I am facing some i2c issues on omap3430 with linux 2.6.24 kernel.
My device is a slave sitting on I2C2 of OMAP3430.
I am observing the following,
1) Sometimes i get "i2c_omap.2: controller timed out"
i2c_omap.2: No acknowledmentif i use i2c 2 at 100khz
and i dont find them when i run at 400khz.
2) Sometimes the i2c write and read succeeds but data received is junk.
3) The I2C reads are not consistent. with same image if i boot
The readed values keep variying.
I am not sure what could be the problem. The mux settings seems okay.
The client creation seems fine. Can any one suggest me the exact
i2c bus registration steps. right now i only have
omap_register_i2c_bus(1, CONFIG_I2C_OMAP34XX_HS_BUS1, NULL, 0);
in the board file. and
MUX configurations in the
Am i missing something?
