Device Tree • Re: MCP251XFD fails to load dynamically

I reconfigured SPI0 with 4 chipselects and all 4 loads fine using config.txt

sudo dtoverlay mcp251xfd spi3-0 interrupt=4

Code:

[ 1640.864718] mcp251xfd spi0.3 (unnamed net_device) (uninitialized): Failed to read Oscillator Configuration Register (osc=0x00000000).

1. The mcp251xfd overlay doesn't have an spi3-0 parameter - see "dtoverlay -h mcp251xfd".
2. If what you meant was spi0-3, which would match up with your first statement, then the overlay doesn't have that parameter either, although it wouldn't be difficult to add one.

Show all the dtparam and dtoverlay settings you have in config.txt.
