I am using a DM8148 custom board with  linux 2.6.37 which i got in PSP-04.01.00.07.  When I am enabling the eMMC in the kernel, I am stuck up with the following errors, Can you please suggest me how to resolve those things?

    You are using very old version of the PSP. Can you try with the newest PSP-04.04.00.02:

    Could you please provide full log (u-boot + kernel boot up).

    Are you planning to boot from eMMC? DM814x has 3 instances of MMC/SD/SDIO controller (suffix 0,1 or 2). Booting is supported from MMC/SD/SDIO1 only. DM814x ROM Code is incompatible with most eMMC devices which are >2GB.

    Best regards,

    I have followed the related document for detecting eMMC in the kernel.

    2474.MMC.rtf

    your help will be highly appreciated.

    Debasish,

    I am working on DM8148 EVM, where I have no eMMC, thus what I can do is to provide you some hints.

    It was not clear from your last post, if you try with the latest PSP 04.04.00.02? Or with the PSP from the latest EZSDK 5.05.02.00, which is PSP 04.04.00.01?

    Regards,
    Pavel
