The one that exist is : overlays=spi-spidev param_spidev_spi_bus=0 Also, your u-boot log is truncated, we don't see the part where overlays are loaded ...

jwhouwers Posted February 14, 2020 Author Share Posted February 14, 2020 Martin, thanks for the reply, changed per your comments, as no i did not write one, but same result on dsmeg as above.. looks like spi0 were not enabled, used the mcp2515 board earlier with arduino without issue's added the u-boot file, and dtbo overlay file..i was checking the overlay info from Armbian user-guide it made me doubt on the folder locations, after installing base image copied attached dtbo file to folder /boot/overlay-user or do i need to do something after copying???

You should try with Mainline "current" or "dev" images ... Link to comment Share on other sites More sharing options...
