Hi there, I have some problems of activating the CAN1 Bus for my BeagleBoneBlack. With 3.8.13 I activated the BUS according http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/ with the cape_manger and it worked quiet well.
Now I have installed 3.19 and work with dtb-rebuilder. What I have done so far: In the file *am335x-boneblack.dts *I have outcommented those two lines: *#include "am335x-can1.dtsi"#include "am335x-bone-can1.dtsi"* After make, make install (no errors), reboot modprobe, activation of can1 bus etc... I get 1:1 the same result in ifconfig as in 3.8.13(with the cape_manager). *can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 UP RUNNING NOARP MTU:16 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:10 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:71 * But when I look at the pins in* /sys/kernel/debug/pinctrl/44e10800.pinmux/pins* I get: *pin 96 (44e10980.0) 00000037 pinctrl-singlepin 97 (44e10984.0) 00000037 pinctrl-single* and for * /sys/kernel/debug/pinctrl/44e10800.pinmux/pinmux-pins pin 96 (44e10980.0): (MUX UNCLAIMED) (GPIO UNCLAIMED)pin 97 (44e10984.0): (MUX UNCLAIMED) (GPIO UNCLAIMED)* In 3.8.13 (where it works) I have those values: In */sys/kernel/debug/pinctrl/44e10800.pinmux/pins* *pin 96 (44e10980) 00000012 pinctrl-singlepin 97 (44e10984) 00000032 pinctrl-single* and for */sys/kernel/debug/pinctrl/44e10800.pinmux/pinmux-pins* *pin 96 (44e10980): 481d0000.d_can (GPIO UNCLAIMED) function dcan1_pins_s0 group dcan1_pins_s0pin 97 (44e10984): 481d0000.d_can (GPIO UNCLAIMED)* *function dcan1_pins_s0 group dcan1_pins_s0*So it looks like that the MUX has not been set. Anybody a Idea for a solution in the dtb-rebuilder or another idea? Thanks in advance!! Best greetings from Austria.
