Clockwork uconsole cm5 horizontal lines on screen

uConsole

uconsole_cm4_v3.0_64bit_cm5_test2.img.7z

Finally I got a working image with my new arrived CM5 lite + 8G ram version

the first thing is the boot problem

If you plugged uConsole+CM5 with HDMI cable,then you will see normally the first time RPI cm5 reported

SD card not detected

then I waited about 1 minute, suddenly CM5 got booted…

And it turns out that ,this is the problem with eeprom config,see Rex’s thread

but never mind ,finally you will get into cm5 to get eeprom configed

About the screen problem:
In the test1 img, actually it can work
just remove spi related lines in /boot/firmware/config.txt

since the newest lcd screen use GPIO 8 to be the id_gpio

GPIO 8 is also the SPI0 CE0

so that is why screen can not be turned on

in dmesg it shows:

[    4.221720] panel-cwu50 1f00130000.dsi.0: failed to request reset GPIO (-16)
[    4.221726] panel-cwu50 1f00130000.dsi.0: probe with driver panel-cwu50 failed with error -16

so in test2 image ,I edited config.txt as below:

dtparam=spi=on
dtoverlay=spi0-0cs
gpio=10=ip,np
gpio=9=op,dh

to avoid ce0(gpio8) conflict

I am not sure other CM5 type will work as we expected, but I think HDMI is a real necessary tool to debug

I can confirm that. Downloaded the test image, flashed it and Display is working now. I also don’t have the audio crackling sounds anymore.

Hello guu, after installing your new image, the uconsole is usable, sound works, display works, USB port works. I only have problems with the on/off switch. After every shutdown, I have to remove the batteries to be able to restart.
Thank you very much for your work.

I’ve tested on my uConsole+CM5 with shutdown couple times, it’s ok,no need to remove battery

just have once hanged during shutting down

But I am ok with this result,since CM5 is not officially supported by CPI yet, official CM5 support board will come out soon.

So if your uConsole is new ,then this every shutdown battery remove situation should be a after-sales issue

try send email with details to alex@clockworkpi.com for further help

New Uconsole motherboard in the pipeline?

@guu Next week, I will receive the NVMe battery board from hackergadgets. Then I will install a battery disconnect switch in the case. It seems that many uconsole CM5s suffer from this problem. I won’t bother Alex from clockworkpi about this, as they are surely aware of this issue.

I had the same issue and the test2 image works perfectly, Thanks guu!

How can I modify the other distro images from Rex to work as well? I tried to use the same kernel as the one in the test2 image with the screen patch and modified the config.txt as described but it seems not to work.

I will be updating my images this week.

Whats this about a new screen ?, do we know the specs/changes and how to tell which we have ?

the specs are the same, it’s just minor differences in the driver
