Appendix: System Setup
|
|
======================
|
|
|
|
Serial Console Access
|
|
---------------------
|
|
|
|
As most current development machines don't have serial ports, the usual setup
|
|
is to use a USB-Serial-Converter. Some evaluation boards have such a converter
|
|
on board. After connecting, these usually show up on your host as
|
|
``/dev/ttyUSB#`` or ``/dev/ttyACM#`` (check ``dmesg`` to find out).
|
|
|
|
On Debian systems, the device node will be accessible to the ``dialout`` group,
|
|
so adding your user to that group (``adduser <user> dialout``) removes the need
|
|
for root privileges.
|
|
|
|
Using the "screen" program
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The terminal manager ``screen`` can also be used as a simple terminal emulator::
|
|
|
|
screen /dev/ttyUSB0 115200
|
|
|
|
To exit from ``screen``, press ``<CTRL-A> <K> <y>``.
|
|
|
|
Using the "microcom" program
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
A good alternative terminal program is microcom. On Debian it can be installed
|
|
with ``apt-get install microcom``, on other distributions it can be installed
|
|
from source:
|
|
|
|
http://git.pengutronix.de/?p=tools/microcom.git;a=summary
|
|
|
|
Usage is simple::
|
|
|
|
microcom -p /dev/ttyUSB0
|
|
|
|
Network Access
|
|
--------------
|
|
|
|
Having network connectivity between your host and your target will save you a
|
|
lot of time otherwise spent on writing SD cards or using JTAG. The main
|
|
protocols used with barebox are DHCP, TFTP and NFS.
|
|
|
|
Configuration of dnsmasq for DHCP and TFTP
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The ``dnsmasq`` program can be configured as a DHCP and TFTP server in addition
|
|
to its original DNS functionality::
|
|
|
|
sudo ip addr add 192.168.23.1/24 dev <interface>
|
|
sudo ip link set <interface> up
|
|
sudo /usr/sbin/dnsmasq --interface=<interface> --no-daemon --log-queries \
|
|
--enable-tftp --tftp-root=<absolute-path-to-your-images>/ \
|
|
--dhcp-range=192.168.23.240,192.168.23.250
|
|
|
|
Configuration of a TFTP Server
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Configuration of a BOOTP / DHCP Server
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Configuring a NFS Server
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
