I am working on a touch pad driver which uses i2c reads and writes to the touch pad registers. But, i observe the i2c reads are not consistent. when i try to read the Manufacturer information i get some junk values. when i try resetting all the register and read those values i get some other unexpected values.

I feel like its a serious OMAP3 I2C-2 timing issue.

         But with same uImage some times i get correct values.

Do any one know what i am missing on. and how to debug this issue.


Thankfull for your suggestions.
