[Gumstix-users] I2C Problems

[Andy K. <akl...@gm...>]

Hi,

I have a connex-400bt (release 1161), cf-stix and robostix. I am
trying to enable I2C between the connex and robostix.

I have followed the steps on the wiki, successfully reflashing the
system with a new build and am trying to test it out.

When using modprobe i2c-dev and modprobe i2c-pxa I receive the following errors:

modprobe i2c-dev
WARNING: Error inserting i2c_core (/lib/modules/2.6.20-rt5gum/kernel/sound/i2c/i
2c-core.ko): Invalid module format
FATAL: Error inserting i2c_dev (/lib/modules/2.6.20-rt5gum/kernel/drivers/i2c/i2
c-dev.ko): Unknown symbol in module, or unknown parameter (see dmesg)
# modprobe i2c-pxa
WARNING: Error inserting i2c_core (/lib/modules/2.6.20-rt5gum/kernel/sound/i2c/i

FATAL: Error inserting i2c_pxa (/lib/modules/2.6.20-rt5gum/kernel/drivers/i2c/bu
sses/i2c-pxa.ko): Unknown symbol in module, or unknown parameter (see dmesg)

At the end of dmesg:

i2c_core: version magic '2.6.18gum mod_unload ARMv5 gcc-3.4' should be '2.6.20-r
t5gum preempt mod_unload ARMv5 '
i2c_dev: Unknown symbol i2c_get_adapter
i2c_dev: Unknown symbol i2c_master_recv
i2c_dev: Unknown symbol i2c_register_driver
i2c_dev: Unknown symbol i2c_transferter

i2c_pxa: Unknown symbol i2c_del_adapter
i2c_pxa: Unknown symbol i2c_add_adapter

I'll note that my system was originally a version 1161 and when I
reflashed it, it is now 1374M.

I'm guessing I need to update these I2C files, but how do I go about this?

Thanks for the help,
