Problem with SDMMC2

[JEAN_121188]

Hi!

I'm trying develop code with STM32H745IIT using SDMMC2 in M7 core based in this tutorial:

https://www.youtube.com/watch?v=I9KDN1o6924

My version the CubeMX is: 6.17 and STM32CubeIDE is 2.1.0

Initially I set mode: SD 4 bits Wide bus and configuration is:
NVIC: Enabled

NO constants

GPIO Setting:
- PB3: D2, PB4: D3, PB14: D0, PB15: D1, PD6: CK and PD7: CMD

- DMA: not exist??

Only with this code is the following error generated in CubeIDE:

(HAL_SD_Init): Unknown destination type (ARM/Thumb) in ./Application/User/Core/main.o
(HAL_SD_IRQHandler): Unknown destination type (ARM/Thumb) in ./Application/User/Core/
undefined reference to `HAL_SD_Init'
undefined reference to `HAL_SD_IRQHandler'

Any sugestion?

Thank's

Hello @JEAN_121188 

Is the macro #define HAL_SD_MODULE_ENABLED is defined in stm32h7xx_hal_conf.h. If this define is missing, the SD HAL APIs such as HAL_SD_Init() and HAL_SD_IRQHandler() may not be compiled correctly.

Are those the only errors ?

Specifically, are you also getting dangerous relocation: unsupported relocation errors ?

If so, see this thread.
