Hi all,
I would like to add on my project a custom bootloader using an UART.
In my project I have already an external QSPI loader used by TouchGfx to transfer the new graphic contents while programming my stm32h743 microcontroller.
This is my first experiment with bootloader on stm32 and I would like to understand how to implement a custom bootloader without deleting the external QSPI loader.
The scope is to use the Uart to save on QSPI memory the new fiimware and when all packets are correctly transferred on it and CRC result good, the microcontroller can start to update its FLASH memory.
Has someone a basic project for UART Bootloader?
(I wouldn't to use the bootloader Sw created by ST: I need to implement a custom protol).
Any kind of help is really apprecied!
Thanks in advance
MarcoP
