Hello,

I have a problem with my radio Turnigy 9x. I flashed it on OpenTx firmware and since then the radio is behaving strangely.
More on the video: https://www.youtube.com/watch?v=HFqtms8ndgA and https://youtu.be/HXsGQ1VaM2M

I used the the latest Companion software with the argument -B 100.
Before that on Turnigy firmware buttons acted normally. Sometimes the radio operates normally (about 1 minute - with OpenTx), and then starts to do weird things like on video.

Any ideas?

Sorry to use Google Trasnlate.

What does it say on the screen when it turns ON?

Did you use companion to download the firmware? What are your configurations? Is the processor setting correct in companion?
Why did you use -B 100? did you have problems to flash the radio before?
Another question, did you use the -F option in the extra argumnts?
I would say the fuses could be messed up. Please read the fuses using companion and post them here.

I had problems with the flashing. Sometimes expected different ID. That is why I use -B 100.
Firmware is downloaded only via Companion.
Radio is V2 version with AT Mega128.
Here is the settings:


I do not use -F argument.

Now I desoldered connector for flashing and everything working properly. :-/ It's probably a problem in soldering.

Are you sure you have an Atmega128 in your turnigy 9x? they normally come with the atmega64

If you didn't change the chip, it will have an Atmega64 not an Atmega128..

here is pic

This is the new board, version 15, as it is sold from HK as spare

Hmm, that is new, since when is the 9x radio sold with an atmega128.. We know that the replacement boards are sold with the 128, but it is the first radio i see with that chip..

Is the radio now working ok after desoldering the wires?
Did you leave the programmer attached to the radio before? some programmers can't be left connected to the radio..

Yeah radio now working. I ordered this radio last month and come with this board.

It's great that it works now.
And also it is great that the 9x now comes with the Atmega128A chip. Shame they didn't go for the Atmega2561 instead. But better than nothing
