I've been attempting to get 7.8 installed on this unit and have some
observations and problems. Any pointers welcome.
With some help from ChatGPT I successfully built u-boot-rockchip.bin on
both a Ubuntu 22.04 and an OpenBSD 7.8 (on a apu2 box) system by download
of latest githup RK3528 information.
Following the instructions for arm64/INSTALL.arm64 I built a microSD
card and was able uboot and bring up the install from miniroot78.img.
I got the option of either sd0 (the emmc card) or sd1 (the microSD card)
so tried sd0, but ended up with not being able to write the disklabel:
here's what I got then:
sd0*> p
OpenBSD area: 0-61554688; size: 61554688; free: 2097176
# size offset fstype [fsize bsize cpg]
a: 55499552 6055136 4.2BSD 2048 16384 1 # /
b: 3957960 2097152 swap
c: 61554688 0 unused
sd0*> w
disklabel: DIOCWDINFO: Input/output error
disklabel: unable to write label
It may or not be relevant that the e20c has the radxa debian image
installed - it will boot this in the absense of the micorsd card.
Also, I cannot get to maskrom. The sequence outlined in radxa instructions
does not work now that the debian image is installed.
I then installed on the sd card, but 1) am unable to do anything with sd0,
2) do not find both ethernet ports.
I'm connected from my ubuntu box with minicom. Here's a reboot showing
the u-boot and dmesg for startup. At the end is what I find with disklabel
sd0 - it's consistent with my install problem.
