The latest version (5.4.0) of CubeMX (and who knows... maybe every version before) generates DMA initialization code out of order, and it's kind of hard to diagnose until you single step through all the HAL code.I am using an STM32H743 and setting up...

Hello, I'm attempting to use the SDMMC with an SD card, and with DMA. However, when I use the STM32CubeMX IDE, there is no option to enable or use the DMA. Using: STM32CubeMX version 5.3.0Here's the configuration for SDMMC1 on the STM32H743And here i...

Hello, I am attempting to use all 4 sai ports as one large synchronous audio device.The I want SAI1A to be the master, and SAI1B, SAI2A, SAI2B, SAI3A, SAI3B, SAI4A, SAI4B to all be synchronous slaves to the SAI1A.I am able to configure them all, exce...

Hi again, I'm attempting to use the I2S peripheral on the STM32H7, and the CubeMX produces half-duplex code. Here you see that I'm using an STM32H743, selected I2S, full-duplex slave, but the only choices of mode I get are Mode Slave Transmit and M...

I had a board that I was debugging, and all was going swimmingly. Then I started getting an 'unable to connect' message while debugging. I didn't touch the hardware, nothing had changed. So I thought.To make a long story short, I had enabled the f...

I haven't gotten to the I2S yet, just the SAI so far. Got pulled to another project. Are you sure that you understand and have dealt with all 3 issues I mentioned above? Namely: If the reader ended up here because of DMA not working with CubeMX,...

So, not just me :)

Ah! I found the secret, magic buttons that allow you to re-order the functions calls. First of all, the tool should always put DMA first so that the generated code can work. However, you can, if you like, change the order of function calls by doin...

This is the one that works for me. But rather than copy into the current workspace, I just link over to the ~/STM32Cube files. Thanks for the answer.
