TouchGFX conflict with SD card FAT system and not mounting (FR_NO_FILESYSTEM)

[EKari.1]

Dear Friends ,

I have an custom board that using STM32F746 + QSPI Flash (For LCD Data) + RAM (LCD Buffer) + USB Host FS + SD Card

Development tools :

CubeIDE Ver. 1.6.1       

TouchGFX Ver 4.17

And using Free RTOS

I want to use SD Card and USB Host for data storage (FATFS) , when I expand LCD pages by TouchGFX I meet problem with mounting the SD card !

By removing some page or light pages the SD card working without problem

The error that I see on mounting is FR_NO_FILESYSTEM !

Also I check when I remove USB host from FAT system the SD card works without problem .

Thanks everyone
