I've got a BeagleBone White that has suddenly stopped booting up after we tried to make a board change to disable the RTC clock.
The symptom is the power LED comes on and I get one line of text out the serial port, the line identifying version and build date of SPL U-Boot.
I've debugged the code to the point of determining that it hangs up in the gpmc_init() function in arch/arm/cpu/armv7/omap-common/mem-common.c, specifically it hangs on any of the writes to the GPMC registers in that function. I'm fairly puzzled as those writes look pretty innocuous.
Can anybody give me a clue as too what might have gone wrong. Or recommend any additional steps to take for debugging?
Thanks,
Matt S.
