The IGEP expansion boards (except IGEP New York) provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).<br>
= Play with EEPROM memory =
Use i2c-tools to manage it:
<pre>i2cget <bus> <chip> <register>
i2cset <bus> <chip> <register> <value></pre>
For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:
<pre>i2cset -f -y 2 0x50 0x10 0x22
i2cget -f -y 2 0x50 0x10</pre>
