CSI Camera Thermal and RGB

Is it custom setup or the whole is done by a vendor ?
For the latter case I cannot say without more info, but for a custom setup, I’d expect a USB link for Boson.
Do you have an USB cable for connecting Boson to Jetson ? If yes, you may check for kernel error messages with dmesg. You may put the logs into a kern.log file and attach it to your next post:

sudo dmesg > kern.log

[EDIT: Also seen this post, but it is several years old, someone better skilled would better tell.]

[EDIT2: Just a thought, not sure at all, but if you’ve installed gstreamer you may try to display one of the last modes listed (1288x738). There is a bug in v4l2-ctl where it fails to display correct framerate if multiple ones are available for same resolution in same format. But 60 fps should be ok, so you would try :

gst-launch-1.0 -v nvarguscamerasrc ! 'video/x-raw(memory:NVMM),format=NV12,width=1288,height=738,framerate=60/1' ! autovideosink
