Dear friends,

I have an issue with uSD reading and writing in DMA mode (How ever I am able to read and write data on SD card when dma template is off). I used CubeMX to configure

♯

but it did not work for me ''out of the box''.

My CubeMX version is 4.25.0 and L4 MCU package is 1.11.0.

Could you point out what I am doing wrong in configuration or in my code or if it is CubeMX issue, could you please advice me how to solve it?

I found some topics related to SDIO and DMA configuration and tried to implement them :

Below you find screen shots with my settings and my SW4STM32 project including CubeMX file.

My MCU setup:

My CubeMX configuration:

1) Clock

2)Clock factor

3)NVIC

4)DMA

5)Pin configuration

6)FatFS (sector size)

7)DMA template enabled

Dear Imen,

Thank you very much for this notification. I just update my CubeMX immediately.

I have another question. Did ST MCU application team also fix bsp_driver_sd.c / stm32l4xx_it.c, because sources generated by CubeMX did not work out of the box?

I fixed them according to suggestions of

Kirshin.Evgeny

‌ and

Vasiliev.Alexander

‌ and upload the template to GitHub.

Thank you in advance for your response.

Best regards,

Dmitry.

Dear Imen,

I regret to inform you that even after upgrade to CubeMX 4.25.1 PLLM is still missing in the generated code.

Best regards,

Dmitry.

Hi

dmitry.kochubey

,

I tested with the attached project and the PLLM is well generated, could you retest please.

If you are asked to migrate your project please do it
