Am I correct in understanding that RVA23 is not compatible with RVA22, and therefore operating systems like Ubuntu 25.10 and 26.04 for RISCV64 only support the RVA23 profile? Does this mean that operating systems like Bianbu 2.2.1 and earlier, which support the RVA22 profile, should no longer receive software updates to the latest versions?
We will continue to enhance the competitiveness of the K1 product. Our current plan is to provide long-term maintenance for the Bianbu system based on Ubuntu 24.04. We will release system updates when customers encounter issues, when upstream updates become available, or when new features are introduced.

Thank you for your reply. But… you essentially only answered my second question. And you didn’t answer the first!!!
Are the RVA22 and RVA23 profiles compatible? Yes or no? Your answer will determine whether Bianbu 2.2.1 will also support the RVA23 profile or only RVA22, and K3 boards will require updated OS versions. Or will Bianbu 2.2.1 be compatible with any K1, M1, or K3 boards.
Code compliant with RVA22 can run on the K3 platform, which supports RVA23; however, Ubuntu 26.04 (built for RVA23) cannot run on the K1 platform, which only supports RVA22.
If there isn’t significant customer demand, the K3 will only support Ubuntu 26.04 and later versions, while the K1 will be maintained long-term based on Ubuntu 24.04.

Yes, I’ve already read that code created with RVA22 will also work on RVA23. That’s actually great. Less code rewriting is a good thing! It will make migration to K3 and RVA23 easier in the future.
That’s exactly the point I wanted to clarify. Thank you very much!!!
