I don't know when I did the last u-boot update. At least I kept it when updating from 13.0 p-something to 13.1. However, in the meantime I did an update (with the arm64 package content) and now the screen stays black. Not sure when I will find time to investigate. At least I'm happy that I didn't update one of my Pine64 first. > Because the PMIC error looks like it's still in i2c mode and not in > RSB mode. > This was fixed in > https://cgit.freebsd.org/src/commit/sys/arm/allwinner/aw_rsb.c?id=12faeba9953ac7fa5198b258dcd80f89b3b4b947 > but it seems that I forgot to MFC it so 13.1 doesn't have it. > > The eMMC problem is likely due to the PMIC problem (we can't switch > the car to an higher speed as we can't change the voltage). > > I'm travelling right now so can't test if applying this commit will > solve everything. > > Cheers, > -- > Emmanuel Vadot <manu@bidouilliste.com> <manu@FreeBSD.org> > -- B.Walter <bernd@bwct.de> https://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
