STM32G4 bootloader via canbus

PedroLuis · ‎2024-02-26

Im trying to bootloader my firmware in my nucleo G431RB vía canbus with a StLink v3 set, its posible?.

In An2606 says there is no opción.

Do i have to write the bootloader ? And with that i will be able to load vía StLink v3 set?

Hello @PedroLuis and welcome to the ST Community 😊.

For the STM32G431RB, the only hardware ressources that can be available are USART, SPI, DFU and I2C. CAN is not available for bootloader. Look at the AN2606 and the product datasheet.

Best Regards.

Hello,

Indeed no bootloader over CAN bus. See AN2606 / Table 99. STM32G431xx/441xx configuration in system memory boot mode.
