Hi xingqing6210,

I am very sorry for this delay reply. I was very busy with my current work.

I believe that your rpi is lacking of ieee802154 modules. You should insert them before load the dw1000.ko. Please input following:

sudo modprobe mac802154 sudo modprobe ieee802154_socket

Regards

Got it , thanks
