I have a mega2560 R3 arduino board. I created a simple sketch from the Arduino IDE from file->Examples->EEPROM->eeprom_clear and then modified it to write 0x00112233445566778899aabbccddeeff repeating to the eeprom memory. After writing out these values and then using avrdude to read them back I get 0x00112233445566770011223344556677 instead. I have a custom programmer that read back the expected values correctly.

The avrdude command I am using for reading out the eeprom is:
avrdude -p atmega2560 -c wiring -P COM4 -b115200 -U eeprom:r:dump.bin
