sdcard not working in freertos when using with sdio

[TTa.1]

Hi all, I have had some problems when working with sdcard (using sdio) in freertos. I use dev kit STM32-E407 Olimex ( it support sdcard slot on board, I use sd card 16GB). when I read sdcard without using freertos, It's working. But when I using freetos, f_open return FR_NOT_READY (I read sd card outside thread). Please explain me what's reason and I can read sdcard (using sdio) outside thread when using freertos ? Below are some configures in my projects.

Hello @TTa.1​ ,

Take a look at the following example provided under our F4 Firmware Package (path: Projects\STM32F413H-Discovery\Applications\FatFs\FatFs_uSD_RTOS)

Use it as inspiration. It may help you.
