    Hi Vinoth,

     

    As far as I know, there is pin mux conflict between nand and sd. So, even you select both, only one would work unless you can change pin mux.

    Hello yan,

     

    Right now I am using the "Omap L138-EVM Kit provided by Logicpd". I am trying to clone the BSP provided by them and rebuild an Win CE using visual studio.

    I have problem selecting both SD host controller and Nand Flash. I am not able to enable both at a time. So,my WINCE doesn't detect SD card even though there is an SD card slot in the EVM kit.

    Can you tell me if there is a way to edit the BSP , so that it lets me enable both the SD and Nand flash  together.
