[edit] Board Validation Test

If you downloaded the test-validation binaries the following actions will occur on bootup. Source is located at /bin/panda-test.sh

[edit] Setup

PandaBoard

• H2H-(HDMI-Type-A to HDMI-Type-A)
• USB thumb drive connected to USB port

[edit] Framebuffer random data

Command

dd if=/dev/urandom of=/dev/fb0 bs=1024 count=8100

[edit] LED Status Test

Command

echo none > /sys/devices/platform/leds-gpio/leds/pandaboard\:\:status1/trigger
echo 0 > /sys/devices/platform/leds-gpio/leds/pandaboard\:\:status1/brightness
sleep 1
echo none > /sys/devices/platform/leds-gpio/leds/pandaboard\:\:status2/trigger

[edit] Thumb Drive R/W Test

This test is used to check the USB connection by transferring a file to a thumb drive and verifying the md5sum value. This test will run at startup and will output the result. Make use you have a USB thumb drive connected at startup.

Source

echo -n "Thumb drive transfer test: "                                           
mount /dev/sda1 /mnt/thumb  > /dev/null 2>&1                                    
temp=$?

cd /home/root  > /dev/null 2>&1                                                 
cp testdata.* /mnt/thumb  > /dev/null 2>&1                                      
sync           > /dev/null 2>&1

md5sum -c testdata.md5  > /dev/null 2>&1                                        
temp=$?
