Odroid N2 CoreELEC 9.2.2 not working


Unfortunately release 9.2.2 is not working on my Odroid N2.
Update from 9.2.1 ended in something like a kernel panic when rebooting.

New installation of 9.2.2 did the same.
I used device tree g12b_s922x_odroid_n2_dvb.dtb for the new installation.

Sorry, cannot provide more information, I need the box therefore I
re-installed 9.2.1 from CoreELEC-Amlogic-ng.arm-9.2.1-Odroid_N2.img.gz

Is there a reason you are using that device tree rather than the default one?

My first try has been just start the update from the running 9.2.1. After ending in the kernel panic on restart I tried a fresh install. From the install guide I selected the device tree odroid-n2 with dvb-t:
That seemed to be the best choice for Odroid N2 with DVB-T2.


I’m seeing problems with my N2 and 9.2.2. In my case, boot loops, but i’m not sure it is related
I will run an image of stable 9.2.1 to see if it persist.

EDIT: Can’t find stable 9.2.1 anymore. Will try a few more tricks to see if it works fine

g12b_s922x_odroid_n2_dvb is only for when you have a DVB adaptor attached via GPIO not when you have one attached via USB.

Do not use the bottom USB port next to the DC jack.

O.k., thank you. I’ll try the other device tree. meanwhile I checked which device tree my 9.2.1 installation uses. It’s the non-DVB variant.

My DVB-T devices are connected to the MicroUSB port using a powered USB3-Hub. I have had many problems with one of the USB3 ports of the N2.

Downloads of rel. 9.2.1:

Thanks a lot.
What i finally did was flash the 0413 nightly, disable updates and block traffic from coreelec to internet. It is working fine. Restored a backup I had, updated with trakt and is all up and running.

I’ll wait a few days (weeks) to see if the 9.2.2 situation gets solved. Meanwhile, will be d/l these images onto my nas, just in case

Sticking to old images is the way to get in trouble in the future. Just sit and wait for some problem to be solved with the help of others is not way we would like our community to work. But everyone is free to do whatever they want.

I already told you how to solve the issue.

I’m very sorry @adamg, but I must have miss your answer on how to solve the issue. Please be sure that if i see you provide a fix, i would try it first thing instead of running an older build.

Going back on your answers, i see you have answers for joche02, but not one for me. Maybe your answer was for both of us?

What is reason for this issue? I am using all usb ports on my device. Any ETA for the solution?

In my installation it’s an issue with connecting DVB-T sticks to the type A USB connectors. Did not really test all 4 jacks in a structured way but will do it soon.
Btw.: Yes, I connected my DVB-T sticks using a powered hub.

The issue are USB 3.0 device on both ports (top & bottom) next to the DC plug.
USB 2.0 or lower are working fine.

I currently searching how to fix this properly.

Tried it again using a fresh installation with the non-dvb device tree. The “oops” appears after showing the Hardkernel logo.

I took a photo and did OCR:

If you like to see the original photo, I need to know how to attach a PNG file.

Do not use the USB port at the bottom next to the DC jack.

Do not use the USB port at the bottom next to the DC jack.

I don’t know if it’s an answer to my posting of the stack trace. Just to clarify: DVB-T2 sticks do not work reliable connected to the USB3 ports. They are connected using the MicroUSB jack.

I did not change it with the update to 9.2.2.

Ok. Will try this on 9.2.2 and report back

EDIT 20200415: All is working fine now. v9.2.2 up and running

Can anyone tell me how to boot another image from SD whilst CE is on emmc? Odroid UK have said this isn’t possible and removing the emmc will void warranty.
I’m sure I read on here you can dual boot 2 images from same emmc but I can’t find where I read it.
Just booting from SD and leaving CE was my aim

My N2 boots from SD if inserted. CE stable is installed on EMMC.
There is nothing special to to if You want to boot from SD.

Another option is using petitboot
