V-DIO EL502 EEPROM Programming
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.
Resources
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
How to program the EEPROM
- connect the custom made cable to the Raspberry Pi and to the Mezzanine (TODO: add image)
- activate the I2C interface of the Raspberry Pi:
sudo raspi-config, browse toInterfacesand activate I2C - copy the
srcfolder to the Raspberry Pi or clone this repository on it
| Raspberry Pi | Raspberry Pi | Mezzanine | Mezzanine |
|---|---|---|---|
| pin number | signal name | pin number | signal name |
| 1 | +3.3 V | 1 | +5 V |
| 3 | SDA | 3 | SDA |
| 5 | SCL | 2 | SCL |
| 6 | GND | 26 | GND |
Programming
cd src./write_i2c_data.py
This will programm the content of src/eeprom_content.csv to the EEPROM.
Verification
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
