BBB找不到can0

已经按照http://blog.csdn.net/flymachine/article/details/7251061上面说的使能了，也加载了相应的内核模块

debian@arm:~$ dmesg | fgrep -i can

[ 3.101212] PM: Cannot get wkup_m3_ipc handle

[ 3.426797] [drm] Cannot find any crtc or sizes - going 1024x768

[ 33.484271] can: controller area network core (rev 20120528 abi 9)

[ 33.576377] CAN device driver interface

[ 33.669621] can: raw protocol (rev 20120528)

[ 33.848851] bus: 'platform': add driver c_can_platform

debian@arm:~$

BBB板好像是没有CAN的，即便你成功把CAN调出来了一用不了，这点要注意

另外，把完整的CAN的设备树贴上来，不然很难分析。

按理CAN是很容易出来的~

有can口的，外接个can收发器就可以，我用官方的镜像测试过，现在是下载内核，自己编译，然后can一直找不到
