Jetson-io.py Error on Jetson Orin

Hello, I’m new to Jetson machines, and I would like to use pin40 header (for custom SPI devices).
I ran /opt/nvidia/jetson-io/jetson-io.py, and got this error message:

Traceback (most recent call last):
  File "/opt/nvidia/jetson-io/jetson-io.py", line 25, in <module>
    from Jetson import board
  File "/opt/nvidia/jetson-io/Jetson/board.py", line 28, in <module>
    import Headers
  File "/opt/nvidia/jetson-io/Headers/__init__.py", line 34, in <module>
    if hdr.HDR.default:
AttributeError: module 'Headers.__init++' has no attribute 'HDR'

I searched “jetson-io for orin”, and according to this post, Orin doesn’t support jetson-io.py. Also, it seems like some dtb files are missing, so I need to get them from kernel source codes.

Are there any updates I could download to get jetson-io working? I think jetson-io is a really helpful tool, especially for people like me who don’t have much experience in embedded system.

Just to confirm, to get things working, I need to download kernel source codes (Board Support Package), build the kernel image, build kernel modules, copy the kernel image to the /boot directory, and finally reboot. Is this procedure correct?

I’m pretty new to this area, any help or advice is highly appreciated!

Hey, I ran into the same issue. The only way I could make any of the I/O work as expected is by creating a config with the pinmux excel sheet and reflashing. You can use devmem in Busybox, but it doesn’t seem to work in all cases

Will be available for next release. (J5.0EA)
