Resolved! STM32H7 UART TEACK forever after clock switch

Hey together,I discovered a super strange a critical behaviour of the STM32H750 chip. Maybe you can help me to prove this issue. We have a firmware which is split into 2 parts (bootloader, application). Both BL and APP are using the UARTs to communic...

Flashing issue using Zephyr & STLink

Hello,We are migrating to zephyr, the board which is supported by zephyr is nucleo_g0b1re, but out actual controller is stm32g0c1ret3. Both are of same family, have same memory and all. I have just made changes in the overlay file for my application,...

Resolved! Setting GPIO interrupts for two identical pins

We are developing a software application that uses GPIO interrupts.We want to set interrupts on the same pins (PE8, PG8), but only one of them can be set to external interrupt mode in the ioc.Is it not possible to set external interrupt mode for two ...

Resolved! Is it a bug? STM32F0xx HAL USART Driver

 Hello All,I am using USART peripheral to transfer a block of bytes. I am trying to do it using DMA. Because I want all bytes of USART frame should be dispatched without any gaps between them and my system has few interrupts that could bring gaps bet...

Resolved! Hello, I'm having troubles changing the baudrate of my UART2 configuration. It is initially set to 921600 bps and a bit duration is 1.08us = 1/921600bps, which is fine. However, trying to double this value seems impossible.

In MX, at first, I changed the sample rate to 8 bits to double the baudrate. The code was successfully generated, compiled and downloaded. The communication still exists, but the baudrate is still the same as before, with a bit duration of 1.08us.The...
