SD/MMC starterware test

Other Parts Discussed in Thread: OMAP-L138

Hi.

In the starterware software, is there any source code for testing SD/MMC interface?? couldn't find any...

Also, we have a board that does not load, when testing under JTAG:

Scripts->OMAL L138 Memory Map->Setup Memory Map
Scripts->Frequency Settings->Core_300Mhz_mDDR_150Mhz
Load Program X....

All boards pass this test except one board, which fails at "Core_300Mhz_mDDR_150Mhz" setup.
What could be the cause for such failure on that board??? 

King Regards

    I ported the Startware SD Card example from the AM335x to C6748. I post it here:

    Can you please attach the screen shot of the problem ?
    Which line is causing the problem in function "Core_300Mhz_mDDR_150Mhz" ?

    In addition to Norman, TI has some of MMC/SD examples.

    You can get the MMC/SD example from BIOS PSP Package. (BIOS based example)

    Refer to the user guide.

    Can you please try to enable the adaptive clock in your emulator target configuration settings ?
