These are the modules I used, for 0.1.10 b160. Installed them with opkg --force-depends
kmod-i2c-gpio-custom_4.4.46-2_mipsel_24kc.ipk
kmod-i2c-gpio_4.4.46-1_mipsel_24kc.ipk
kmod-i2c-algo-bit_4.4.46-1_mipsel_24kc.ipk

And I added this init.d script:

#!/bin/sh /etc/rc.common # Creates bit-banged i2c-device /dev/i2c-1 on pins 5,4. # NOTE: This hides /dev/i2c-0! START=98 STOP=97 start() { omega2-ctrl gpiomux set i2c gpio insmod i2c-algo-bit insmod i2c-gpio insmod i2c-gpio-custom bus0=1,5,4 } stop() { rmmod i2c-gpio-custom rmmod i2c-gpio rmmod i2c-algo-bit omega2-ctrl gpiomux set i2c i2c }
