hi
I'm trying to use i2c bus over gpio pin on a microtik routerboard 133c with adm5120 processor
I followed instructions found here:
http://linux-adm5120.sourceforge.net/openwrt/i2c/
and things seems easy ... but it don't work !
especially in kernel configuration section of the above pageI'm unable to find the i2c-gpio-custom driver in kernel_menuconfig menus
moreover the kernel command line in the compiled kernel never include the option i added... the compile process seems to discard it !
if i add it manually (editing the compiled kernel with an hex editor) i get a message "unknown boot option i2c-gpio-custom..." at boot time
what is wrong ?
please help me ... i'm trying it since 5 days ! (in spare time naturally...)
thanks
