[possible BUG] Bug 458 might not be fixed completely Topic is solved

[dhampir]

I changed the code and started the system. Lets see what happens

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.

[Giovanni]

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?

Giovanni

[shinelikerain]

It always fails for writes

[Giovanni]

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

Here they are Giovanni.

Thank you for your help.
