I need some help to debug an issue which I presume happens when the ROM bootloader tries to load the flash bootloader:
Code: Select all

This device got returned by customers after it was used in service for two months without a hitch. It's not a strapping pin issue.
My suspicion is that some of the flash memory got corrupted, but I cannot acknowledge which part. How to interpret the "load" statements?
Which checksum fails?
