Also, here’s what the display looks like while in nmtui:

Ok, but really sorry,right now I don’t have a clue

I used the uConsole_A06_v1.1e.img to verify the screen is garbled like yours, then use the
arch-linux-clockworkpi-a06-uconsole.img to boot up
it just worked like expected

I also checked the dmesg you uploaded, it seems just like mine,nothing particularly wrong
here is my dmesg.log

hey thanks for the image.. the display issues got resolved for me.

Now I am on tty.. and don’t know what to do.. Cos when i do ls .. it doesn’t list list anything!

For login i used alarm and for pwd i used alarm. Can i run a full desktop on this now? How?

24

good to know

and yes, it is a minimal os image, just a console
but it is an arch linux ,so you can install desktop after you connect wifi through nmtui

for example:
google archlinux install xfce guide

25

yes that is what is happening.. for some strange reason the wifi is not accepting password.. it also shows l0 as some available network.. Would you happen to know any workaround?

26

oh yeah, it seems so

the internal wifi seems not able to get a working connection

but then I used a usb wifi to get a working connection

sorry my bad ,did not run a fully testing

but right now ,I have no clue what is going on , I can see the wifi list through internal wifi but just not able to get it done.

I got it working

it seems a driver problem ,just append brcmfmac.feature_disable=0x82000 at end of
/boot/extlinux/extlinux.conf

like this:

[root@uConsole alarm\]# cat /boot/extlinux/extlinux.conf   
LABEL Arch ARM 
KERNEL /Image 
FDT /dtbs/rockchip/rk3399-clockworkpi-a06.dtb 
APPEND initrd=/initramfs-linux.img console=tty0 root=LABEL=ROOT_ARCH rw rootwait audit=0 brcmfmac.feature_disable=0x82000

then reboot

It worked.. And the wifi is working. So it is online. Glad that it is.

Thank you for saving the moment.

But will wait for the official distro to roll out.. since there are a few caveats.. like it sleeps and fails to recover.. keyboard lights, etc. Hope Clockwork responds soon.

Continuing the discussion from LCD garbled on new uConsole with A-06: Thanks for the Wifi fix.. BTW do you happen to know the way around the Audio fix. There is no Audio and i’ve been googling to get it up and running, but no sound yet.
