Show must go. I used a temporary poor man's solution - timer interrupt and pooling hardware IRQ GPIO. But the problem still exists. Sorry, I'm not a kernel developer. I used this board (pcDuino3nano) in my project with preinstalled lubuntu, hardware interrupts (2 GPIO's) were supported in it. Now I migrated to Armbian because of lots of new features in it. I had to patch kernel to enable SPI support, I did it myself. But the hardware GPIO interrupts are not supported in Armbian in the old way. Looks, like I need to modify .dts file or smthg else, but I cannot do it myself without guidance or example at least . Any help is welcome.

I am sorry to disturb you in such way. It goes only about question: is it available in Armbian's mainline and I'm missing smthg, or I have to patch .bts file in some way and recompile kernel. Once more, I'm sorry...

Is there the support for hardware interrupts on pcDuino3nano gpio2(GPIO231) or gpio3(GPIO230) in Armbian mainline, as it worked on Lubuntu ? How can it be installed/enabled ?

Is there anywhere examples, samples or tests for CAN driver using MCP2515 controller via SPI ? Board is Pcduino3-nano with Armbian5 & Mayby, any other CAN driver usage demo or samples on Pcduino3-nano ?
