MCP2515 problem

[MikeBaxter]

Hi, i want to connect a MCP 2515 (the small modules for arduino) to my tinkerboard "Armbian 22.02.1 Hirsute with bleeding edge Linux 5.17.5-rockchip"

I have enabled the SPI0 (and UART1) directly from armbian-config, I have disabled all the other peripherals.

The connections are these:

 

INT   -------------> pin 32

CLK -------------> pin 11

SI ----------------> pin 13

SO --------------> pin 15

CS --------------> pin 29

 

in : /boot/armbianEnv.txt

 

i add this:

user_overlays=spi-mcp251x

 

but it don't work and i can't find a guide for this board

 

thanks a lot for your help

i change the armbianEnv:

verbosity=1
bootlogo=false
overlay_prefix=rockchip
overlays=spi0 spidev0 uart1
rootdev=UUID=0b9d8e40-3bf5-4cc1-a228-484d182cb585
rootfstype=ext4
##param_spidev_spi_bus=0
user_overlays=spi-mcp251x
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u
 

 

and this is the result of armbianmonitor -u:
