Netbsd on rock64 with no SPI

kc9udx

rvp well, it depends when it was added and when the production U-Boot was generated. But it does look to me like it's been there a while 🙁

hea please do let me know if you are able to extract and use that U-Boot

Struggling again. Trying to mount the image to get access to the creds.txt file... want to at least access the card via ssh before trying any further:

# vndconfig vnd0 ./NetBSD-10-aarch64--rock64.img
# vndconfig -l /dev/vnd0*
vnd0: / (/dev/dk0) inode 1547380

looks like it should?

# mount /dev/vnd0a /mnt/image
mount: no match for vnd0a: No such process

Tried some variations of this but new obstacles round every corner :-(

~~hea shouldn't you be trying to mount /dev/dk0 or possibly /dev/dk0e rather than /dev/vnd0a?~~. I'm prolly wrong, I have no idea.

hea that sounds like I ran into a file size limit. But I'm pretty sure I checked for that. I'll have to see later when I get a chance. Possibly I'll send the file separately.

You should also be able to mount the wedges on the SD card directly with their device names.

@kc9udx : I get this when renaming file to u-boot-2022.01.tar.gz and trying to tar xvf

x rock64/ x rock64/idbloader.img x rock64/installboot.plist
x rock64/rksd_loader.img: Truncated tar archive detected while reading data: Unknown error: -1

Lo and behold! I have now logged into this computer for the first time via ssh. I manged to copy a creds.txt file to the msdos partition. Being spoon fed for almost a week I'd better make it work...
Thanks for all your help! This is really unknown territory for me and the information one can find often demands some extra knowledge that I don't possess, so this has been lots of learning and very enjoyable:-) I think I need a break before trying the modified u-boot. ssh access is at the moment sufficient on this computer but I will try to see if I can get the display working...

hea if you haven't already, make sure to download those files from termbin; before they expire and get deleted. They only have time-to-live of one week.

hea

kc9udx Are the files compressed?

hea

Thanks! I downloaded straight away. Not ready to try it yet. The network behaves weird on the rock64. Need to be connected directly to router. Do not accept switch connection. So amongst other things I'm trying to sort out that.

kc9udx

FWIW I've had 10/100 or even 100/1000 switches that refuse to link up with certain 10/100/1000 devices. In my cases, it has always been the switch at fault.

kc9udx

hea ~~I think so... but not certain at this point. I might have tarred them with -z.~~
They're gzipped. You must gunzip them before dd'ing
