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/”
  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?


How do check the SPI configure lost???

run again, the ‘spi’ is unselected.

and the orin spi clock isn’t wave…
