Problem flashing Debian or Ubuntu from oowow to emmc

Which system do you use? Android, Ubuntu, OOWOW or others?

OOWOW

I tried to install an official distro of linux today on my edge 2 and it’s not working OOWOW tell me that the image is undefined not recognized etc… and if I install it anyway it doesn’t boot on it. What am I doing wrong here? Simple thing should work but maybe am I missing something, anyone ?

My process:
download on khadas download page the image
edge2-ubuntu-22.04-gnome-linux-5.10-fenix-1.2-221018-emmc
or
edge2-debian-241216-test
put it on a usb drive
connect the usb drive to the khadas boot OOWOW start choose option 2 flash emmc find the image on the usb drive and install
Result:
Not booting on the image

I could use the wizard who seems to be the best alternative but it require an internet connection wich I can’t setup for now and I don’t want to be internet dependent to flash image on the Edge 2 …

suitable image dl.khadas.com - Index of /products/oowow/images/edge2/

  1. prepare USB flash - suitable format FAT / exFAT / EXT4 - or going to OOWOW 1st and format via oowow
  2. put some images from dl.khadas.com - Index of /products/oowow/images/edge2/ into flash
  3. boot into OOWOW and plug usb FLASH with images
  4. select aviable image from USB flash to eMMC write

Wellcome
