Firmware reading and flashing Taranis X9D (original) with Companion 2.12.0-rc2 on Linux

[adelton]

Hello,

I've managed to build 2.12.0-rc2 on Fedora Linux, with rs_dfu statically linked.

When I try to read firmware from the Taranis (the radio is on 2.11.4, both bootloader and firmware), I get a message window

Radio could not be detected by DFU or UF2 modes.
Check cable is securely connected and radio lights are illuminated.
Note: USB mode is not suitable for reading firmware.

The USB cable is securely connected, because dmesg says

[354724.209218] usb 1-4: new full-speed USB device number 10 using xhci_hcd
[354724.333659] usb 1-4: New USB device found, idVendor=0483, idProduct=df11, bcdDevice=22.00
[354724.333674] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[354724.333679] usb 1-4: Product: STM32  BOOTLOADER
[354724.333683] usb 1-4: Manufacturer: STMicroelectronics
[354724.333687] usb 1-4: SerialNumber: 3368375D3332

and new /dev/bus/usb/001/010 defice appears.

Unlike with Companion 2.11.4 which included /usr/lib/udev/rules.d/45-edgetx-companion-taranis.rules which had MODE:="0666", the permissions on that device are now crw-rw-r--.

The message says "USB mode is not suitable for reading firmware". Fine, if the USB device is not used anymore, it does not matter that the write permissions are gone ... but what mode is suitable and how do I enable or configure it? In Companion? On the radio?

The message says "Check ... radio lights are illuminated". No, they are not. I've connected the radio turned off, like I did with any previous Companion and with dfu-utils. How do I make the lights illuminated with this new setup and how do I set up permissions for whatever device is supposed to be used with the dfu-utils-less approach?

In #6521 folks found the change fully working so I assume there is some upgrade step which I'm missing.

Thanks for any insights.
