Hi E Shattow, Thanks for the review!
I agree with Yao and Hiago. The sys prompt, build steps and documentation match the existing milkv_duo and milkv_duo_256m support, so I'd like to keep the Duo S the same (at least for this series). If any of these changes are needed now, I will send a v2. I also agree that better documentation for the OpenSBI version requirement, the FSBL and fip.bin (with links to the vendor sources) is needed, but that applies to all the Sophgo boards. I can send it as a separate series later if the maintainers agree. > -E Shattow Best regards, João Paulo Gonçalves
