Hi,

I had some issues with my pico kvm and followed the instructions on the "Offline Firmware Update" page on the wiki to factory flash it. I tried both Luckfox-PicoKVM-Lite-Image-MicroSD.img and Luckfox-PicoKVM-Sys0.1.6-App0.1.2.img.

Nothing listening on port 80 or 443:

It appears that I am facing some kind of copy protection.

Could you assist with recovery?

Thanks

Hi, i have the same problem. I accidentally formatted one of the eMMC partitions (but not he security partition) instead of the SD card.

I tried the factory image and the other image Luckfox-PicoKVM-Sys0.1.6-App0.1.2.img available on Google Drive.

SSH is working but no webserver.

Code: Select all

/userdata/picokvm/bin/kvm_app

Claude found that the "https://github.com/LuckfoxTECH/luckfox- ... ptee_v2/ta" file is missing. I copied it over but it didn't change anything. Its the wrong one.

I managed to fix the problem by copying the right .ta file onto the device:

Code: Select all

scp user@server:/Downloads/fox/6121a5c4-345d-4883-9762-412ecbdbf8a3.ta .
cp 6121a5c4-345d-4883-9762-412ecbdbf8a3.ta /lib/optee_armtz/.
reboot

afterwards the webserver starts and you can perform an OTA Uprade again.

the file can be found here:
https://filebin.net/31azny8839yhxijg/61 ... bdbf8a3.ta

I hope this will be fixed.
