Hello All,
i want to implement bootloader in stm32g431rbt6 microcontroller using uart, I am looking for guidance and I would appreciate it if anyone could share useful resources, example projects, application notes, or tutorials specific to this MCU or closely related STM32G4 series chips.

Thank you in advance!

Best regards,

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Also consider using the built-in bootloader which is already supported by STM32CubeProgrammer.
