I have been writing a program for the 324PB, and when I try to program the EEPROM I get this error: "Verifying EEPROM...Failed! address=0x0002 expected=0x25 actual=0x05"
Interestingly, the details of this message change from time to time, like yesterday it failed on address 0x0000.
I have some 324PBs on custom PCBs that I am programming using JTAG and the AVR Dragon. I also have a few 324PB Xplained Pro boards, using the EDBG interface. The Xplained boards also fail, but they work sometimes, unexpectedly. The Xplain failed today with "Verifying EEPROM...Failed! address=0x0001 expected=0x05 actual=0x00".
Does anyone know why this would be happening across interfaces and chips? I surely haven't blown out ALL of the EEPROMs I have.
