FS-TH9X doesn'tturn on after ER9x flash

[eranka]

Hi, my FS-TH9X doesn't turn on after ER9x flash. I had the new ER9x firmware installed and it was fine but I wanted to add S-FHSS protocol (I wasn't sure if I already had the installed) so I found something from an old thread on the forum and flashed it and now it won't power on

few important things:
1. It powers on with the AVR USB still connected but not with the battery
2. I flashed it with the switch ON by mistake (hope it didn't harm the firmware)
3. I tried using "Set fuses to protect EEPROM" but it didn't solve it
4. I re-installed the last ER9X version and it didn't solve it also

I really hope someone knows how to fix it and can share his experience

Thanks,
Eran

What processor do you have (64/128/2561)?
What file (exactly) did you flash?

I think it's a 64 but I can't know for sure until you tell me how to check it. Once, I was foolish enough to try and flash the er9x-128.hex and it crushed leaving me with a turned-off screen. I fixed it by flashing the latest er9x.hex file.
This time I flashed the er9x.hex which I extracted from this folder: er9xProv822k

You would then need to open up the case and read the top of the chip.
Sounds like you may have a 64 then.

Go here for your download: (http://www.er9x.com/).
May be one of these unless you have other mods done:
er9x standard (right click and select 'save as')
or
er9x for M64-FrSky (right click and select 'save as')

The standard version is the one I originally flashed and it worked fine but now after my bad flashing experience it doesn't repair the on/off switch problem, I can only turn the transmitter on by connecting the AVR USB

I can only turn the transmitter on by connecting the AVR USB

And that means the processor is working, but you have another hardware problem there. probably a blown trace somewhere, a blown voltage regulator, or both. Please open the radio, and take a good resolution picture of the mainboard. Post it here.

Also, ever power the radio from the programmer and the battery at the same time.

Hi João,

As it turned out, the actions I did yesterday night (flashing the standard mod and "Set fuses to protect EEPROM" did solve the problem, I guess I was too tired to notice it
Anyway, the main purpose which had led to this problem was my trial to add the S-FHSS protocol, can you tell me how to do it the right way?
I added a picture of my main chip if it helps

Thanks!!!

So, all is working again then?

I am not sure that protocol is supported by er9x? At least I don't seem to have it on my Er9x radio, but perhaps my radio doesn't have the latest version installed..

João

[eranka]

Actually I fixed it using some data I read on some old threads of you and Mike you guys are great.
It's too bad that the er9x doesn't support it, I wanted to buy a BNF micro heli for some practicing on my lawn but now I have to buy it including it's TX which makes it expensive

[jhsa]

Wait to see what Mike says.. I don't really know if it is supported but I think Mike said once that he still couldn't implement it because he doesn't have any TX or receiver using that protocol

João

[eranka]

Ahh OK, let's wait for Mike respond

[Kilrah]

I think he's talking of using a multiprotocol module to talk S-FHSS, but the only way to be sure is for him to actually give enough detail.

[eranka]

The XK K110 helicopter I wanted to purchase Uses 2.4GHZ FUTABA S-FHSS communication agreement (I copied and pasted the description, hope you understand it better than I do)

[Kilrah]

Yes, and how were you expecting to control it? You need a transmitter module that can talk S-FHSS in your radio for that.

[eranka]

I guess that's showing my level of understanding
Good thing is, I still have the time and capacity to learn new stuff

[jhsa]

AHHHHH, I think you need the multiprotocol module, as Kilrah suggested.. I didn't recognize the protocol, I thought you wanted to use the original RF module that comes with the radio..
Do you already buy the multiprotocol module?

João

[eranka]

I'm just hearing about this module for the first time, I was recently back to the hobby after few years of break I guess it was born somewhere in this time. Can you share a link or a picture of this module?

[eranka]

Thanks Kilrah, this module will allow me to operate the XK K110 helicopter with my transmitter?

Great, thanks João
