Hi Eric,

which Probles do you encounter?

Do you have mikrobus-capes or another cape/shield?

i can send you my working dts for Angstrom if you want to.

A good starting point for getting this stuff working (if you’re not using a mikrobus/cape) is to check TowerTechs TT3201 dts files, that’s where i started. Maybe you can post your dts files and i’ll see what i can make.

For me it is definitly working.
so far,
Ferdinand

Hi,

I’m currently trying to get MCP2515 working via SPI0.0. I’ve written my device tree overlay and loaded it with BB-SPIDEV0, but it isn’t working (error from dmesg below). Please could you share/send your working DTS file?

mcp251x spi0.0: could not find pctldev for node /ocp/interrupt-controller@48200000, deferring probe

Thanks,
Mark
