If you fully configure your device using the SDcard. Then use a program
to copy the SD card to a USB stick. As long as you don't need to make
configuration changes, it should work just fine. If the device doesn't
boot reliably, the USB stick may not be getting recognized soon enough.
edit cmdline.txt and increase the waitusb value.
However........these edits might handle some configuration
cases........don't yell at me if this breaks everything :) the sdcard
device mmcblk0p? is referenced around 200 times in our code.
edit /opt/bootlocal.sh to look like this
Code:
--------------------
#!/bin/sh
# put other system startup commands here
GREEN="$(echo -e '\033[1;32m')"
echo
echo "${GREEN}Running bootlocal.sh..."
ln -s /dev/sda1 /dev/mmcblk0p1
ln -s /dev/sda2 /dev/mmcblk0p2
ln -s /mnt/sda1 /mnt/mmcblk0p1
ln -s /mnt/sda2 /mnt/mmcblk0p2
#pCPstart------
/home/tc/www/cgi-bin/do_rebootstuff.sh 2>&1 | tee -a /var/log/pcp_boot.log
#pCPstop------
--------------------
The 4 ln commands are what you want to add. I've only done some quick
testing, I'm sure certain parts of pCP will have problems. Please note
that this will most likely fail if you have more than one USB stick
inserted (as /dev/sda may change to a different USB device) insitu
upgrades will like likely fail as well. You will have to resize your
/dev/sda2 partition by hand too......
