RPI does not boot if HAT EEPROM is corrupted

[hifiberry]

I've seen a problem with a board where the EEPROM content wasn't written correctly. With older 3.x kernels the board boots, but not with the latest kernel/firmware. Is there any kernel parameter to ignore the ID PROM contents? This needs to be only temporary to write the correct EEPROM contents.

You can disable the EEPROM reading using the config.txt setting force_eeprom_read=0. I'll take a look at the reading code to see why it doesn't boot. If you can read the EEPROM contents and upload it somewhere (or email it to me) I can use it as a test case.

Thanks, will test this. I will see that I can find a card with this problem and send you en EEPROM dump.

Not corrupted, but here's a .EEP that fails to boot on Pi2. If I comment out the alternate functions GPIO lines it works.
