Hello,

I am trying to access my i2c eeprom (custom board) from MotaVista's
HardHat Linux (kernel 2.4.0-test2).

Here is a snippet from my kernel config:
#
# I2C support
#
CONFIG_I2C=y
# CONFIG_I2C_ALGOBIT is not set
# CONFIG_I2C_ALGOPCF is not set
CONFIG_I2C_CHARDEV=y

How can I enable i2c support for the 405 ? /proc/bus/i2c is empty. I
expect the 405 i2c adapter listed there ! Am I right ?

Matthias

You need to select:

CONFIG_PPC405_I2C_ALGO=y
CONFIG_PPC405_I2C_ADAP=y

These drivers are part of the latest M.V kernel.

linux/drivers/i2c/i2c-adap-ppc405.c
linux/drivers/i2c/i2c-algo-ppc405.c
