The newly manufactured EL502 Mezzanine cards do not contain any data in their EEPROM yet. A Raspberry Pi and a custom made cable are used to programm the EEPROM.

The code of this project is under version control in a Git repository whose upstream is: https://git.gsi.de/BEA_HDL/V_DIO_EEPROM_Programming

• connect the custom made cable to the Raspberry Pi and to the Mezzanine
• activate the I2C interface of the Raspberry Pi: sudo raspi-config, browse to Interfaces and activate I2C
• copy the src folder to the Raspberry Pi or clone the Git repository on it

• cd src
• ./write_i2c_data.py

This will program the content of src/eeprom_content.csv to the EEPROM.

• cd src
• ./read_i2c_data.py

This will create an output file src/eeprom_content_readback.csv.

You can compare it to the desired content using diff eeprom_content_readback.csv eeprom_content.csv.
