How to active ‘spi’ on orin agx dev kit?

i configured the 40-pins according to this link.:‘Welcome — Jetson Linux<br/>Developer Guide 34.1 documentation

  1. Run “sudo /opt/nvidia/jetson-io/jetson-io.py”
  2. Configure Jetson 40pin header
  3. select spi1 , save and reboot

But the spi’s config lost after reboot.

What do you mean SPI’s config lost?

yes.

How do check the SPI configure lost???

run jetson-io.py again, the ‘spi’ is unselected.

and the orin spi clock isn’t wave…
