Did you get anywhere with this?
I cant write to a card as the driver fails in
sdc_lld_wait_transaction_end() because of:-
Code: Select all
if ((SDIO->STA & SDIO_STA_DATAEND) == 0) {
osalSysUnlock();
return HAL_FAILED;
I'm using a STM32F407 DISCO with the STM32F4DISCOVERY Base Board. The tried the
testhal() too and that also fails.

Could you try the workaround I proposed few posts before?

Hi Giovanni,
I changed to:-
Code: Select all
while ((SDIO->STA & SDIO_STA_DATAEND) == 0)
;
And it hangs there. Reads are fine, writes always fail.

Thanks for info, I will give it a try again.
Could you provide some info about your setup? I need to replicate the problem.

I took your ChibiOS 3 demo RT-STM32F407-DISCOVERY and modified board.h to allow SD3, Ethernet and SD Card on the STM32F4DISCOVERY Base Board.
I have lwIP and FatFs in the build and the makefile has -O0 for debug.
SD Card is a SanDisk Ultra. Reads have always worked 100% but when I came to use writes to support lwIP CGI I've hit this problem.
Many thanks Giovanni

Does it happen for each single write or it is a random event?

Please post your board files, I suspect the problem could be there.
