rkflashkit non-functional

stentmartin

I have the same problem and I have used the recommendations here to install Linux upgrade_tool 1.2.
Everything looks right but my Ubuntu host downt recognize the RK3399 device. I have a message
“ List of rockusb connected”  no found rockusb........ and I quit.

I have downloaded Ubuntu 1604 2017 0511 1112.img from firefly website.
I have renamed and installed everything according to the information here.

I have Ubuntu 16.10 64 bit on my host.

I have tried both recommended methods with the C-connection and Recovery and Reset keys.
Nothing I do makes the my Ubuntu Host to recognize the device!?

Please advise

I found a third method to set the device in “Loader Mode”. The method what’s totally different from the other instructions on Internet. However this time it worked and I can start the upgrade_tool and chose my device.

However when I try to low format and flash the device I get an error: “creating comm object failed”!

It seems as the memory in the device can not be formatted or flashed for some reason. Maybe the memory is protected?
There is also many different Ubuntu.img on the website. Which one is the correct to use?

The messages I have is as follows when I do “upgrade_tool uf update.img”.
1. Loading firmware
2. Support type: RK330C?? FW Ver: 6.0.01
3. Loader Version: 1.05
4. Creating comm object failed

When I try to do low format “upgrade_tool lf”, I have the following messages:
1. Lower format quit, Creating comm object failed.

Anyone else with this problem!
