Hi all, I use 2 STM32F446RE boards. They communicate with a CAN bus.I get a little code that allows my boards to enter boot mode when it receives a frame with a specific ID.When one enters in boot mode, using a third board, I send a frame with ID 0x7...
Hello,I am trying to enter the system memory at boot time with the STM32G030 MCU. It has the BOOT0 line shared with SWCLK functionality, which is new to me compared to the STM32F* devices. I always entered the system memory in other devices by settin...
