A few modules being used on custom boards are now failing to boot. Not even the welcome message from MB2 is seen on the console. The only messages seen are:
[0000.040] C> Failed to update boot chain
[0000.043] C> ERROR: Highest Layer Module = 0x54, Lowest Layer Module = 0x54,
Aux Info = 0x1, Reason = 0x2
We are using R28.2.1.
We suspect that this may be caused by power cycling early in the boot sequence.
