Unfortunately while I can readily look around and identify things that mention "usb", "ehci", "ohci", and "phy" in ofwdump output and in *.dt* files I've no clue about u-boot, *.dt* 's, and the like --and very little clue about the kernel. It would be more of a from-scratch research project, much like finding that "dts ish" before "sev" would, for example, again allow the Pine64+ 2GB to boot from a modern non-debug kernel. That was a lot of exploration to find a single instruction to add. When I started I had no clue it would end up as something like that. [Sometimes when I explore like that someone with the proper background picks out what the core issue is and how to fix before I get as far as a likely suboptimal solution that points in a very specific direction. Other times I get there first.] So if an BPI-M3 u-boot update waits for me it is likely to be a significant wait. Someone with more background likely would work better. Hopefully I'd be able to test trial updates since I have a board. For now it looks like I'll need to set up a non-USB configuration to progress to modern head. >>=20 >> The BPI-M3 has usb nodes show in ofwdump. . . >>=20 >=20 > Yeah I miss-read the DTS because 4 of them are used for one board ... > I don't want to update the dts in sys/boot/fdt/dts/arm and I will > remove them soon.
