Hi, We have developed CAN hardware based on the Philips SJA1000 controller hooked to a MPC8xx based processor board. Now we want to write driver support for it. My first try was lincan-0.3.1, which seemed quite well written at first glance. Porting was easy too, and the driver works fine on our board with the latest kernel (2.6.14). But.... this driver lacks a proper way of checking the status of the CAN controller from userspace :-( Not that nice after all!
Then I see on the DENX website, mention of Rubini's OCAN (mostly useless to us), and Peak's PCAN drivers (there is a port for MPC5200 on DENX's site). No word about lincan, though. The reason I suppose is, someone already figured out that lincan is not a good choice for whatever reason (status reportability ??), right? Before beginning to re-invent wheels and re-discover known problems in certain CAN driver architectures, could someone please point me to the right place to start looking for answers (if that place exists) or just give the answer, opinion or experience with one of PeakCAN, lincan, can4linux, etc...? I am again puzzeled about which way to go. Thanks for any advice, -- David Jander Protonic Holland.
