    Baytrail PCH-SMBus Modify Clock Frequency

    hazzel Green Belt

      Hi,

       

      We created a BSP for custom Baytrail platform based on yocto dizzy release of valleyisland device. The Linux SMBus driver for Baytrail platform operates by default at 100 kHz. We are required to connect an device of 60 KHz.

       

      As per atom e3800 datasheet, SMBus can be operated at speeds ranging from 10 kHz to 100 kHz. But I am not sure how to configure the SMBUS to operate on 60 kHz.

       

      Can you please guide me
