Hi all, I have a weird problem with my CAN-Software that worked a while ago. I have two machines, a desktop PC and a laptop, both have Ubuntu 9.04 with kernel 2.6.28-15 installes, both compiled and installed the peak- linux-drivers 6.11 correctly. (make && sudo make install).
I also installed today's version of socketcan (svn) on both machines. On both machines I can do 'ifconfig can0 up' without any problems. On the labtop, I can then do e. g. $ candump can0 or $ cansend can0 201#11.22.33.44.55.66.77.88 and things like that. It works. I checked that by connecting another PC (sorry, it was Windows XP) using PCan-View. When I try the same thing on the desktop PC, I get: $ cansend can0 201#11.22.33.44.55.66.77.88 socket: Address family not supported by protocol I installed the driver the same way as I did on the laptop and I have no other signs that anything fails. On the non-working desktop pc, 'cat /proc/pcan' gives this: *------------ PEAK-Systems CAN interfaces (www.peak-system.com) ------------- *-------------------------- Release_20090626_n ---------------------------- *------------- [mod] [isa] [pci] [dng] [par] [usb] [pcc] [net] -------------- *--------------------- 1 interfaces @ major 249 found ----------------------- *n -type- ndev --base-- irq --btr- --read-- --write- --irqs-- -errors- status 32 usb can0 ffffffff 255 0x001c 00000001 00000000 0000019f 00000000 0x0000 On the (working) laptop, it gives: *------------ PEAK-Systems CAN interfaces (www.peak-system.com) ------------- *-------------------------- Release_20090626_n ---------------------------- *------------- [mod] [isa] [pci] [dng] [par] [usb] [pcc] [net] -------------- *--------------------- 1 interfaces @ major 249 found ----------------------- *n -type- ndev --base-- irq --btr- --read-- --write- --irqs-- -errors- status 32 usb can0 ffffffff 255 0x001c 00000000 00000001 000001c0 00000000 0x0000 What can i do to investigate the problem in detail? I use two PCAN USB-Adapters (/dev/pcan32), one has firmware 0.7, the other uses a newer (2.?) firmware. exchanging them makes no difference. I appreciate any help. Thanx in advance.
