How to switch the execution of the application code from external flash to internal ROM in STM32H7xx microcontroller?

Most micro-controllers just go wherever you set the Program Counter (PC), ie branch, subroutine call, function pointer, etc.

What external flash are you using? QSPI attached?

What are you actually trying to achieve? ie end goal.

We are using "SST26VF016B-104I flash", with QSPI interface.

Our final goal is to switch the execution from external FLASH to internal RAM on an interrupt.
