STM32G474E EVAL1 Demo SD Card issue

twinest · ‎2024-02-06

Hello,

I tried to execute the demo for the STM32G474E EVAL1 explained in this document : STM32CubeG4 STM32G474E-EVAL demonstration firmware - User manual.

But, I have an error when the board tries to display the pictures which are on the SD card.

I got " Error popup resource file missing please update sd card content".

I checked the SD card and my files are well in the right directory.

I tried with two different SD cards and I have the same issue.

When I checked with the debugger, I have the impression that is a problem during the initialization of the SD card during the call of SD_GoIdleState()

But now I have no idea to go further in my investigation.

So I search some help to solve my issue

Not easy to recover a broken SDcard slot. May be you need to clean it but it's risky.

Or buy add an external SDcard slot module like this one and wire it yourself:

PS: take care of the pull up resistors mounted on the module (see the image).

Which example you are running?

Which files you have stored on the SDcard?

Hello,

I run the example "Demo" when I choose my MCU in STM32CubeIDE in the tab "Example Selector" when I create a new project.

And I use the SD card provided with the evaluation kit and I checked, the files needed for this demo are well in the SD card.

The file system of the SD card is :

STFILES (with the bmp images used by the demo)

USER

STM32.TXT

Did you try the example provided in STM32CubeG4 under the path \Projects\NUCLEO-G474RE\Applications\FatFs as it is?

No, I tried only example provide for the STM32G474E EVAL1 because I have this card.

I will try this example

No problem.
So, yes I tried this example too and I got the same error

Hello,

For the demo located under Projects\STM32G474E-EVAL\Demonstrations did you copy the resources located under Projects\STM32G474E-EVAL\Demonstrations\Binary\SD_card to the SDcard?

Also are you sure the SDcard is well inserted on its slot?

Hello,

Yes, as I said earlier, the resources are well loaded on the SD Card, which is the SD Card provided with the board.

And the SD card is well inserted because I don't have the error related.

Like I said in my first message, I think the error occurs during the initialization of the SD card during the call of SD_GoIdleState()
