I use FREERTOS and UART and my info in COM port is breaking

I want the information in one thread to be processed, and the second thread to be sent via UART. I made a small template where I send pseudo data via UART. But my information does not come in the right way. I think it has to do with interrupts. I use...

STM32G071RB Nucelo board - Can't access MCU via SWD or Serial Bootloader

HiWe have an application where STM32G071RB are used and can only be programmed via ST's Serial Bootloader. That works fine but after 1st programming, we realised that the Boot options bits in the Userbytes of the Flash memory need to be configured co...
