Jetpack 4.6 jetson-io.py does not work

After following instructions here Getting Started With Jetson Xavier NX Developer Kit | NVIDIA Developer and performing a software update, I am trying to run jetson-io.py for the first time.

I’ve read the other forum threads and my issue appears to be slightly different. jetson-io.py itself just flashes the terminal and exits. This is the output I get underneath that:

sudo /opt/nvidia/jetson-io/config-by-pin.py 
Traceback (most recent call last):
  File "/opt/nvidia/jetson-io/config-by-pin.py", line 84, in <module>
    main()
  File "/opt/nvidia/jetson-io/config-by-pin.py", line 39, in main
    jetson = board.Board()
  File "/opt/nvidia/jetson-io/Jetson/board.py", line 231, in __init__
    self.bootdir)
  File "/opt/nvidia/jetson-io/Utils/dtc.py", line 120, in find_compatible_dtbo_files
    c = get_compatible(dtbo).split()
AttributeError: 'NoneType' object has no attribute 'split'

I have:

cat /sys/firmware/devicetree/base/compatible
nvidia,p3449-0000+p3668-0000nvidia,p3449-0000+p3668-0001nvidia,p3509-0000+p3668-0000nvidia,p3509-0000+p3668-0001nvidia,tegra194

fdtget /boot/dtb/*.dtb / compatible
nvidia,p3449-0000+p3668-0000 nvidia,p3449-0000+p3668-0001 nvidia,p3509-0000+p3668-0000 nvidia,p3509-0000+p3668-0001 nvidia,tegra194

What is the problem?

I found a fix for this problem.

See Jetson-io dtc.py bug

Glad to know issue fixed.
