How to use EEPROM

Overview

The IGEP expansion boards (except IGEP New York) provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).

Play with EEPROM memory

Use i2c-tools to manage it:

i2cget <bus> <chip> <register>
i2cset <bus> <chip> <register> <value>

IGEPv2 Expansion

For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:

i2cset -f -y 2 0x50 0x10 0x22
i2cget -f -y 2 0x50 0x10

IGEP PARIS Expansion

For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:

i2cset -f -y 3 0x51 0x10 0x22
i2cget -f -y 3 0x51 0x10

IGEP BERLIN Expansion

For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:

i2cset -f -y 3 0x51 0x10 0x22
i2cget -f -y 3 0x51 0x10
