Does SD work with CubeMX 5.6.1? (STM32F411/STM32F412)?

[MarieMaurer]

I have found an old video

https://www.youtube.com/watch?v=0NbBem8U80Y

telling CubeMX 4.24 and 4.23 had a bug with SDIO, 4 bit mode, DMA.

It seems for them 4.21 worked.

I am using newest CubeMX 5.6.1. When was bug fixed? I assume it was fixed also in version 5.6.1?

I first started on a STM32F412, meanwhile on a Nucleo Evalboard with STM32F411,

but I can't seem to be able to access SD card. I see CLK line toggling. I see bits on CMD

(recorded with a logic analyzer)

but can't interpret them. I assume SD card is not answering at all, because makes

not much difference if card is in or not. It is a 32GB uSD.

I have no pullup. Do I need (external/internal) pull ups to get it working?

I want to work without interrupt, and also without DMA, to make it easier.

Is it possible? Is looks like I can't disable "Use dma template" in FatFS dialog.

I don't have a detect pin, just select no pin and ignore warning.

I can't switch power, 3.3V for uSD card is always on. Is this a problem?

Does someone have a working project with source code, so I can adapt, try out and compare? I can use STM32F411 and also STM32F412, but with first one I am more flexible.

I am using arm-gcc in WSL with latest Ubuntu.

Dont know if helpful, this is what I logged out:

Generally the way the forums work, we only hear bad news. If I believed the forum I'd assume nothing with CubeMX worked properly.

Polled operation on the F4 should be viable. DMA should also be viable, needs 32-bit (4-byte) aligned buffers.

Should be several working examples for EVAL and DISCO boards in the CubeF4 repository, often in the Applications\FatFs directories for boards shipping with SD card sockets.

Pull-up of data/command pins at the socket is generally recommended. Lacking them I'd use the internal ones.
