I am looking for some advices for my product using STM32U5G9 MCU with external QSPI Flash.
I want to create a bootloader for my product but I stuck at the approach how-to:
1. Can the boot loader support the external loader meaning also update the external flash data if there is any updates for my GUI information?
2. If the boot loader can't support the loading for the external flash, do I need to implement the external loader on the application layer?
Is there any application note for case#1 if it is possible?
Thank you so much for your advices.
