Porting project from NIOS to ARM

Hello,

We have a project in NIOS which uses controller in FPGA:

1. ethernet : TSE - triple speed ethernet, with iniche ip stack
2. UART
3. Flash (EPCQ)

We need to port the whole project to ARM.

This project also use uc/os OS.

We think it is just a matter of adding bridges to the controller in FPGA (for ARM HPS), and compile the project in DS-5.

Are there other modifications required which we should be aware of (in ARM DS-5 project, preloader modification , other ) ?

Thank you for any tip, suggestion,
