Pixhawk 6x Rev8 Bugs #23514
Comments
@dagar please check this bugs |
I've used a few Pixhawk 6x Rev 8 running 1.14.3 but with the cm4 baseboard and not had any of these issues, Although not using an identical setup. Have a few ideas:
I haven't used that baseboard so its possible the issue could be with that. |
Thank you very much. |
Describe the bug
We purchased three Pixhawk 6x Rev 8 with Standard Baseboard V1. The first autopilot already had the PX4 v1.14.2 dev firmware and the second autopilot already had the PX4 v1.15.0 alpha firmware, both of which versions are not stable. TELEM1 port of the autopilots does not work, by changing the MAV_0_CONFIG parameter to TELEM2 and connecting of the telemetry module to TELEM2 port, there is not communication between autopilot and QGroundControl. But by changing the MAV_0_CONFIG parameter to TELEM3 and connecting the telemetry module to TELEM3 port, there is communication.
The value of the Bat1_V_DIV parameter (Battery 1 Voltage divider) cannot be changed from -1 by pressing the Calculate button. By reading its description in the PX4 site, I did not understand how much I should set for it. Also, by resetting the parameter values of the PX4 v1.15.0 alpha firmware to their default values, the corresponding autopilot will have many problems. Fortunately, it will return to its previous state after loading the parameter values of the PX4 v1.14.2 dev firmware to it.
We updated the third autopilot firmware to PX4 v1.14.3 Stable version using QGroundControl. Unfortunately, there are the following problems:
1- TELEM1 port does not work, unlike the other two firmwares, changing the MAV_0_CONFIG parameter to TELEM2 and TELEM3 and connecting the telemetry module to TELEM2 and TELEM3 ports, problem remains.
2- The value of the Bat1_V_DIV parameter (Battery 1 Voltage divider) cannot be changed from -1 by pressing the Calculate button. By reading its description in the PX4 site, I did not understand how much I should set for it.
3- The radio control does not work, we tried with two radios from FrSky and RadioLink, but the message “Please turn on transmitter” is always displayed after trying to calibrate the radio controller. After hours of checking the difference of the parameters of the available firmwares, it seems that the problem is with the RC_INPUT_PROTO parameter and the code related to it, because when we select all of its options and restart all the components, the problem remains. This parameter does not exist in the dev and alpha firmwares
4- None of the motors rotate, because the necessary signal is not sent to the speed controllers.
5- Ardupilot firmware cannot be installed on the autopilots.
To Reproduce
by using QGC Update the firmware of Pixhawk 6x Rev8 to PX4 v1.14.3 Stable version
Expected behavior
TELEM1 port can be used. Bat1_V_DIV parameter (Battery 1 Voltage divider) can be changed from -1 by pressing the Calculate button. RC can be calibrated. Motors can rotate. Ardupilot firmware can be installed on the autopilots.

Matching bound rules
Additional context
On Holybro's website, it is mentioned that this new autopilot (Pixhawk 6x Rev 8) is compatible with PX4 v1.14.3 stable firmware, but a non-stable version was already loaded on them. Currently, the latest stable firmware of the PX4 autopilot is version v1.14.3, and the previous stable version that can be downloaded on GitHub is v1.13.3, unfortunately both of which are not compatible with these autopilots. There are not even alpha and dev firmwares on GitHub or other sites that we can load them on the third autopilot and work with temporarily until these problems are solved in the next stable version.
Please send the download link of PX4 v1.14.2 dev and PX4 v1.15.0 alpha firmwares through this email. Also advise us how to minimize the possibility of the crash using these unstable firmware and very new hardware. In the end, I hope the necessary feedback would be sent to the PX4 and Ardupilot firmware teams so that they can provide stable firmwares compatible with this hardware as soon as possible.
Thanks
