Why does I2C get stuck with HAL_BUSY state?

Hi, I am trying to read MPU6050 FIFO data with STM32F103C8T6 after I get an interrupt from MPU6050. All works well at start, but after some time I2C gets stuck with HAL_BUSY state and never recovers from it. Here is my code:void HAL_GPIO_EXTI_Callbac...

Why would I see different results writing data via the FMC while debugging with a breakpoint on the enable step compared to running without breakpoints? With the breakpoint, I get valid data.

I'm using the FMC of a STM32H7 micro to communicate with an LCD, which has timing signals similar to a NOR SRAM. I have the MDMA configured to write 16-bit words out of a buffer to the FMC at the 0x60000000 address (bank 1). The MDMA is configured to...

Resolved! STM32F746 "forgets" flashed program (and more)

I migrated to a new self-created PCB with a STM32F746IE. I noticed that if I flash anything, the program works immediately after flashing, but not after power off/on. As a simple example, I created a program with two blinking LEDs. They blink after f...
