Couple of things to keep in mind while using both the banks for your application:
1. Bank1 has an extra wait-state for fetch/read accesses. Hence, performance will be different than that of Bank0. Please map code that needs more performance
2. Do not use the last two 128-bit (16 16-bit addresses) locations in each bank. This should already be taken care by the linker cmd files provided in C2000Ware. When Flash prefetch is enabled, if the last two 128-bit locations are used, FMC will read beyond the implemented Flash size and can end up in ITRAPs/ECC errors.
Two banks are provided so that needed customers can use one of them for code and one for data. Also, users can maintain two images if they want for firmware upgrade reasons.
