Hi

Has anyone got an SD Card or MMC talking to the Discovery board yet? I can't find much information on the forum. Can anyone, point me in the right direction?

Thanks in advance

Amir

Review the schematics from other STM32 development boards that support the features you want. ie from ST, Keil, IAR/Olimex, etc

thanks for the quick reply, Clive1.

I meant from a software point of view? I understand the STM32VL Discovery does not support SDIO. That's why I assume I might need to use SPI. But exactly how, I'm not sure.

Any ideas?

Thanks again

Amir

''I might need to use SPI. But exactly how, I'm not sure''

The SD Card neither knows nor cares what controller you use, nor what board it is mounted on; you just need to follow the standard procedures which are well-documented on many web pages:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
