I can’t get the code for the SD slot working. I see on a scope that the spi signal is going to the card but the card never responds. In the MMC code I noticed it does not say anything about SD. Has anyone ever made this dev board’s SD slot work? Any help would be appreciated.
I still have not had any success, but here is a link if anyone is interested in SD cards.
I found out why I can’t find SD specs anywhere.
"We are no longer allowed to give out any SD product
manuals/specifications. The customers can download the simplified
version of the manual from the SDA website below. If you wish to get the
full spec, you will have to join the SDA association.

Does anyone have an SD manual I could maybe get? That link to join up and get the manual sure is dead.
Hi, I see to be having the same problem with my Olimex SAM7S64 board that you mentioned… I can see all of the SPI signals going over the wires to the MMC controller on my scope, but there’s no response on the MISO line running back into the chip.
I believe I’ve got everything configured properly, and I know SPI is working (I’ve got an SPI LCD display on another chip select.)
Has anybody successfully used the card reader on this board?
we have source code on our web for the MMC card read/write which is tested to work, why don’t you check it ?

where is the code?
