Flops Posted November 30, 2023 Share Posted November 30, 2023 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. 0 Quote Link to comment Share on other sites More sharing options...
Charles Lee Scoville Posted December 8, 2023 Share Posted December 8, 2023 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. 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted December 8, 2023 Share Posted December 8, 2023 Or do it properly via UART https://www.youtube.com/watch?v=UpVMO7gbnYM 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted December 9, 2023 Author Share Posted December 9, 2023 (edited) Thanks for the answer. I'll give it a try. I do not have such an adapter, but I will buy it Edited December 9, 2023 by Flops 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted December 9, 2023 Author Share Posted December 9, 2023 (edited) 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 Edited December 9, 2023 by Flops 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted December 18, 2023 Author Share Posted December 18, 2023 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? 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted December 18, 2023 Author Share Posted December 18, 2023 I use a CP2102 with UART Baud Rates: 300 bps -1 Mbps 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted December 18, 2023 Share Posted December 18, 2023 5 minutes ago, Flops said: 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. 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted December 18, 2023 Author Share Posted December 18, 2023 (edited) ok. I forgot to look. All right, I'll buy a proper adapter. Can you recommend an adapter or tell me where to look? Edited December 18, 2023 by Flops 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted December 18, 2023 Share Posted December 18, 2023 aliexpress, amazon, ebay,.... all of those should have some proper ones. For recommended chips please refer to the video mentioned above. 0 Quote Link to comment Share on other sites More sharing options...

Flops Posted January 14 Author Share Posted January 14 (edited) 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?

Flops Posted January 14 Author Share Posted January 14 Saw this in the logs: INFOx4000001 != 0xfead0003 ERROR: INFO: BL31: Initializing Excervices WARNING: No OPTEE providon.

Flops Posted January 14 Author Share Posted January 14 (edited) The system boots from the sd card and correctly. sshd is also active. Strange... Edited January 14 by Flops 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted January 15 Author Share Posted January 15 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. 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted February 3 Author Share Posted February 3 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 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted February 3 Share Posted February 3 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. 0 Quote Link to comment Share on other sites More sharing options...
Flops Posted February 3 Author Share Posted February 3 Could you tell me how to conveniently transfer logs to a text file, because the terminal floats when scrolling? 0 Quote Link to comment Share on other sites More sharing options...

Flops Posted February 4 Author Share Posted February 4 (edited) 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 Edited February 4 by Flops 0 Quote Link to comment Share on other sites More sharing options...

Solution Flops Posted February 25 Author Solution Share Posted February 25 Anyway, as it turns out I didn't have "local access" enabled in the access point settings. LOL 0 Quote Link to comment Share on other sites More sharing options...
