CubeMX V4.24 with FatFS R0.12c problem to work with SD card when FreeRTOS is present

I am trying to use the latest CubeMX V4.24 with FatFS R0.12c, I am using FreeRTOS in my project. The SD card is connected using SDIO 4-bits wide bus. The MCU is STM32F427. HAL driver is V1.19.


The problem is that f_mount function is never working. Seems that a response from queue never comes in function SD_read from sd_diskio.c file:

event = osMessageGet(SDQueueID, SD_TIMEOUT);


I was able to make f_mount work OK by applying suggestions described in this post, which refers to CubeMX V4.23: STM32Cube_FW_F4_V1.18.0 + SDIO + FATFS R0.12c doesn't work, however now creation of a file does not work.


Can you suggest anything?

P.S. I know that when there is no FreeRTOS present operation with SD card is working well as provided in examples of CubeMX.
