Migration from Cortex M4 to Cortex R5F

AakashKedia22

Hi Champs,

I intend to migrate from Cortex M4 to Cortex R5F. As I understand both the CPUs seem very similar in a lot of aspects MPU, instruction set and yet is very different from the other. I am using ARM-CLANG as a compiler so I am not worried about the instruction set.

I would like to know which are the major points where I would have to change my software like interrupt handling, startup (maybe ?), systick handling.. Can I get an overview with this information ?

Best Regards,
Aakash
