Likely I mixed up the filenames when writing in conversation, as I did when writing on the opensbi mailing list about a dependency tracking bug in opensbi build system: https://lore.kernel.org/opensbi/[email protected]/ and https://lore.kernel.org/opensbi/[email protected]/ ...which is clearly a mistake to write "OPENSBI=/path/to/fw_payload.bin" when it should instead be "OPENSBI=/path/to/fw_dynamic.bin", acknowledged in the follow-up message: https://lore.kernel.org/opensbi/[email protected]/ > Could you clarify whether there is documentation (or a specific > requirement) that calls for fw_payload.bin in this flow?

If I mention otherwise it was in error or for not knowing what I'm looking at and reporting more information than required. There are RISC-V boards not related to VisionFive2 or its StarFive JH-7110 SoC that do use the fw_payload.bin approach but I think I just didn't notice the difference when transcribing to e-mail. > Thanks for your help and guidance. >> >> Best regards, >> Aristo > > Best regards, > Aristo Thanks very much for the follow-up, -E
