@teyrana I tried testing this (after rebasing on px4 current master) and still getting "Detected 0 radio channels." My steps in full: ``` git checkout pr-srxl2 git rebase master #this...

@teyrana confirmed that `rc_input start` and `rc_input status` give good results ``` INFO [rc_input] Max update rate: 250 Hz INFO [rc_input] UART device: /dev/ttyS4 INFO [rc_input] UART RX bytes: 325405...

Also (partially) confirmed that when connected to servos, radio transmitter commands are actuated by servos. I say partially because there are two concerns: - There are sometimes delays between the...

Update on the two issues from my physical test: (1) I am now getting elevator and motor responses to my commands. I'm not sure why elevator wasn't working before, but...

@teyrana I got some data but haven't been able to sift through it all. Once I'm back from traveling I'll upload it here.

[log_119.zip](https://github.com/PX4/PX4-Autopilot/files/7883827/log_119.zip) This file has a couple instances where the servos "lock up" like the previous video has shown. I'll try and get another set of data to upload. In order...

Here's another data log that shows the same behavior. I believe that the SRXL2 protocol is not processing RC commands correctly, because the topic `input_rc` that `RCInput.cpp` publishes to is...

@teyrana Put the files from the attached etc.zip file on the Pixhawk's SD card (see https://docs.px4.io/v1.12/en/concept/system_startup.html and https://docs.px4.io/v1.12/en/concept/sd_card_layout.html for more details). `extras.txt` specifies that both `rc_input` and `logger` should run...

@teyrana Testing update here. I believe I've been able to rule out the remaining PX4 or Pixhawk hardware as causing the intermittent freezes. I replaced the SPM4651T (which uses the...

@booo Ditto on the request. The instructions for building QGroundControl require building Qt5. I've tried numerous times on Nvidia Jetson to build qt5, but the build fails, and I'm not...
