stm32f4 SDIO setup

[daviddawe1982]

This is my board.h I think it is correct..
I think that I do get a responce as it hits this..
*resp = SDIO->RESP1;
HAL_SUCCESS;
Then cannot detect card..

How can I tell if it is correct? it is correct if it matches your board.

Just a note about board files, those are not written/modified, board files are generated by an utility included in ChibiStudio starting from XML files with .chcfg. Using the generator ensures that the file are at least formally correct.

Search .chcfg in the forum and details will pop up.

So after a bit more work I have got the sd to connect and mount but now i get this error.
FR_DISK_ERR.
What could be causing this?
My Test Code.

Hi,

Could still be I/O setup problems, check the data lines of SDIO. Long wiring could be another reason.

[daviddawe1982]

Well I think you are right it must be my interface as I switched to the spi interface I had on the back of my LCD and it worked perfectly I have ordered a prebuilt sdio interface I will wait for it to arrive and try again.
Thank you for all your help.

[Giovanni]

This happened already, long wires or lack of terminations, it can be critical.
