eeprog is a Linux C program designed for reading and writing to 24Cxx EEPROMs. Similar to PiPROM, eeprog depends on the i2C-Tools package to access EEPROM chip data. One notable advantage of eeprog is its hardware non-bias: eeprog has been successfully used for dumping eeprom.bin files from a Raspberry Pi 4. In theory, eeprog should work for any hardware with GPIO and linux support.

Once you have eeprog installed, dumping the firmware is done by simply running:

sudo ./eeprog /dev/i2c-1 0x54 -r 0:256 > eeprom.bin
