SD CARD on C5509

Henrique Thiesen

Hi all

I have a board evm5509 (Spectrum Digital) and I am using a SD CARD. With base in the application SPRA808A succeed

to write and to read in the first block according to the example, but when trying to write sequentially DSP it locks in the function MMC_write (mmc0, Addr, data, 512).

What can be happening wrong? When it locks the variable Addr is 118.

while( Page < nBlocks ) {

Addr = (Uint32)(Page) * 512;

MMC_write( mmc0, Addr, data, 512 );

Page++;

}

Best Regards

Henrique,

Which version of SD EVM are you using? Mine does not have an SD/MMC socket. How are you interfacing to the board? Does it have C5509 or C5509A?

Thanks.

Tommy,

My kit is DSK5509A. This board does not have SD/MMC socket, I connect by wires the SD/MMC socket in the connector P2A of board DSK. The pinout i get of schematic EVM5509A plus. The processor is C5509A.

Henrique,

I don't have a good answer for you yet, but I have found that the SD/MMC interface does not support SDHC cards. So I wanted to check with you and find out what type of card you are trying to access?

Thanks.
