Hello @ram_jan 

This OpenBootloader application available in STM32U5 firmware package allows to use bootloader over USART3 or FDCAN1 or I2C2 or SPI1 or USB. I recommend reviewing the README file for detailed instructions on configuring it to use USART.

With regards

Hi Team,

Could you please guide me on how to modify the Flash starting address, Flash length, RAM starting address, and RAM length in order to organize the Bootloader and Application images in separate memory locations for STM32U585 Series ?

Hi Team,

Could you please guide me on how to correctly configure the internal Flash memory for the STM32U5 series? Specifically, I would like to understand how to:

  • Modify the Flash start and end addresses

  • Set appropriate lengths

  • Partition the Flash to allocate separate regions for the bootloader and the application image

Thanks and Regards
