I try to add MCP 2515 to my Jetson nano (JetPack 4.6.1)

sudo /opt/nvidia/jetson-io/jetson-io.py

And I totally sure that the MCP 2515 correctly connect with Jetson nano, but the can module cannot be recognized, and I get

[    5.299378] mcp251x spi0.0: MCP251x didn't enter in conf mode after reset
[    5.307244] mcp251x spi0.0: Probe failed, err=16
[    5.319382] mcp251x: probe of spi0.0 failed with error -16
[    6.364226] mcp251x spi1.0: MCP251x didn't enter in conf mode after reset

[    6.380152] mcp251x: probe of spi1.0 failed with error -16

And I cannot solve this problem, it’s blocked 2 weeks.

Hi 1030789164,

Are you using the devkit or custom board for Jetson Nano?

Have you enabled SPI and verify SPI loopback test before porting and enabling MCP2515?
