Hi,

I am using LogicPD's Zoom AM1808 eXperimenter Kit with ti-sdk-am180x-evm-4.0.1.0 having linux-2.6.33-rc4-psp03.20.00.14.sdk & tisdk-rootfs-am180x-evm arago file system. The i2c-0 node is not visible under /dev directory. I want to access i2c-0 from user space. How can I get the i2c-0 node under /dev ?I want to use user LED1, LED2 & S2 DIP switches.

 

Regards,

Jitendra

    The kernel must be compiled with i2c dev support.. Odds are it already is. Usually there is an i2c line in the bootup logs. Look under drivers menu in the kernel config.

    TI has an unusual naming of i2c device files. Controller I2C0 will show up as /dev/i2c-1. They seem to reserve /dev/i2c-0 for something else?
