Did you un-write-protect the board eeprom?
Regards,
Pulled pin 7 (WP) to ground, yes. I've made the changes to U-Boot to
skip the check of the ID EEPROM and I'm now, through U-Boot, trying to
program the baseboard ID EEPROM with a proper signature. Linux version
3.8.13-bone35.1 starts to boot, but issues a Kernel Panic as seen here

[ 35.314342] Kernel panic - not syncing: Attempted to kill init!

[ 35.314342]
This is our custom board and I'm trying to eliminate any unknowns by
getting a good ID EEPROM signature setup up.
So, is U-Boot good to go, or should I get an older version from a BBW to
get the EEPROM programmed?
Thanks,
Ross
