Hi,

I checked the post, should be related to gpio based cs, but in our case, we are using spi1_cs0(pin24), should be hardware based cs.

after I upgrade my jetson to R23.7.4, and back to 4.6.1, both software spi is not working, even with the loopback mode for the spi, I don’t know why, seems I have some issue with the spi on my device.

I would suggest verifying SPI loopback test with latest R32.7.4 (JP4.6.4) first.
Please refer the the following thread for this.
