Hi guys,

I need to modify device tree of Orin Nano 8GB Devkit for custom board in Jetpack 6.0 to enable SPI-CAN for MCP2515.

Currently i refer example for “mcp251xfd” to add in “spi@3210000” follow below address:

Linux_for_Tegra/source/kernel/kernel-jammy-src/Documentation/devicetree/bindings/net/can/microchip,mcp251xfd.yaml

However i also find out other overlay code in:

Linux_for_Tegra/source/hardware/nvidia/tegra/nv-public/overlay/jetson-can-mcp251x.dtsi

But i checked this overlay file is not included by any .dts file and not be complied into .dtbo

So what is the correct way to enable mcp5115?

Thanks a lot!

Hi thanhdq,

You can refer to Jetson/L4T/peripheral/ - eLinux.org to port MCP2515 module on Orin Nano devkit with JP6.0GA(R36.3.0), which has been verified from us.
