Re: [Gumstix-users] verdex i2c missing

[Grahame J. <gb...@th...>]

Hi,

Looks to me that you do not have the i2c modules built.

cd build_arm_nofpu/linux-2.6.21gum
make ARCH=arm menuconfig
Go to drivers->i2c
enable i2c modules
Save

make ARCH=arm clean

cd ../../
make

vi build_arm_nofpu/root/etc/modules
Add:
i2c-dev
i2c-pxa

make
load new rootfs

Cheers

Grahame
