    maaxboard with waveshare rs485 hat

    harmey

      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
