Keil MDK Example Project: Relocate IVT and IRQHandlers to ITCM

Hello!

I am working on projects that mainly utilize the RT1062 or RT1176 MCUs (only M7 core).

There are conditions that would require the interrupts kept enabled while writing to flash memory.

This requirement prompts the need to relocate the Interrupt Vectors Table (IVT) from the flash memory to, say, the ITCM memory.

I have found good example(s) from various forum posts here that would outline the steps it needs to perform such in MCUXpresso.

I use Keil MDK for the toolchain and work on projects in Keil uVision. Would it be possible for someone to point me to a good example (project), ideally including Scatter File/linker script with all necessary changes to accomplish this?

 

This will be much appreciated!

Thank you!
