I can't connect a SD Card to my STM32F072 Discovery Board

Hi all!

I'm trying to read/write data to an SD card from my STM32F072 Discovery board.

I configure SPI1 on CubeMx and the FatFs middleware. I've written the user_dsikio.c and the Input-Output functions based on the STM32F072 Eval board, but I can't make it work.

When I try to open a file, or format the SD, the microcontroller stops there and finishes at the Default_Handler, as I can see with the debugger.

Where can I find an example of a STM32F072 Discovery board with an SD?

Can anyone help me?

Thanks!!!!!!!!!!

Great!

So it's really incorrect SPI polarity setting? Could you mark it as 'correct answer'?

Yes! it was incorrect!

Of course, I will mark it.

Thank you!
