Hi,

 

I've been trying to enable SPI on my Odroid-C2 running Armbian Buster but I can't figure it out, I tried with overlays, modprobe-ing the modules, nothing works.

I've uploaded my logs.

We didn't developed overlays for SPI yet, so you can't enable this feature fancy way, but we manage to add SPI support which I believe it works, but it is, as expected, disabled by default. Editing a device tree by hand and/or creating an overlay and sharing with others ...

Understood, and to enable it, one would have to re-compile the kernel?

Or I can just download a patched DTS and compile it to DTB?

 

Thanks for the prompt reply.

Even easier than that : decompile DTB currently present on you board, edit the resulting DTS by changing "status" node of "spi-gpio" to "okay" instead of "disabled", then recompile DTS into DTB.

OK, thanks, will try this!

Ok, switched to nightly, patched the DTB and now I have /dev/spidev0.0 and 0.1.

Thanks, guys!

Could you please post the steps how you did it? I am have similar issue.
