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???

but i'm not experienced enough on this..

Armbianmonitor:
Hello All,
I'm trying to set-up MCP2515 on 8mhz on orange Pi one on SPI0
running recent installed Armbian 5.9 / Linux 3.4.113-sun8ican bus support orange pi zero
i was reading trough above for pi Zero and trying get the unit up and running, but no luck till now,
CAN unit is modifed, so 3v3 for mcp and 5v for can tranciever, connections:
pin1 3v3 power on vcc for mcp2515
pin2 5v power for cantranciever
pin6 gnd
pin19/PC0(GPIO Orange PI) MOSI - (MCP2515<->CAN) SI
pin21/PC1(GPIO Orange PI) MISO - (MCP2515<->CAN) SO
pin23/PC2(GPIO Orange PI) CLK - (MCP2515<->CAN) SCK
pin24/PC3(GPIO Orange PI) CS - (MCP2515<->CAN) CS
pin29 PA7(GPIO Orange PI) INT - (MCP2515<->CAN) INTconnected per i/o schematic from: Pi one GPIO
overlay for mcp2515
in folder boot/user-overlay --> sun8i-h3-spi0-mcp2515.dtbo

[ 0.629394] spi spi0: master is unqueued, this is deprecatedSeems i would have something wrong in armbianenv.txt / what do i have wrong in overlay..
some good direction pointer were really appreciated..
