M1 wont boot some images listed in netboot

[aa7jc]

I just received my M1 and have had strange issues when trying to install certain images listed in the net boot options.

What happens when I select the first item "ubuntu 22.04 (Jammy Jellyfish)" the screen goes black and then my HDMI display displays "INVALID FORMAT"
I have waited over 30 minutes and the error never clears

I am able to install the second item which ubuntu 20.04 (focal fassa)and it works OK
The Debian 11 (bullseye) does the same "INVALID FORMAT" thing.

So.. Is this normal? If not, what am I doing wrong?

My procedure is:

exit
udhcpc
netboot_default
exit
select OS image to install

installation media was 120 GB SSD drive and 64 GGB SD card, both gave same result.
I have an M.2 drive installed but I have not tried to install to it yet.

Board is brand new and no changes to any boot params

In case the display works with Ubuntu 20.04 and Debian 10, while Ubuntu 22.04 and Debian 11 does not, I believe it's the kernel driver issue for the unsupported display. Ubuntu 20.04 and Debian 10 comes with Hardkernel's stock kernel version 4.19 which is based on Rockchip BSP, Ubuntu 22.04 and Debian 11 comes with upstream kernel 5.18+ so the driver would not work with a certain hardware.

Please share the detail of your display to check if it's supported by the kernel.

The display is a very cheap LG television with HDMI inputs ...So yes I am very grateful for your knowledge and insight.

You are exactly right that the Debian 10 and Ubuntu 20.04 are the only images that boot from the netboot menu using my HDMI TV monitor

OK! Very good.. So now I have an excuse to buy a new computer monitor.. Lol!

FWIW, here is a photo of the display I am having the issues with but I am certain you are right about it. Thanks again!

Nice chance!! Congratulation!!

I've checked your monitor and the problem is because of the resolution 1366x768, the driver has its resolution but it may not compatible with your display for some reason. Need to check why...

Hi,
I'm having the same problem and I tried on recent monitors:

Samsung LU28E570DS/EN

Samsung UE43NU7400

It works only for Ubuntu Mantic, It doesn't work for Ubuntu Focal and Jammy. It's really annoying and makes very hard to install a new OS.

Please, let me know if an alternative solution exists (recompiling the Kernel with different configurations)

Thank you.

Please clarify what's the exact problem you have.
Isn't the netboot installer started or Ubuntu Focal/Jammy does not start after installation?
When the problem happens, what's the status of blue LED or what logs do you have?

Hi,
I start the board and run the netboot_default command in the console.
After executing the command I see the list of available OSes in the Petitboot menu

If I select Focal or Jammy, the board download the files and I see the message "perform kexec". After this step, the screen remains black and I don't see anything.
The blue led is blinking.

If I select Ubuntu Mantic Minotaur I'm able to see the installation menu.

You already posted same issue and got answered by me to try with other display, but you do not have. It's incompatible Linux kernel issue, as of now you would better to flash the OS image instead of installing via netboot installer if you cannot try with other display.

I tested with the second monitor I mentioned in my previous work (thought that it could work) but not luck.

Ok, I'll flash the image on the disk.
Thanks,

Hi Tobetter,
I tested using the method C mentioned in this post: viewtopic.php?t=44477

I downloaded the image from here: http://ppa.linuxfactory.or.kr/images/ra ... 531.img.xz
then unxz and copied on a SD card (without using dd, just cp)
The sd card is automatically mounted when Petitboot starts.
After dding the image on the ssd disk I powered off the OdroidM1.
After the reboot, Petitboot notices an Ubuntu 22.04 LTS installation on /dev/sda1

then "Performing kexec load" and black screen (invalid format on one monitor)

I think this is not related to the monitor... my monitors are new and I never had similar issues with other boards.
Fun fact: after getting the "invalid format" error on one monitor, I unplugged the hdmi cable (without powering off the board) and attached the same cable to another monitor. I was able to see the ubuntu login console. I was also able to login (odroid/odroid) but the network is disabled and it's a bit hard to reconfigure because the resolution is wrong and the text is yellow.

Please, let me know how to debug this problem.

Regards,
Marco

EDIT:
after running "sudo dhclient" I'm able to ssh to the machine and everything is working but I still need to understand how to fix this.

Hi,
after running "apt upgrade" and installing the kernel 6.1.0-odroid-arm64 I confirm that the screen is visible.

Is it possible to have a new entry in the netboot_default list with Jammy and Kernel 6.1.0?
