OK - this is probably my fault but I hopefully someone here will take pity on me. I have an new TBS Disco Pro, and the gimbal initailly worked during brief testing while in construction. Somewhere along the line in construction I upgraded the firmware to 2.2 or later (which I now read is inadvisable on the disco and its best sticking with 2.1). Gimball now just twitching uncontrollably on powerup. I get GUI mismatch - despite having downloaded ALL the versions of the GUI and tried each in turn. I have tried to reload 2.1 firmware in each of the GUIs - all fail with AVRDUDE exit code error. I have tried X-loader which failed I have tried AVRDUDE app - similar result.
SO - can any kind soul help me out with this? How do you tackle this? Wipe the board? Or is there something I'm missing?
Just download and install the latest GUI and firmware for your version, 8-bit or 32-bit.
Then start the GUI, everything powered and connected, and upgrade firmware.
At the beginning it could shake and move weirdly, just set PIDs and power to 0 and start configuration, and finally stabilization settings (PID/power).
