TheSHAD0W Posted July 4 Share Posted July 4 (edited) Armbian 24.5.1. I don't have a serial console setup so I can't tell if it's actually starting to boot or not, but it never gets to the point where a video signal is sent to HDMI. It *does* send a CEC on signal to the TV, which does turn on, and power-cycling the Pi then begins a normal boot process. Pi also boots normally headless. Problem noted on one Insignia model and on a Vizio TV, works as expected on another Insignia model, on a Hisense and on an LG. Issue began after updating the kernel from legacy.

Werner Posted July 4 Share Posted July 4 You seem to be the first person reporting such an issue and none of us has a second sight. Therefore without logs there is pretty much nothing we can do. 0 Quote Link to comment Share on other sites More sharing options...
TheSHAD0W Posted July 4 Author Share Posted July 4 (edited) https://pastebin.com/2WpTQy3G last 500 lines of syslog. I'll try to get a debug console working but it may be a while... Note that last boot was actually two boot attempts, one with the TV off, and it doesn't look like it sent anything to syslog.

TheSHAD0W Posted July 6 Author Share Posted July 6 (edited) Okay, found another klew to this issue... Apparently the pi is outputting video at a default 4K spec, and most of the TVs I'm using aren't accepting it, but one is.... Multiple lines of: Quote begin: Running /scripts/local-block ... done. Then: Quote done. Gave up waiting for root file system device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/nncblk0p1 does not exist. Dropping to a shell! I would have played with the shell, but the machine is way up on a wall, and I had to transcribe the above from a photo of the screen. ^^; Edit: And yes, I triple-checked the issue only pops up when the attached TV is turned off.

TheSHAD0W Posted July 17 Author Share Posted July 17 Allow me take this opportunity to thank Rockchip for choosing a default communications rate that so many TTL serial adapters can't reach. New adapter on order that can do 1.5 megabit. Like 1 megabit isn't fast enough. Or even 115,200, for a text terminal. 0 Quote Link to comment Share on other sites More sharing options...
TheSHAD0W Posted July 25 Author Share Posted July 25 (edited) Okay, after beating on things I now have log captures from debug console for both successful and unsuccessful boot. tvonoff.zip Edit: Most recent release kernel does not fix the issue. Edit 2: LOL why do these files show up as corrupt (or Chinese) in a gui text editor? Edited July 25 by TheSHAD0W 0 Quote Link to comment Share on other sites More sharing options...
