canbus on skr pico error #3

Closed raptordemon closed 1 year ago

raptordemon commented 1 year ago

hi there, thanks for the write up. i followed all the insructions and i get the following error:

sudo ip link set up can0 type can bitrate 500000

output : Cannot find device "can0"

any ideas what i did wrong?

That generally indicates the OS can't see any CAN networks.

My guess is something went wrong with the firmware flash, or the Pico is not powered on.

I need to update the screenshots as there is now an additional line in the menuconfig for RP2040 devices.

It should be set like below:

Bootloader Offset (No Bootloader)

The bootloader offset should only be used if you have already flashed the device with Canboot first, which is a little outside the scope of my guide. Flashing canboot on a usb-canbridge device is still pretty finicky at this time and not something I would recommend for the new users this guide was targeted at.

If not any of that then it may be some other issue with the OS configuration.

What do you get when you run:

cat /etc/network/interfaces.d/can0

It should look like this:

allow-hotplug can0
iface can0 can static
    bitrate 1000000
    up ifconfig $IFACE txqueuelen 1024
