The problem of SD Card driver on Windows Embeddeompact 7. RRS feed

  • Question

  • On my project,porting the bsp from wince6.0 to wince7.0,and my cpu is pxa310.
     There are three SDIO interfaces on pxa310. First one is unused.Second one is assigned to the SD card.Third one is assigned to the WIFI.
     The wifi device is working properly both wince6.0 and wince7.0.
     On wince6.0 platform, the sd card is working properly ,the os could detect the event that the sd card is inserted,and display the flag in My Device.
     On wince7.0 platform,the os could detect the event that the sd card is inserted,but could not display the flag in My Device.
    Both wince6.0 platform and wince7.0 platform are running in the same development board.

    I can not find a solution to resolve the problem.
    Could you help me?

  • Hi

    You can check the registry details in common.reg / platform.reg to determine if something is different in the BSP settings that you are using.

    Also be sure you are setting the right sysgen /BSP variable i.e. you are selecting the right driver for SD (standard host controller provided by MS or custom SD host controller). Try setting SYSGEN_SD_MEMORY variable in your BSP and do a build. Other than this you would have to compare the code.
