How to flash/update the ID EEPROM?

The EEPROM on the HAT can be updated as follows. Before the update the WP jumper next to the EEPROM has to be closed.

  • Install EEPROM utils:

    $ git clone --depth=1 https://github.com/raspberrypi/hats
    $ cd hats/eepromutils
    $ make
    $ chmod +x eepflash.sh
    
  • Generate EEPROM data:

    $ wget https://github.com/watterott/RPi-Proto-HAT/raw/master/software/rpi-proto-hat.txt
    $ ./eepmake rpi-proto-hat.txt rpi-proto-hat.eep
    
  • Update/Flash EEPROM:

    $ sudo ./eepflash.sh -w -t=24c32 -f=rpi-proto-hat.eep
    

    Note: For a Device Tree Kernel add to /boot/config.txt the following line before flashing: dtparam=i2c0=on (before any dtoverlay statement).
