Thanks Mike. Just to give some feedback. I tried, as you said, and was able to flash openTX from the SD card, but could not flash openTX bootloader. But that's ok, after a few minutes with openTX I went back to erskyTX. I prefer the menus layout in erskyTX.
Great job Mike

Thanks Mike. Will try flashing from SD Card. How do I know the OpenTX file size I'm trying to flash? Is it like checking a file/folder size on the PC with right click and selecting properties?

Thanks Mike. When I try to flash OpenTX using companion, the progress bar starts and shortly after a message pops up informing it was not possible to flash the firmware and mentions "unknown error". Is it possible to flash OpenTX from the SD Card using ErskyTX? There's no compatibility iss...

I have installed ErskyTX (and bootloader) in my sky9x v3 board. I'm running version r221 of ErskyTX, but I would like to try OpenTX. I already installed companion 2.2.3 and and downloaded the latest OpenTX firmware, but when I try to write it to the radio, a get an error and nothing happens. Can som...

What's the name of the wav file that plays in ErskyTX when the radio is shut down. Can't find it in the voice folder.

João

Thank João. Just that? No problems doing that having Ersky9x installed? And if I want to go back to Ersky9x just flash it with eepe?

I know, and it's a great firmware, but I would like to try openTX for the sky board, and if I don't like it I go back to Ersky9x, like I did in the stock board.

Sorry guys for the lack of feedback, but in the last few days I have been tinkering with the firmware in the radios and the flight controllers in the quads, trying to get back up to date. On question if someone can help me or point me in the right direction, although it may be off topic. As mentione...

An update. The 9x with the stock board seems to be ok according to you guys. This morning I grabbed the sky9x and managed, without any problems, to install the latest stable version (r221), and update the coprocessor to 107. Is this the most recent? However, there is something I would like to change...

So Mike, that's the latest stable version, but the number is wrong, correct?
That topic is the one I went to get the version (er9xProv822kI) mentioned in the last post.
Is that test version the latest one availiable?

Thanks guys. Reinhard, it seems that you were right. I verified the file in an editor and lines 1374 and 1375 were not the same as yours. So I downloaded the file again, and before flash I checked it, and now those lines show the same values as yours, so I tried to install it. All went fine, no erro...

Thank Reinhard.
But I downloaded the file several times, in different machines, and from different internet providers and the result is always the same error.

Yep. Right click in er9x standard and choose "save link as" . It saves the file as er9x.hex

Thanks João. The path is set correctly in the burn menu to AVRdude. Zadig was for the USB programmer since usbasp drivers are no longer available in the site, that now points to zadig. Besides, if the problem was the path how does it flashes one version and not the other? Enviado do meu Redmi Note 4...

Thanks João. Yep, the first time went fine. Had some problems with the drivers installed from zandig because eepe (avrdude) was not recognizing the USB programmer. But found some drivers for it, I think in some arduino page, and after that all went fine. I even made a backup of the eprom and the old...

It's completely dead João. After installing the required drivers and software I manage to flash er9x, but in the version page (can't remember what was it) it showed a date from 2016, so I went to er9x site and downloaded the latest standard version. I added the revision number to the file name (er9x...

Thank Mike.
I still have the same pc, but I will have to start from scratch since the machine has already been formated. I will give it a try during the weekend and give feedback.

Thanks Mike. I was referring to er9x for the stock board. For the sky9x board I will have to use a windows machine. Samba does not exist for Mac. I will give it a try during the weekend and will let you guys know how it goes. [emoji3] Just a little update. After some time installing drivers and soft...

Thanks.
If using a mac do I need both (eepe and eepskye) or eepe is enough for flashing the stock 9x

Guys, sorry to bring back this old topic, but I need some help, since I'm pretty much in the same boat as this user. As you can read from here (https://openrcforums.com/forum/viewtopic.php?f=2&t=11945&p=144762#p144762), I have been away from the hobby for several years, and I'm trying to com...

Thanks again João. And how do I install er9x standard firmware on the 9x. I have been reading my old posts and it seems that I used companion9x to install the firmware. For the sky board, you are right. The install was with samba. For the most up to date firmware do I need to use samba aswell? One m...

As for the one with the sky9x board, can't remember how I first installed the firmware. If I'm not mistaken I think that apart the firmware I also installed something else, eprom, maybe... As for the other 9x it has no mods. The only thing added was the lcd backlight and a ps2 connector for firmware...

Thanks João. I just opened the rádios and the stock 9x has an atmega 64A. The modded one, tried as you suggested, holding the horizontal trims toward the center when powering the radio, and nothing happens. It boots normally to the installed firmware. Don't know if it helps, but it's a sky9x arm 3.0...

Thanks for the help João. Hummm, let me guess... :) I have been in that page, but, as a I said, I've been away for so long that I dont know what firmware is appropriate for each of the boards :shock: . I guess that ER9X (revision 821) is for the turnigy 9x (and similares) with stock board, but how d...

Hello guys. First I would like to apologize if is this is not the right place for the post, but didn't know where to open it. I'm an rc enthusiast for some time, but in 2014 or 2015 I took a break in the hobby for several reasons. Now I would like to come back but after 4 or 5 years a lot has change...

2.

sorry guys for taking so long to reply. I dont know what to say but today I was going to test everything again to post here the results you asked for, and all went fine. Did everything as the last time, but today I was able to flash the latest version of open TX and upload the eeppe file without a p...

Yes, all this is using latest version of companion. Dont know if i'm making my self clear, sorry. It's like this. -if i flash the tx with the latest version using companion i get a blank screen, and it will not boot or get into usb mode -have to use erase jumper and flash the tx using samba -with sa...
