Hello. Maybe would you try CanFestival
http://perso.wanadoo.fr/edouard.tisserant/CanFestival/ This is a CanOpen master but the Can driver is usable as stand-alone and provide a rtl-PosixIO interface. This is known to work on 2.2 -> 2.4 kernel with Rtlinux 2.x ->3 Actualy it only support Adlink PCI-7841 SJA1000 based board, but porting it to other hardware should be easy (hardware spec are in separate files). Be carefull... If you plan to stop trying this code just for a little compiler error, don't try it, you will certainly get some errors (missing path because you didn't read the doc, and all...). If you want something where you just have to clik and play, buy it ! Btw Heinz Haeberle drivers seems OK, but you have à #define problem about SMP (Pentium II doesn't mean 2 CPU... ;o)). Just try to have look in the source.
