How to get working with freeRTOS + SDIO + FATFS

[CJagt]

I have generated code using STM32Cubemx v.5.1 i have selected SDIO and FATFS and i want to use freeRTOS . so as soon as i enable freeRTOS my FATFS stops mounting performing operations. how to get working with both ?? any suggestion ??

We also faced such type of error but we moved with Stnd Pheripharle library.

According to me we face face such type of error when context switching not happen or context switching not properly worked at that time. So I suggest that debug your program .

I am sure this work but in embedded field very thing is possible.

@Khouloud ZEMMELI​  Hi , could you please provide me any updates??

​@CJagt​ 

Hello , in your ioc file you're only activated the FatFs and SDIO .

You found the error in the  generated code ?

Could you please give me more details ??    

Best Regards,

Hi @CJagt​ ,

Please set your heap and stack size to 0x1000, the curret used values 0x200 and 0x400 are too low for FreeRTOS and FatFs together

Sounds like something that could be automated.... and a recurring point of breakage/failure.

The default Keil ones break so much code that might actually do something, ie USB, media sectors, etc.

I am also facing same problem, once I enable freeRTOS my fatfs not mounting even after heap and stack size set to 0x2000. Any solution or any update on this?

[CJagt]

Hi @sm.18​  still I didn't found solution for this problem. I also tried with increased stack and heap size .

Finally I found the issue and made it working.

1. FATFS (Advanced Settings)---- I have enabled the DMA templete for FATFS.
2. SDIO(DMA Settings) ----Added SDIO_TX(DMA Stram3) and SDIO_RX(DMA2 STram 6) for DMA configuration.
3. SDIO(NVICSettings) -- then enabled SDIO global interrupt.

Again generated the code. With above changes FATFS mounting is successful.

And also I am able to read and write operations on SD Card.
