Hello everyone, I am searching for information on how to use CAN on the BBB across the internet and all the guides i could find won't work for me. I do all the installation and all, but when i check to see the slots i don't get anything, it's like the beagle hasn't configured the ports. the virtual can bus works, so the drivers are ok.. i did the overlay for the BB-DCAN1, compiled it, and still nothing. the closest i came to know something is right is when i use "dmesg | tail -n15" and get:
[ 2860.034007] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 [ 2870.064202] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 [ 2880.095569] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 [ 2890.126698] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 [ 2900.157938] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 [ 2907.178285] bone-capemgr bone_capemgr.9: part_number 'BB-DCAN1', version 'N/A' [ 2907.178475] bone-capemgr bone_capemgr.9: slot #11: generic override [ 2907.178526] bone-capemgr bone_capemgr.9: bone: Using override eeprom data at slot 11 [ 2907.178579] bone-capemgr bone_capemgr.9: slot #11: 'Override Board Name,00A0,Override Manuf,BB-DCAN1' [ 2907.178850] bone-capemgr bone_capemgr.9: slot #11: Requesting part number/version based 'BB-DCAN1-00A0.dtbo [ 2907.182418] bone-capemgr bone_capemgr.9: slot #11: Requesting firmware 'BB-DCAN1-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 2907.182517] bone-capemgr bone_capemgr.9: slot #11: dtbo 'BB-DCAN1-00A0.dtbo' loaded; converting to live tree [ 2907.183160] bone-capemgr bone_capemgr.9: slot #11: #2 overlays [ 2907.183385] bone-capemgr bone_capemgr.9: slot #11: Applied #2 overlays. [ 2910.189201] [drm:output_poll_execute], [CONNECTOR:5:HDMI-A-1] status updated from 1 to 1 this is half right as far as i could see in the installation guides. my goal is to set up the DCAN1 with pins P9_24 and P9_26 permanently so i wouldn't have to go to the terminal and do the "echo" thing every time i boot the beagle. does anyone have a simple guide for beginner like me? or could talk to me via the email (my mail is: [email protected]) and guide me? that would be awesome. by the way, i am going to send and receive that data with python-can. anyone has experience with it? how to init the can bus before using the send and recv of CAN messages? any help would be blessed, i am stuck after trying everything and not succeeding.. i couldn't get it to work. thanks! :) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
