STM32F405 SD DMA only works once, no matter what

Hello,I am currently trying to get an Adafruit Feather STM32F405 board to write to files on an SD card using DMA. I'm using CubeIDE, not STM32duino, and I have tried DMA configurations with both a single stream and two streams (one RX and one TX). No...

Resolved! MCU type - Can one identify it?

Using something like STLink util or newer, command line software: Can one identify which type of STM32 MCU is connected? E.g. for use in further scripts. It doesn't help if I see it on a GUI somewhere.

Can it be possible to trigger DMA using a GPIO pin in STM32?

For my application I'm using a comparator and i have set a reference voltage(threshold) for that and my application is that, if the current passes through the threshold then my comparator output should be turn on(1 or 0). I have set the comparator ou...
