STM32303E-Eval SD Card

[DNA-)]

Hi everyone,

As part of one of my projects, I have to use an SD card to store my data. Since the final board has not yet been manufactured, I started developing my software on the STM32303E-EVAL evaluation kit.
For reference, it uses the same microcontroller that will be on my own board.

Back to the STM32303E-EVAL. When I received this board, the provided demo worked correctly (GUI display and so on).
I wanted to test the examples dealing only with the SD card (FAT32 format), which are available in the repository:
→ STM32Cube_FW_F3_V1.11.0\Projects\STM32303E_EVAL\Applications\FatFs\FatFs_uSD

Imported into CubeIDE, it does not compile, files are missing – in short, it is a mess.

So I started over from scratch, installed AC6, opened the project, flashed it, started a debug session, and I get stuck in f_mount().
The SD card is correctly inserted.

Could you help me?
Or, failing that, provide me with a working example?

Did you try to refer to the user manual UM2579 "Migration guide from System Workbench to STM32CubeIDE"

Hello,

Yes, I did it. I can’t manage to compile, but that’s not a big deal, I switched to AC6 instead.
The core of the problem, and what I don’t understand, is why the example doesn’t work in the project opened with AC6.
I really need this part to work so that I can move forward with the development of my firmware.

To be more precise, the code loops on:

/*----------Activates the card initialization process-----------*/
/* Send CMD1 (Activates the card process) until response equal to 0x0 and
Wait for no error Response (R1 Format) equal to 0x00 */
while (SD_SendCmd(SD_CMD_SEND_OP_COND, 0, 0xFF, SD_RESPONSE_NO_ERROR) != MSD_OK);

in stm32303e_eval_sd.c

The main problem was the size of the SD Card. 

The board came with a 32G Card which is not compatible with example.

Working with a 2Gb SD Card.
