//
// Evaluates to the major, minor, and build number components of the
// compiler's version number. The major number is the first component
// of the period-delimited version number, the minor number is the
// second component, and the build number is the third component. For
// example, if the version number of the Visual C++ compiler is
// 15.00.20706.01, the _MSC_FULL_VER macro evaluates to 150020706.
// Type cl /? at the command line to view the compiler's version
// number.
//
-d_MSC_VER{1600}
//
// Evaluates to the major and minor number components of the
// compiler's version number. The major number is the first component
// of the period-delimited version number and the minor number is the
// second component.
//
// For example, if the version number of the Visual C++ compiler is
// 15.00.20706.01, the _MSC_VER macro evaluates to 1500.
//
// In Visual Studio 2010, _MSC_VER is defined as 1600.
//
-d_MT{1}
//
// Defined when /MD or /MDd (Multithreaded DLL) or /MT or /MTd
// (Multithreaded) is specified.
//
-d_NATIVE_WCHAR_T_DEFINED{1}
//
// Defined when /Zc:wchar_t is used.
//
-d_WCHAR_T_DEFINED{1}
//
// Defined when /Zc:wchar_t is used or if wchar_t is defined in a
// system header file included in your project.
//
-d_WIN32{1}
//
// Defined for applications for Win32 and Win64. Always defined.

env-vc10.lnt: environment parameters for Microsoft's Visual C++ 10.0
If you are using Microsoft Visual Studio 2010 and you wish to invoke
PC-lint from that environment then add one or more commands to the
Tools menu as follows.
Simple Check
------------
For example, to add a simple facility to lint the current file you
may do the following:
1. From the Tools Menu choose "External Tools ..."
2. Click the "Add" button.
3. You will now be able to enter the fields of this Tool.
Modify them so that they approximate the following:
Title: PC-lint (Simple Check)
Command: c:\lint\lint-nt.exe
Arguments:
-i"c:\lint" std.lnt env-vc10.lnt "$(ItemFileName)$(ItemExt)"
Initial Directory: $(ItemDir)
X_Use Output Window __Prompt for arguments __Close on exit
Please note that you will have to change the "Command:" path if
the PC-lint Installation Directory is anything other than c:\lint
and you will have to change the "Arguments:" line if the
Configuration Directory is anything other than c:\lint
4. Select OK to return to the main environment.
This will result in the Tools menu containing the additional item
"PC-lint (Simple Check)". Checking 'X' on 'Use Output Window' is
important because in this way you can advance from error to error
using the F8 key (Shift F8 to reverse).
Strings of the form $(...) are called macros and can be typed in
directly as shown or can be selected from a menu by clicking
a right arrow in the dialog box. $(ItemFileName) refers to the
file name of the currently edited file without its path and without
its extension. $(ItemExt) is its extension. $(ItemDir) represents
the file's directory.
You will probably want to advance your new tool upward into the
initial position of all tools while you are testing and modifying the
command. You can do this by using the "Move Up" button that appears
on the External Tools dialog.
The benefits of using "Initial Directory" are that file-names in lint
error messages will not be so long, and, also, this directory can
contain a std.lnt that overrides the global std.lnt in the
Configuration Directory.
This Simple Check is fine to check stand-alone modules but to check
projects or to unit check modules that are in projects we need to
go a bit further ...
Project Creation
----------------
To lint an entire project we will need the names of all the modules
in the project. Visual Studio keeps these names (as well as some
appropriate options such as define options (-d...) and include options
(-i...) in a file named NAME.vcproj in the current project directory.
NAME is the name of the project and is identified by the macro
$(TargetName). PC-lint can read the .vcproj file and generate the
appropriate .lnt file. We recommend creating a tool for this purpose.
For this tool follow the steps 1-4 doing exactly the same thing as
above except in step 3, the information entered should be:
Title: PC-lint (Project Creation)
Command: c:\lint\lint-nt.exe
Arguments: -v -os("$(TargetName).lnt") "$(ProjectFileName)"
Init. Dir.: $(ProjectDir)
__Use Output Window __Prompt for arguments x_Close on exit
You will need to have an active project before this will work.
If you don't already have one you can obtain an active project
from the Solutions Explorer. You then click the newly added
"PC-lint (Project Creation)" tool on the tools menu to create
NAME.lnt.
The file created is an ASCII file and we recommend that you open it
within the IDE and examine it for any obvious flaws. This is your
chance to make any necessary modifications to the file as the process
of conversion may be less than perfect.
Project Check
-------------
Interestingly, by opening up the NAME.lnt file created above and
running the Simple Check described earlier you have the equivalent
of a full project check. However, we prefer to create a special
Project Check tool.
