Sandbox
|
|
=======
|
|
|
|
barebox can be run as a simulator on your host to check and debug new non
|
|
hardware related features.
|
|
|
|
Build barebox for simulation
|
|
----------------------------
|
|
|
|
the barebox sand box can be built with the host compiler::
|
|
|
|
ARCH=sandbox make sandbox_defconfig
|
|
ARCH=sandbox make
|
|
|
|
Run sandbox
|
|
-----------
|
|
|
|
::
|
|
|
|
$ barebox [\<OPTIONS\>]
|
|
|
|
Options can be::
|
|
|
|
-m, --malloc=\<size\>
|
|
|
|
Start sandbox with a specified malloc-space \<size\> in bytes.
|
|
|
|
::
|
|
|
|
-i \<file\>
|
|
|
|
Map a \<file\> to barebox. This option can be given multiple times. The \<file\>s
|
|
will show up as /dev/fd0 ... /dev/fdx in the barebox simulator.
|
|
|
|
::
|
|
|
|
-e \<file\>
|
|
|
|
Map \<file\> to barebox. With this option \<file\>s are mapped as /dev/env0 ...
|
|
/dev/envx and thus are used as default environment. A clean file generated
|
|
with dd will do to get started with an empty environment
|
|
|
|
::
|
|
|
|
-O \<file\>
|
|
|
|
Register \<file\> as a console capable of doing stdout. \<file\> can be a
|
|
regular file or a fifo.
|
|
|
|
::
|
|
|
|
-I \<file\>
|
|
|
|
Register \<file\> as a console capable of doing stdin. \<file\> can be a regular
|
|
file or a fifo.
|
|
|
|
::
|
|
|
|
-x, --xres \<res\>
|
|
|
|
Specify SDL width
|
|
|
|
::
|
|
|
|
-y, --yres \<res\>
|
|
|
|
Specify SDL height
