Does it have proprietary firmware?
- rwmj 5y agoThe boot sequence is described in section 2.2 of this document: https://starfivetech.com/uploads/hifive-unmatched-sw-reference-manual-v1p0.pdf https://starfivetech.com/uploads/hifive-unmatched-sw-referen... And some more detail here: https://u-boot.readthedocs.io/en/stable/board/sifive/unleashed.html https://u-boot.readthedocs.io/en/stable/board/sifive/unleash... The flow is something like: ZSPL -> uBoot SPL -> OpenSBI -> uBoot -> kernel Everything is open source except (maybe?) ZSPL which I think is stored in ROM and just loads the SPL off the MMC card.
- gnufx 5y agoThanks -- good to know. I think I'd seen that on the boot process but didn't know about what's involved.
