Hello,
I have an issue: black screen and unreachable system after loading.

When loading is finished, I see login prompt, but after several seconds my screen becomes black and unreachable by SSH. PI power is on. It's not reboot or shutdown because in case of PI off - my monitor tries to search other sources. Also red light of PI is on and green light blinks time to time.

I have downloaded Release 8.0.2 2022-03-25, have wrote it by PI Imager. Set additional settings, related to network, ssh access and other (from Imager). First boot with resizing file system was done.

My PI is raspberry pi 3b v1.2.
Before I get black screen I can see started the system in the wi-fi network and can connect via ssh can ping. But after black screen I cannot connect to the system.
My connected hardware is usb keyboard and hdmi display. I tried disconnect HDMI monitor, but behavior the same - after some time, the system is unreachable.

By the way, I had under voltage issue before, but I fixed this issue. I installed Raspberry PI OS Lite from PI Imager, and LibreElec - both worked stable. Also I tried to rewrite sd card several times - any way the same issue. Several times installed Volumio - also worked.

In SSH session I see following info:
Code:
Linux: 11.2 | 5.15.28-v7+ #1532 | armv7l (32-bit)
Raspi:
Audio: Pi HDMI 1

may be related with this. I will try to catch moment, when the system freezes and check logs in this second...

Couple of news:
1) I found that system uptime in htop is 30 sec when the system ssh session is frozen.
2) I tried to switch terminal by Alt+F2 - It works!

So, now I have direct access via USB keyboard and HDMI display, next need to solve issue with network. It's strange, network works first 10-20 seconds.

I catched the moment when the system is disconnected by run `watch -n1 date` in ssh terminal, and last date I see is date of disconnection.

It seems I realized the issue: I have setup settings by RPi Imager, but boode setup guide says to work via Access Point. So I think my lost of connection is starting WiFi Access Point.
I will check it and write again..

06-01-2022, 06:07 PM (This post was last modified: 06-01-2022, 06:08 PM by TheOldPresbyope. Edit Reason: cosmetic fix )
Simplest way to start:
  • flash a fresh unedited copy of moOde image to uSD card
  • boot Pi from this card
  • wait some time for system to make various adjustments
  • if the Pi is connected via ethernet it will become visible on LAN with IP dynamically assigned by router and with hostname "moode". Enter http://moode or http://moode.local or http:<numeric IP address> in a browser on any computer connected to the same LAN and proceed to use moOde's WebUI
  • if Pi is not connected via ethernet but has onboard WiFi adapter it will eventually become visible as an access point with name "moode". You'll have to connect wirelessly to this AP from some host which has a WiFi adapter---smart phone/tablet/laptop/whatever. In this case, enter http://172.24.1.1 in your web browser on the connected host
Now you can configure as desired.

From the information you've posted it appears
  1. you expect moOde to use a locally connected display and keyboard as if it were just another instance of Raspberry Pi OS. It is not; it is meant to be an appliance with a WebUI, True, the WebUI can be reflected on the local display but only after this feature is enabled.
  2. you've partially configured the moOde image but incorrectly---don't edit the files in the image until you've read and understood what they do in this appliance.

In particular, I see this stanza in the moode.log you posted

Code:
20220601 190422 worker: -- Network
20220601 190422 worker: --
20220601 190422 worker: eth0 adapter exists

20220601 190422 worker: eth0 address not assigned
20220601 190422 worker: wlan0 adapter exists
20220601 190422 worker: wlan0 country (US)
20220601 190422 worker: wlan0 SSID is blank
20220601 190422 worker: wlan0 AP mode started
20220601 190455 worker: IP addr (192.168.1.12)
20220601 190455 worker: Netmask (255.255.255.0)

20220601 190455 worker: Domain  ()
20220601 190455 worker: wlan0 power save disabled
The IP addr (192.168.1.12) and Gateway () entries seem bogus.

Compare with this stanza I just clipped from moode.log of a Pi3B+ I just booted with no ethernet connection and no WiFi configuration
Code:

That's right I did wrong setup.

Currently I rewrote cdcard properly, without any changes from Imager side. Then loaded the system, connected to AP WiFi from my phone and configure.
