[PROBLEM] Unreachable SSH and HDMI black screen after loading OS.

[TheOldPresbyope]

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 wait for address (No)
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: Gateway ()
20220601 190455 worker: Pri DNS (127.0.0.1)
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:

20220601 131611 worker: -- Network
20220601 131611 worker: --
20220601 131611 worker: eth0 adapter exists
20220601 131611 worker: eth0 wait for address (No)
20220601 131611 worker: eth0 address not assigned
20220601 131611 worker: wlan0 adapter exists
20220601 131611 worker: wlan0 country (US)
20220601 131611 worker: wlan0 SSID is blank
20220601 131611 worker: wlan0 AP mode started
20220601 131644 worker: wlan0 wait 0 for IP address
20220601 131646 worker: wlan0 wait 1 for IP address
20220601 131648 worker: wlan0 wait 2 for IP address
20220601 131650 worker: IP addr (172.24.1.1)
20220601 131650 worker: Netmask (255.255.255.0)
20220601 131650 worker: Gateway (0.0.0.0)
20220601 131650 worker: Pri DNS (127.0.0.1)
20220601 131650 worker: Domain  ()
20220601 131650 worker: wlan0 power save disabled
