Hi All, it looks like Denx does have drivers for the CAN hardware on
the 5200. It appears to be a derivative work of Peak Systems
(http://www.peak-system.com) PCAN software. I skimmed the source code
and they have a driver that hooks the PCAN driver (they also support
devices such as the SJA1000 chip and a couple other products from
peak-system). The include in the source tree a command line app for
transmitting and receiving messages as well.

Based on skimming the source code and looking at the pcan web site it
appears to support 2.4 and 2.6 kernels, and the peak site indicates
that they support the PF_CAN (SocketCAN) stuff built into newer

I'm wondering, maybe Josh/Jamey could bring the flight computer on
tuesday and maybe we can play with this a little?
