Part Number: TM4C123GH6ZXR

I am seeing occasional random failure of EEPROM corruprion only at the firat address of each 32 word block of EEPROM.  Product reads/writes EEPROM at power up. Product in production. !! Urgent !! Please contact immediately.

    Hi Mike,

    For the EEPROM corruption when does this happen during the power up sequence? If this happens before the device is fully powered it can cause some issues. I would recommend using the brown out monitor to make sure there's no issues with the power supply.

    The other possible issue would be the working bit being cleared in teh EEDONE register before writing to EEPROM. Please ensure the "WORKING" bit is cleared. For more information see section 8.5 of the datasheet.
