We have an application running on a Wolf BL2600 (Rabbit 3000) compiled with Dynamic C 9.21. We would like to port this same code over to a RabbitCore RCM4300 series that uses Dynamic C 10.23. Is this something that can done within reason? In other words, how much pain would be involved? I expect some changes in mapping (memory, I/Os, addresses, etc.) but would the core code be able to remain intact or are major rewrites more likely?
