I am working with a BeagleBone Black rev C for a project using CAN. I am using the CBB-Serial-r02 cape because we need the UART features too. The problem is that CAN is not working. I did a lot of things to test it on a 3.8-rt kernel from RobertCNelson (which is only PREEMPT), but it didn't worked at all. Some things that I did:
1) Always modprobe the can modules (can, can-dev, can-raw) 2) Compiled and installed canutils, always using the "cangen can0" to test the can output 3) Always run "ip link set can0 up type can bitrate 125000; ifconfig can0 up" to activate can0 4) Installed the CBB-Serial-r02 dtbs from the official repository, even that the debian image that I used already includes it 5) Test the output with an osciloscope. I did the same test with an EzDSP 28335 and it worked, so it is not a problem with this part of the method 6) I tried to do a candump can0 with the DSP generating random data, but the candump didn't show any data I recompiled 3.14 kernel using the dtb-rebuilder (instructions on this tutorial: https://groups.google.com/d/msg/beagleboard/_9u1B6ZkgCU/K2ARgwfC490J) and enabling the DCAN1 (because DCAN0 disables the I2C used for capemgr) and it didn't worked too. Well, I ran out of options here. Some one is having problems with the rev C and CAN too or that is some problem with my method? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
