OpenTX 2.2.1RC3 Improving your Tx
We are happy to bring you OpenTX 2.2.1RC3, with support for the production version of the FrSky Horus X10 / X10S and X7S radios!
PLEASE NOTE the following important information before hastily jumping on it: Please back up your models and settings before upgrading so that you can go back to your previous version should you not like 2.2.1RC3 or find issues that make it unsuitable for you. Use the “backup radio to file” companion feature for this to have an exact copy of what was on your radio.
The manual has not yet updated to include all Horus documentation/OpenTX 2.2 changes, so get yourself a good coffee to wake up, and refer to the great communities for help e.g. openrcforums here, RCGroups and threads like this one. You can pop in our chat room where other users and/or devs may be available.
Check during companion install that it installs itself in the correct directory, usually you want “Companion 2.2”. If you used 2.2 release candidates a bug may cause it to install itself in “Companion 2.1”, potentially overwriting your 2.1 install.
Companion supports reading and writing Horus firmware when the radio is powered off and then connected to USB, using dfu-util and the libusb drivers installed by Zadig, exactly like for the Taranis. See the “Flashing your Taranis Radio” section in this manual. Companion can back up existing firmware (see note below in known issues) including the stock FrSky one (save as .bin), and can flash the FrSky DFU bootloader so that no other tool and/or driver swapping is needed. You might need to disable the “Check hardware compatibility” checkbox in the flashing dialog.
SD card contents can be found here. Download the correct archive for your radio type, extract it to the root of an empty SD card and you’ll have all needed files. Please note that some existing OpenTX sound packs that where designed for 2.1 won’t work due to changes in the naming strategy, so you’ll likely want to use those that are included in this archive until popular 3rd-party packs are adapted.
OpenTX does not touch the internal flash of production Horus radios. Its contents do not need to be backed up and are not accessible in any way when OpenTX firmware is loaded.
There is no bootloader on Horus at this point. The SD card can be accessed while the radio is powered on and choosing the relevant option on USB pluging.
Due to changes introduces by Horus, image, sound, and script file names for ALL radio are restricted to 6 characters in most places.
By default, the setting for companion is to download release only firmware, you NEED to go to settings/settings/application settings and set it to “Use releases and release candidates (testing)” to get new radio firmware or simply 2.2.1RC3 firmware.
Companion now offers assistance for model conversion from one radio type to another. The transferred models NEED to be completely checked and validated before being used, as some things like switches assignments may not get converted properly. The proper way to transfer models from one radio to the other is: Select a profile for the destination radio, read the settings from the destination radio, open the source file or read the source radio, drag models onto the destination radio’s window, write destination radio.
The first versions of Frsky X10/X10s misuse the USB-C port for charging its internal battery. Do not plug anything else in there. For more details see here: FAQ for X10/X10s USB-C port
- If you get an “Invalid Language” error when trying to download firmware after upgrading from 2.1 open the profile settings and reselect your radio type, even if it is already correct.
- The progress bar in companion when reading firmware from a Horus is broken and will reach 100% at only 25% progress. Just wait, the window will close when the process is finished.
- Horus X12S production version and beta version use different hardware. Companion defaults to production hardware, for beta radios check the “pcbdev” firmware option in the profile settings.
Download and install Companion and use it to retrieve and transfer the latest OpenTX firmware to your radio after configuring the proper radio type.
MUST READ : Changes RESET function. There as been a major change between 2.2.0 and 2.2.1x on reset fonction. In the past, the reset function would be called only once. In 2.2.1x, the reset is executed periodicaly while the reset condition remains true. It does NOT means however that the target value will stay at 0 during that period, just that it will be periodicaly reset.
MUST READ : Binding Options is no longer a firmware choice, it is now part of baseline OpenTX. It means that when you are binding with a suitable module, a popup will appear when binding, asking you to make a choice on telemetry and channels available on receiver output pins (not SBUS). The effect of that choice depends on the receiver firmware type and version, please check receiver release notes and manuals for more details.
