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

Serial Com using Macbook USB

I was able to use the USB port of my Macbook pro to communicate with the Gumstix using a USB to serial cable and a serial adapter plugged into the gumstix board.

Minicom and the Virtual comport driver were two pieces of software I needed to install on the Macbook.

I now try the virtual com port

Installing Minicom was easy if you have already install MacPorts. The command is

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.

Correct alignment of the TTL RS232 adapter

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:
