It is possible to upgrade one OS in DualOS eMMC install?

Hi, I have installed Nougat/Ubuntu DualOS V171028 on my VIM Pro and I’d like to replace Nougat by ATV without touching the Ubuntu. It is possible?

I think it’s possible:

  • Boot into Ubuntu
  • Unpack the ATV ROM with images
  • Use dd command to replace to new images, i.e.:
root@Khadas:~# dd if=path-to-image-boot.img of=path-to-partition-bootimg

You might take a high risk to try that.

Enjoy!

Ok, thanks for the response.

The problem is, that there are no device nodes for the emmc partitions available in the Ubuntu. I can only see the whole emmc device, boot0 boot1 and rpmb. I’m going to try the same operation in uboot, though.

Shouldn’t be.

Can you run following commands and paste the result:

ls /dev

Thanks!
