CAN IoT Card driver


Progress update :

echo 13 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio13/direction
echo 1 > /sys/class/gpio/gpio13/value

pin SPI1_CLK / SPI1_MISO / SPI1_MOSI follow the state on GPIO13 on WP76…

SPI bus seems don’t work. mcp2515 is not probed.

Asyal any idea ?


@Francis.duhaut I’ll build this on Friday and get back to you with the right steps.


ok thanks :slight_smile:


@asyal any progress on the CAN for the WP76 ?


I ran into the same issues you did and will work on resolving it next week.


Thank’s a lot for your help.

  1. Reflash new image with CAN driver module support to the target board
    FDT command: fdt yocto_wp85.cwe

When I run it I get: command not found: fdt
What do I need?


Use :
fwupdate download yocto_wp85.cwe


Thanks, Francis, I got one step closer but I am a bit confused about next one. When should I remove the card and how? I tried different ways but
echo 2 > /sys/class/gpio/export
gives me
sh: write error: Device or resource busy
