Hi all, I have a ROACH board, rev 2, which fails to boot up. It starts, then turns off all the LEDs, then tries again, before giving up after several attempts.
Using XPORT it reports that: Flash crashlog: Crash at 123695058649373s system time caused by channel 28 (2V5 PS (volts)) with value 2.36 This says that the 2V5 regulator, U53, is not producing the correct voltage. I should note that this board used to work fine, but recently stopped. Has anyone else had this problem before? I suppose that the appropriate solution is to replace U53 -- any guidance on whether this is the appropriate solution?
