STM32H7B3I-EVAL + TouchGFX + FDCAN + "SD card"

[HJang.2]

I tried fdcan, touchgfx with stm32h7b3i-eval. I want to operate the SD card additionally, but it doesn't work.

Here are the ioc settings:

SDMMC1 -> SD 4bits Wide bus

FATFS -> check SD Card

If you disable "use dma tempate", it works, but if you want to use it with rtos, you have to enable it, but it doesn't work in this part.

f_open() returns FR_NOT_READY...

Please take a look at my project and point out the problematic parts.

thank you.
