Hello @Abraham_Salazar @VladimirMbf

You must use this verison of Ubuntu image? VIM3_Ubuntu-gnome-focal_Linux-4.9_arm64_EMMC_V1.0.10-220108.img.xz

The issue is this image not compatible with the new hardware, if you must use it, then I will provide a repacked image to you.

@Abraham_Salazar, thank you so much for your image, I will try it

@numbqq yes please if you could make repack it would be great, because I think many people can search it because of this https://groups.google.com/g/doubango-ai/c/Q8C6cZnObtU
Really appreciate if you can see this @numbqq to understand a problem, why alpr maker using exactly V1.0.9 - 211217

Hello @VladimirMbf

I can’t find that image on my side, could you provide the orignal xz image VIM3_Ubuntu-gnome-focal_Linux-4.9_arm64_EMMC_V1.0.10-220108.img.xz to me?

The image from the above link seems encrypted?

right now, I successfully using target image from sd card - downloaded from right here - https://doubango.org/khadas_images/VIM3_Ubuntu-server-focal_Linux-4.9_arm64_SD-USB_V1.0.9-211217.img.xz

@numbqq can you please focus on this image version - VIM3_Ubuntu-server-focal_Linux-4.9_arm64_SD-USB_V1.0.9-211217.img
because it’s right target image for alpr solution

is it possible to get emmc image from
https://dl.khadas.com/products/vim3/firmware/ubuntu/generic/old/vim3_ubuntu-server-focal_linux-4.9_arm64_sd-usb_v1.0.9-211217-repack.img.xz ?

Because I have troubles to convert from already loaded linux 4.9 211217 from sd-usb as the source to emmc through emmc-install script (this solution not worked for me) - Write SD Image into eMMC [Khadas Docs]

also I tried latest (all two 4.9 server - fenix 1.4 and 1.5) images for emmc from here dl.khadas.com - Index of /products/vim3/firmware/ubuntu/emmc/
these images are not working with npu solution (gives an error)

it would be great to get repacked 4.9 211217 but for emmc (not for sd) image please

10

@numbqq yes please this is the compressed image img.xz

If you can repack for me, I would really appreciate it.

or if you can covert this sd image to emmc, also work for me too:

thanks

@Abraham_Salazar @VladimirMbf

For the SD image, you can use command sudo emmc-install to write the image to eMMC.

Anyway, I have also repacked the new eMMC image here.

12

@numbqq Thank you so much for your help!
I will try eMMC image today

13

15

Hi @numbqq is posible convert this image to SD version

Hello @Abraham_Salazar

You can try to use oowow to backup the image which can be write to the SD card.

Steps:

  • Flash image to eMMC
  • Use oowow to backup the image [1]
