Gumstix Verdex
Compiling
To set up build environment
source ~/gumstix/gumstix-oe/extras/profile
Executables for cross-compiling are stored in:
/home/brian/gumstix/gumstix-oe/tmp/cross/arm-angstrom-linux-gnueabi/bin
And the PATH can be set with:
PATH=$PATH:/home/brian/gumstix/gumstix-oe/tmp/cross/bin
To compile
arm-angstrom-linux-gnueabi-g++ cgi.cpp vfatregister.cpp vfatedit.cpp vfati2c.cpp -o vfat$i.cgi -lcgicc
And if you need to link against cgicc (for web interfaces) add both of the arguments
-I/home/brian/gumstix/gumstix-oe/tmp/work/armv5te-angstrom-linux-gnueabi/libcgicc-3.2.3-r0/cgicc-3.2.3 -L/home/brian/gumstix/gumstix-oe/tmp/work/armv5te-angstrom-linux-gnueabi/libcgicc-3.2.3-r0/cgicc-3.2.3/cgicc/.libs
Flashing the gumstix
http://osx-pl2303.sourceforge.net/
For the Mac install Minicom to communicate via USB-Serial adapter
sudo port install Minicom
as root use
minicom -s
to setup minicom parameters
speed baud parity and stop bit = 115200 8N1
If the Gumstix won't boot, you can (rather slowly) flash the filesystem over serial.
If the gumstix will boot, then flashing from RAM disk over ssh is faster, but if the process fails or gets interrupted you'll have to fall back on the serial method. Remounting the filesystem read-only may not work, and the whole processed failed. Reflash over ssh
Changes necessary from the default image
Boa config
Boa is a webserver designed for small/embedded platforms
In /etc/boa/boa.conf change the following lines:
| From | To |
|---|---|
| #ServerName www.your.org.here | ServerName gumstix |
| ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ | ScriptAlias /cgi-bin/ /var/www/cgi-bin/ |
Stop and then start boa with:
/etc/init.d/boa stop /etc/init.d/boa start
Add the following files
These are the files for the cgicc (C++ cgi script) library. Copy from the bitbake to the /usr/lib/ directory
- libcgicc.so.5
- libcgicc.so
- libcgicc.so.5.0.1
Install additional packages
ipkg install libstdc++6
Suid cgi-bin
Programs that run I2C directly need to be suid as root so they have permissions to make I2C system calls.
chown root ./vfat*.cgi chmod u+s ./vfat*.cgi
Add home PATH
- optional
Make a file in /etc/profile.d/ that contains the following:
#!/bin/sh export PATH=$PATH/home/root/bin:
