MCP2515 SPI setup - Raspberry Pi Forums

hey guys,

i'm trying set small can network reader raspberry pi 3.

should have recent updates..

code: select all

pi@raspberrypi:~ $ uname -a linux raspberrypi 4.4.11-v7+ #887 smp thu may 19 16:24:03 bst 2016 armv7l gnu/linux 

i've been following guide pretty closely http://skpang.co.uk/blog/archives/1165

i've installed updates, lsmod looks like:

code: select all

pi@raspberrypi:~ $ lsmod | grep spi spi_bcm2835             7286  0 pi@raspberrypi:~ $ lsmod | grep mcp mcp251x                 8502  0 can_dev                 9561  1 mcp251x 

and, config.txt looks like:

code: select all

dtparam=spi=on dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25 dtoverlay=spi-bcm2835  dtdebug=1

however, when try bring can interface, error.

code: select all

pi@raspberrypi:~ $ sudo /sbin/ip link set can0 type can bitrate 500000 cannot find device "can0"

looking @ sudo vcdbg log msg, found it's not loading spi-bcm2835.dtbo overlay.

code: select all

001722.109: dtdebug: opened overlay file 'overlays/mcp2515-can0.dtbo' 001735.551: loaded overlay 'mcp2515-can0' ..  001811.086: dtdebug: failed open overlay file 'overlays/spi-bcm2835.dtbo' 001811.100: failed load overlay 'spi-bcm2835' 

looking in /boot/overlays/ folder, .dtbo found! why newest firmware not have file, , can it?
