Is there a bug in STM32Cube_FW_F4_V1.27.1 or in STM32CubeMX?

I'm using STM32CubeIDE 1.11.2 and STM32CubeMX Version: 6.7.0.

I have a question regarding the implementation of the SDIO SD card in 4 bit mode on a stm32F407 card

I am using the following configuration

SDIO Global interrupt, SDIO_RX and SDIO_TX DMA

SDIOCLK clock divide factor 5

Unfortunately it doesn't work. The f_mount function returns an error (Error SD card) 

On the other hand if I replace SDIO_BUS_WIDE_4B by SDIO_BUS_WIDE_1B

line hsd.Init.BusWide = SDIO_BUS_WIDE_1B; as shown the program works.

Hello again @Abdelmalek BELLOULA​ 

Well, after some investigation, the bug mentioned in the thread is fixed in STM32CubeMX Version 6.7.0 which you are using.

In this case, I think the problem is the compatibility between the configuration (4B) and your hardware ( SD card) since you get error SD card

Thank you Sarra, I will proceed to check my hadware

I installed STM32CubeMX version 6.5.0, I generated the code with STM32Cube FW_F4 V1.27.0 I get the following code

and it works well and no error in the hardware I checked everything

on the other hand with the latest version of STM32CubeMX 6.8.1, I get the following code: and my program crashes

SO ?

Is there a bug in STM32Cube_FW_F4_V1.27.1 or in STM32CubeMX for SDIO?