Now that we have a project file we can create a new tool called
"PC-lint (project check)". For this tool again follow steps 1-4 doing
exactly the same thing as above except in step 3, the information
entered should be:
Title: PC-lint (Project Check)
Command: c:\lint\lint-nt.exe
Arguments: -i"c:\lint" std.lnt env-vc10.lnt "$(TargetName).lnt"
Init. Dir.: $(ProjectDir)
X_Use Output Window __Prompt for arguments __Close on exit
Unit Check
----------
You can almost do a unit check on any single module by using the
Simple Check scheme suggested above. The only problems are that you
will need a -u option and you will not have the benefit of any -d or
-i options that have been placed into NAME.lnt created in the Project
Creation step. For this reason we suggest the following tool for
doing a unit check of any module that is part of a project and for
which a .lnt project file has been generated.
Title: PC-lint (Unit Check)
Command: c:\lint\lint-nt.exe
Arguments:
-i"c:\lint" std.lnt env-vc10.lnt --u "$(TargetName).lnt" "$(ItemPath)"
Init. Dir.: $(ProjectDir)
X_Use Output Window __Prompt for arguments __Close on exit
Note that $(ItemPath) will provide a complete path name and in the
absence of a project.lnt file it would cause full path names to
appear in messages. But a side effect of using the project file
with the --u option means that we adopt the shorter names used
in the project file.
Suppressing Messages
----------- --------
Suppressing messages is normally done by adding message suppression
options to a file. For example, -e550 will suppress message 550.
There are numerous other options to suppress messages.
As the documentation indicates, the file
c:\lint\options.lnt
(where c:\lint\ is the Configuration Directory) is the presumed
container of your overall suppression policy. (Note: options.lnt is
referenced by std.lnt). Add a message suppression here and you will
affect all linting employing that configuration.
To suppress messages for a particular project (or for all projects
within a given project directory) you may do the following:
Create a file std.lnt that is contained in the project directory.
Make it refer back to the std.lnt in the Configuration Directory.
Then add additional message suppression options or indeed any options
you want. For example it might contain:
c:\lint\std.lnt // reference to original std.lnt
-e550 // project-specific option
In this way suppression is limited to a particular project.
Tool Bar
--------
You also have the option of creating a PC-lint toolbar within your
Visual C++ IDE. First, create one or more tools as described above.
You will need to know the number(s) of the tool(s) you want to place
on the tool bar. This can only be done by the painful and laborious
task of counting. Using the list provided by "Tools"/"External
Tools", jot down the numbers (starting with 1 at the top) of all the
tools to be added to the tool bar. We recommend placing all the
PC-lint tools on a single tool bar. Then select Customize from the
Tools menu. Select the Toolbars tab and click the New... button.
Give the Toolbar a name (E.g., PC-lint) in the dialog box provided
and click "OK". Confirm that the new toolbar is now floating on
the desktop and that a check has been placed in the check box next
to the new toolbar name. Then click on the Commands tab and
select the "Toolbar:" radio button. Open the drop down list and
select "PC-Lint" from the choices. Click the "Add Command..."
button to reveal the "Add Command" window. In the "Categories:"
box scroll down to and select the "Tools" item. In the
"Commands:" box scroll down to and select the appropriate
"External Command" numbered item that corresponds to the desired
PC-Lint command, then click the OK button to add the selected item
to the PC-Lint toolbar. Repeat the "Add Command..." process for
each desired PC-Lint command the you wish to place on the PC-Lint
toolbar.
If you want to add a button image to the toolbar, you can choose one
via the Modify Selection button. Click Close and you now have your
own PC-lint for C/C++ button. (Note: If you change the location of
the PC-lint menu item on the Tools menu, you will change the subscript
and you will need to change the button(s) on the toolbar.)

\section into Introduction
The OpenBLT bootloader is an open source project, allowing everyone to access the
sources. One downside of this is that if someone knows the OpenBLT bootloader is used
in your product, it is relatively easy for them to figure out how to update the
firmware in your product. Although this could be a feature of your product, in most
cases it is not desirable.
For this reason the bootloader contains a seed/key security module. If this security
module is enabled in the bootloader's configuration, updates can only be made by users
that have the correct algorithm inside this Seed and Key shared library. If not, then
new firmware update requests are rejected by the bootloader.
The SeedNKey project is preconfigured to build this Seed and Key shared library. Its
default implemented seed and key algorithm works together with those implemented in
the OpenBLT demo bootloaders. You are free and encouraged to update this algorithm to
match your security needs.
On the bootloader target side (microcontroller), this security module is enabled by
setting configurable BOOT_XCP_SEED_KEY_ENABLE to a value of 1 in the bootloader's
configuration header file (blt_conf.h). The implementation of the seed and key algorithm
can be made in the hook-functions XcpGetSeedHook() and XcpVerifyKeyHook().
On the host side (PC), you simply specify the Seed and Key shared library file that this
preconfigured project built. In MicroBoot this shared library can be specified through
the settings user interface. In BootCommander it is specified via a command line option.
Refer to the OpenBLT website for additional information regarding the XCP Seed and Key
shared library, including step-by-step instructions on how to build it:
