I am using the STM32H7B0VBT6 microcontroller, which has limited internal flash memory. To implement Secure Boot and Secure Firmware Update (SBSFU), I have connected an external W25Q256JVIQ flash memory to the MCU via Quad SPI.
Is it possible to store the bootloader in the internal flash memory and application firmware store into external flash memory? Please provide any guidance, documents, or articles to help implement this setup?
