Cannot connect via ssh protocol to orange pi 5b after installing sd card.

[Flops]

Suddenly after updating via armbian-config I lost ssh access and found the port closed. I rewrote the latest armbian version, stuck the sd card in, connected to ethernet cable via router and started up. The red and green lights were on as they should be and the internet cable was flashing green. Waited 3 minutes and checked the ports with nmap. And the port is closed again.
Not responding to ping at all. I am still new to this topic. Please help and sorry if the translator translates crookedly.

Sorry if this comes off as obvious or unhelpful... but if it were me I would hook up HMDI + USB KB real quick just to verify that the board was fully coming online.

Or do it properly via UART

Thanks for the answer. I'll give it a try. I do not have such an adapter, but I will buy it

In addition I want to say that when I tried to run armbian with usb ethernet started to light up and orange light. I am still waiting for the adapter to be delivered

I bought a uart and connected it according to the instructions in the video.
I used screen and set the speed to 1500000 but the terminal shows only garbage. Maybe I should set a different speed?

[Flops]

I use a CP2102 with UART Baud Rates: 300 bps -1 Mbps

CP2102

Good enough for allwinner but too slow for AML or RK.  Get a proper one. 1500000 is the correct speed. If the chip cannot handle it you obviously get an error or garbage.

[Flops]

ok. I forgot to look. All right, I'll buy a proper adapter. Can you recommend an adapter or tell me where to look?

aliexpress, amazon, ebay,.... all of those should have some proper ones. For recommended chips please refer to the video mentioned above.

[Flops]

Sorry, not paying attention

[Flops]

I bought it. I'll wait a month

[Flops]

I bought a uart and connected it as indicated in the video. The text is already readable, but sometimes it underwrites and moves away. What should I do next?

Modified: it does not output correctly what I enter. Is there any way to improve it?

Saw this in the logs:
INFOx4000001 != 0xfead0003
ERROR: INFO: BL31: Initializing Excervices
WARNING: No OPTEE providon. SMC`s destined for OPTEE wil (eMMC)
Maybe it means something?

[Flops]

No, it was just me being stupid and mixing up the wires.

[Flops]

The system boots from the sd card and correctly. sshd is also active. Strange...

[Flops]

It can work via uart, sshd works and yet it does not respond to a ping or ssh connection. At the same time it can connect to the internet and download packets by itself.

[Flops]

I tried rebooting the router. Nothing changed in the end. The router does not respond to ping, but the board works properly via uart. Please help

 

[Werner]

So when UART works you can use armbianmonitor -U to print debug output to serial and then use a pastebin service of your choice to share the whole output.

[Flops]

Could you tell me how to conveniently transfer logs to a text file, because the terminal floats when scrolling?

[Flops]

Here are the notes after the command

log

Either the logs are incomplete or the ethernet ports don't show up at all. Odd...

[Flops]

When I connected to cable and uart it was able to update and download packages. I will try to copy the log again today. And I'll also check ifconfig

This is what the ip a gave me when I plugged in the cable.

Edited February 4 by Flops

[Flops]

And yes, that log I sent you is without the cable connected.

[Flops]

Is there anything else I need to check?

[Flops]

When scanning the network via arp-scan it still writes (Unknown: locally administered).

[Flops]

Anyway, as it turns out I didn't have "local access" enabled in the access point settings. LOL
