I need support to get IAP over SPI.
I've esp connected to my stm32u5 over SPI. Stm is slave and ESP is master.
For stm I've created project using stmcube by entering MCU part number.
Now here my question is
1. Do I need to develop bootloader code to achieve this.
2. How do I customise bootloader code.
3. STM boot pin is connected to ESP. do I need to control this?
4. Hwi do I adjust my memory or linker file
