MCB2300 and SD-Card/MCI trouble

Hi,

I wanted to test the SD-card example from keil using the native MCI interface with an SD card.
It detects well an Formatted SDcard inserted but asks me forever to format the card and then , that the format failed...
When a took a look into the source, it seems
mci_init() return well (__TRUE value),
but when I did an mci_read_sect in order to read the sector 0, it failed.
I really didn't find what's wrong...

Best Regards

  • There's some progress :)

    The inserted card is always detected as unformated.
    I can format it from the board and it seems it's working well . But the mcb2368 board always says it's not formatted...
    Nevertheless, the DMA ram tip solved on part of the problem :)

    hyperterminal:

    SD/MMC Card is Unformatted
    Format Flash Memory Card? [Y/N]
    Memory Card Formatted.
    Card Label is M:KEIL
    SD Card Detected (CID:5252797)
