I am hoping if someone can give  me some advice.

I have an eink AM300 prototype kit and we have had a problem
where we accidentally ran an "rm -r" from the root folder of gumstix.
Obviously this was not a great thing to do.

We then tried to rebuilding the flash
the system blocked at the reset command. Upon reboot, gumstix was not
working and we could not access it anymore. Below are the some of the
commands from the guide that we followed.

*GUM> mmcinit
GUM> fatload mmc 1 a2000000 u-boot_1427.bin
GUM> protect off all
GUM> era 1:0-1
GUM> cp.b a2000000 0 ${filesize}
GUM> reset

any help would be greatly appreciated.
