To migrate your existing embedded system from the Altera Nios II Classic processor to the Nios II Gen2 processor, you can follow the steps outlined in the user guide provided by Altera. Here are the key points to consider for the migration process:
1. **Hardware Migration:**
- Ensure you have Quartus II 14.0 or higher and Nios II Embedded Design Suite 14.0 or higher installed.
- The Nios II Gen2 processor family offers feature enhancements over the Nios II Classic processor cores, such as optional full 32-bit address space, improved Qsys interface, and more.
- The migration can be automated starting from Altera Complete Design Suite (ACDS) 14.1, or you can manually update using a migration Tcl script in ACDS 14.0.
- Make necessary changes in Qsys to replace the Nios II Classic processor with the Nios II Gen2 processor and regenerate the project.
2. **Software Migration:**
- Rebuild all BSP packages in the Nios II Software Build Tools projects after hardware migration to ensure correct information transfer.
- Ensure software modifications are made to accommodate new Nios II Gen2 features, such as peripheral memory regions or 32-bit addressing.
- Pay attention to software limitations regarding uncached memory regions and data coherency issues between cached and uncached data.
3. **Conclusion:**
- By following the guidelines provided in the user guide, you can successfully migrate your Nios II Classic embedded system design to the Nios II Gen2 processor with minimum effort.
- It is essential to update both hardware and software components to ensure compatibility and optimal performance after the migration process.
