I just receive my N2 and 16GB eMMC (with Linux).
I downloaded the image for N2, flashed with Rufus and tried with Etcher too, and Librelec tool. Flashing went fine always. I even copied the Device Tree (tried a fresh install without that) and no go.
N2 boot up fine, I have the Hardkernel logo, then CE is saying resizing partition and reboots. After that, not working. I see the HK logo, than HDMI no input message. I really tried many-many times to flash the eMMC, same. Also, I tried an mSD card, no help - the same.
Leaving it on for some time (few minutes), the HK logo comes back and stays there.
Any ideas how could I debug this or what could I try?
(I tried the SPI switch as well. Set to SPI, it displays the booting, etc, but after just blank screen).
EDIT: after countless number of reinstallations, I switched to HDMI port 2 (with ARC support) on TV and it started working. Don’t ask why and how. I did update SPI to newest version from HK, but on the same HDMI port it didn’t help. Now running fine. I hope it will stay like this.
Sure, it is Panasonic 65gx800.
And after working perfrectly fine since yesterday afternoon (after switching to HDMI2 input on TV), now in the morning I switched on the telly and N2 is not working again. The same problem. Restart doesn’t help, Hardkernel logo on boot, and than nothing, blank screen, no CE logo. After a while it returns to HK logo and stays there.
Is there anything I can do? What can be the problem? Maybe setting something in CE config?
Edit: maybe to check somehow the logs? But I can, as the n2 doesn’t boot to CE even if hdmi is disconnected, so no ssh, nothing.
OK, after trying again and numerous power cicles, N2 booted from eMMC.
I turned on debug logging, and here are the logs. log-2020-08-10-10.14.08.zip (113.7 KB)
I hope there is at least something in the logs that might help.
Strange is, tha leaving it off for a while, then turning it back again, it didn start. And again, after several power cycles, it works again. What a hell can this be?
OK, I will try again with SD card. I did try it many many times before.
It starts with both red and blue light, but after Hardkernel logo (when CE should start) it just stops and only red light is on. No blue light blinking.
PSU is a Chinese 12V4A psu. Maybe the PSU is the problem? But now at the moment it is working. I did several reboots and fine. If it was a bad PSU than it would not work. Or not?
Big MAYBE.
Both Red and Blue lit is correct behaviour.
No it will do what your’s is doing.
Piss it off and then you’ll have peace of mind.
If you have peripherals plugged into the USB ports it will be worse.
12V/5A? The shop is sending me a 12V2A PSU and Odroid uk is selling N" Coreelec edition with 1,5A PSU. My friend ordered from them a year ago, and it is working perfectly fine since then.
So I got the new 12v2A PSU, and things look perfect. I will see by end of the week, but it works, boots as it should. Strange thing is that the apparantly faulty psu is also a mid quality one. It was sooo irritating.
Btw, should I update Petitboot to latest (using emmc for CE) or it doesn’t matter at all?
Many thanks for helping me troubleshoot this issue.
You need Petitboot only if you wish to use different operating systems, i.e. CoreElec on eMMC, Android on uSD card and Ubuntu on USB drive. If you use only one than you have no need nor use for Petitboot.
