STM32F429 and sdcard

[vahid4134]

I used testhal to test sdcard(SDIO). But fail on connecting.

I try to change Pal Model to

Code: Select all

   palSetPadMode(GPIOC, 8, PAL_MODE_ALTERNATE(12)); 
   palSetPadMode(GPIOC, 9, PAL_MODE_ALTERNATE(12)); 
   palSetPadMode(GPIOC, 10, PAL_MODE_ALTERNATE(12)); 
   palSetPadMode(GPIOC, 11, PAL_MODE_ALTERNATE(12)); 
   palSetPadMode(GPIOC, 12, PAL_MODE_ALTERNATE(12)); 
   palSetPadMode(GPIOD, 2, PAL_MODE_ALTERNATE(12)); 

and then waiting on connection.
I'm tested my device with stm32fcube and work good.

That demo is done to run on a F407. There are differences in the board files and configuration files.

You don't provide sufficient info for a suggestion.

I just use main.c functions. I use stm32f429 configuration file.
I checked with gdb and my program waiting on

Code: Select all

//ChibiOS/os/hal/ports/STM32/LLD/SDIOv1/sdc_lld.c:574
while (((sta = sdcp->sdio->STA) & (SDIO_STA_CMDREND | SDIO_STA_CTIMEOUT |
                                     SDIO_STA_CCRCFAIL)) == 0)

There are two possible causes:

1) Clocks to SDIO.
2) Pins setup (or wrong board file).

Please verify settings in one of those board files that have SDIO.

Thank you for response and sorry Im begginer in Chibios.
My hardware with stm32fcube work good.
I attach my code. Please check my code
I dont know why waiting in connection.

this is my bt of gdb

Code: Select all

I changed PIN setup in board.h and finally work.
Thank you
