Problem partly solved: Wrong dtb-rebuilder used... I used dtb-rebuilder 3.14, but needed 3.19...
Now it works, but another problem appears. Candump works fine. I get the signals what I send from my PC. But I can't transmit any signals via cansend. After pressing Enter: No Error - Nothing happens. And after the cansend command I even can't use candump anymore. If have to "restart" the canbus when I want to receive any signals. Funny thing...
