Hello there,
recently got a few maaxboards with waveshare rs485 hats (https://www.waveshare.com/wiki/RS485_CAN_HAT ) for a school project but i cannot seem to get them to play nice with each other.
I connected the board and ran the command:
ifconfig -a</p>
but unfortunatly it doesn't recognize the hat.
I've been told i need to create a new dtb overlay but i have no idea where to start with that...
I also tried to use the mcp2515-can0.dtbo from the rpi 3b+ (on which the hat does work) and edited the uEnv.txt by adding:
dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000
could someone help me out with this?
kind regards,
Harmey
