Hi Folks

It have a tx issue that I can't resolve. I tried updating my Taranis X9D+ so it could be compatible with the latest receivers and somehow have corrupted the bootloader such that I can't enter the bootloader as when I enter the bootloader by the trims inwards/ power on method the TX goes white screen with constant vibration/buzzing, and I cannot see the Tx via USB on either laptop/PC or via the Companion app.

I had V 2.16 and was hoping to update to X9DP V2.2.2-20180525 and update the bootloader accordingly.

If anyone has a cure for this that can be passed on it would be appreciated.

Cheers.

From memory, Ady, you can write the firmware to the TX by connecting the USB cable while the TX is switched off.

With Tx still switched off you just write the firmware to Tx using companion.

Remember that you MUST have selected the correct model of Taranis, in companion settings, BEFORE downloading the firmware from the net. That's the only way to get the right version for your Tx.

I seem to remember that the hardest bit is getting the USB drivers to work so the PC sees the Tx.

Ask here if you're having trouble at that point.

Hi Chris,

Many thanks for your reply. Unfortunately the USB is not recognised by my Win10 PC or Win10 Laptop. I have tried the Zadig utility and other recommended USB drivers to no avail. I can write to the Micro SD card if connected directly to the computers.but that is the extent of my USB connectivity.

Hi Ady, sorry just saw this again.

The other thing to suggest, then, is that there have been many reports of FrsKy USB ports being very fussy about USB voltages. So much so that trying every USB socket on the PC may help, and/or having to try two or three different cables.

I had troubles with USB connections, you only had to move them a fraction and the connection would go. Pounland do some good USB cables belive it or not yes

I had read the same on the Open TX forums and tried every port on both machines on 3 different cables. I found one cable was dodgy but the others were faultless with other devices but no joy with the Taranis crying 2

I get the windows sound to indicate the USB is connected but nothing is seen on the PC. In the Devices window it indicates the drivers are loaded but doesn't show the TX or drives. Been trying to resolve this since last Tuesday and its driving me crazy. face 24

Yes Trebor. A good find. I've used some of the micro USB cables from Poundland and not had any issues with them.

Sounds very frustrating, you're very close.

If I get a minute tomorrow I'll plug my Tarsnis into the PC, run zadig and check exactly which driver is installed that works and just what drives, if any, I see.

I'll report back.
Unless anyone else can post better info in the meantime.

Two questions:

1. You can't access the bootloader, but does the radio start normally?

2. When you plug in the USB with the power off, do you see a device in the "Devices and Printers" caled "STM Bootloader"?

Have you picked up a charging only USB cable ? What about after version 2.2 you don't have to hold the trim switches in like before or have I got my knickers in a twist.

Ps, have you updated it yet or trying to ?

??? OpenTx has little or nothing to do with receiver compatibility - that's all down to the firmware for the RF module, which is an entirely different thing!

From memory (and its quite a while since I did it!), you *can* upgrade the RF firmware using recent versions of OpenTx, but your original post implies that you were under a false impression. Or am I reading it incorrectly?

If its any consolation, I've just had a similar experience upgrading my new X10S from FrSky to OpenTx. Although I managed it OK eventually, I had to adopt a method contradictory to that shown in the "bible" and all the YouTube videos.

iirc I had problems configuring Zadig, possibly because I tried todo it without the Taranis connected so no STM32 was found.  I think that once I realised that I needed the tx plugged in to run Zadig it worked ok.

Many thanks for the link James. It's looking useful. The whole episode started when I found that my Taranis would not bind to the receivers produced recently so the intention was to update the radio to the 2.2.2 version and then update my older receivers to the later firmwares but stumbled at the first hurdle.

As I hinted in my earlier post, simply switching to a more recent OpenTx won't help, though it may make life a bit easier.

You will also need to update the firmware in the transmitter RF module, as well as your older receivers.

But get OpenTx sorted first, then come back and ask about the rest!

There's a guide here: http://dronehitech.com/en/frsky-taranis-firmware-update/

but it only works with recent versions of OpenTx.

Yay! James's link did the trick and the Tx is no longer locked when I press trims together and switch on. I'm very relieved and grateful for the help.

Cheers All
