Hm, could you please be more precise? What did not work which what version of the kernel, iproute2 and Socket-CAN? > any data sent or received on the can0 interface.

I'm running the modules from SVN rev 1064. I suspect either a electrical problem on the CAN bus or with the SPI transfer. Chris already commented on that latter. Here just some useful commands for debugging: - Run "candump any,0:0,#ffffffff" to check if messages are received. including error messages. - The "ip" program has some nice statistics information: "ip -d -s link show can0" Wolfgang. _______________________________________________ Socketcan-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/socketcan-users
