The function HAL_RCC_DeInit() in STM32G4xx_HAL_Driver/Src/stm32g4xx_hal_rcc.c contains the following: /* Clear CR register in 2 steps: first to clear HSEON in case bypass was enabled */ RCC->CR = RCC_CR_HSION; /* Then again to HSEBYP in case b...
I've noticed that these a lot of differences between what was spoken in the presentation and what we were told to enter in.ie:osThreadId Task1Handle;osThreadId Task2Handle;osMessageQId Queue01Handle; <--- exampleosThreadId_t Task1Handle;osThreadId_t...
I had FDCAN working on the G4 MCU before doing the firmware update from 1.0.1 to 1.1.0. Since the firmware update and upgrade from STM32CubeIDE 1.0.0 to 1.2.0, the FDCAN controller seems to not transmit any messages, even though the HAL_FDCAN_AddMess...
Hello ST-Community!I am having a very rough start with my first project using an STM32 MCU. My task is actually very simple and I was confident I could fit this in 8kb of program memory. It actually fits the flash in release build, but I cannot debug...
Hi,Why it is required (or recommended, as I see in examples) to set the link down when the cable is plugged out from the ethernet connector? It works when I once set the link up and leave it up forever. It doesn't matter when I plug out and in the ca...

I worked on ethernet in NUCLEO-H743ZI2 and it was working properly. But when I developed my own PCB and used the same ethernet circuit as nucleo board, ethernet connection is not even detected.
Hi STM,I am using STM32F4 I2C with DMA as a slave device.I found that the below snippet of code in I2C_ITError function (stm32f4xx_hal_i2c.c, line 6146) assumed that if hdmatx is not in HAL_DMA_STATE_READY, then it must be hdmarx in HAL_DMA_STATE_REA...
