Orin Nano SPI not working

[KevinFFF]

I dropped the SPI frequency from 60Mhz to 40Mhz and now it works. On the Jetson Nano, I can drive with 60Mhz with no problem. I walked down by 10Mhz at a time to see what would work (after seeing signals on the scope).

Could you refer to the following thread to use different parent clock for SPI working with lower frequency?
