MMC Over SPI Troubles With Embest Board

[abbyj]

Hi Gents,

I've tried compiling the demo for the STM32F4 and have updated my board files (Thank you Tectu for your help with the board files!), but I am still not able to access the SD card. I have tried a SanDisk 4GB and a Crucial 1GB.

Where else should I be looking to find my problem? Is there a setting that needs to be TRUE/FALSE in order for it to work? It appears that the InsertHandler/RemoveHandler is not running. Is there a particular frequency that needs to be set for it to work?


Thank you very much in advance for your help!

Hi,

In order to make those handlers work, you must provide the card detect code for your board in board.c.

On Embest board there is a GPIOB_PIN15 that is connected to ~CD of the card, so it should work as a card detect, only negated. It is not configured in Tectu's board files, however. Should be sth like this: GPIOB_SD_DETECT.

Can you please upload a .zip of your code containing your board files? There are different versions of Tectu's board files out there. I will try to get a final one together this weekend.
