去接收外设发过来的信号，我需要配置什么东西吗

Hi 2668729889,

Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?

Are you using SPI0 or SPI1?

If you want to use SPI as Slave, please refer to the following thread to configure in device tree.
SPI0 interface configured as a slave in Jetson Xavier NX - #10 by borjabasket14

devkit for orin nano, R35 (release), REVISION: 4.1,jetpack 5.1.2-b104
using SPI1

I looked at kernel printing

I modified the device tree and jetson-io.py based on the final conclusion in the post
i just made modifications

What could possibly have caused these errors

Please share the full dmesg after you modify the device tree.

It is still using SPI master driver.

The method I loaded is
sudo insmod spi-tegra124-slave.ko
sudo modprobe spidev
I can’t have/dev/spidev2.0 devices without loading spidev

I don’t know where this spi_master print came from either

It should be loaded automatically by default.

There’re 2 SPI interface available by defualt.
It seems you’ve configured 3230000.spi as slave.
Please share the full dmesg for further check.
