Sometimes things go wrong, and you need a way to recover your system, either by restoring a backup or accessing your system to check it out and hopefully fix the issue.
Krescue is a minimal firmware image (21MB compressed) for Khadas VIM boards designed to do just that, and more.
Some of the highlights of Krescue firmware image include:
- Full eMMC flash dump/backup to Micro SD card, USB, or LAN host.
- Restore the compressed dump (.img.gz) into an eMMC on the same device or another device
- Rescue shell for expert users.
- Shell access via UART, USB network, and Web browser
You’ll find Krescue for Khadas VIM1, VIM2, VIM3 and VIM3L on Khadas website which can be flashed to a MicroSD card using balenaEtcher. You can then insert the card into your board, and boot into maskROM mode to access the menu above, and control it with the IR remote control or USB keyboard.
You can see the minimal OS in action in the video below.

For having tried it quickly on my VIM3L a month ago or so, I found that it was a very well though tool that’s really made for people who want to recover access to their lost board. You’re not bothered with stupid interfaces nor logins and prompts that you never know, all possible information is accessible immediately from the CLI, SSH or web interface to help you figure how to proceed. I see it mostly for non-beginners though, but it was a hundred time more pleasant to use than tools made for beginners that try to hide the important information! It’s really great that at least one vendor devotes some time to improve their customers’ experience in this area.
Sometimes it turns out, that the best tools are the ones, that were built by developers for themselves internally. Krescue surely feels like one.
YES! i think same !!!
