Thank you very much to take the time to write the reply.
Code compiled for the SAME70Q20B will run on the SAME70Q21B
That's a great news!
If you do intend to use that additional 1Mbyte, then you will at least have to change the linker script
I expected this, but that can wait for now. My goal for now is running the latest stable release on a custom board that I am in the process of building it right now.
If you need to enable in-app programming of the flash memory
Does the "in-app programming" required for anything related to the workflow of RRF?, or you are talking about flashing the firmware using in-app programming method?(I am a bit confused!)
But anyway, I think I tried this approach awhile ago by swapping all "SAME70Q20B" by 'SAME70Q21B" but failed to at linking stage but I will give a try later again.
I am software developer but unfortunately my experience with c++ and using eclipse is somehow limited (I am a Web developer) but I think I can manage to make the changes(it will be a good excuse to learn new things about eclipse anyway since I am a Visual studio guy)
Thanks again for your reply.
