Hello all,

I'm working on an evaluation board, M5235EVB, from Freescale. I got a
uclinux distribution (uClinux-dist-20051014.tar.gz) and have problems
using the CAN driver (I'm using can4linux come along with the
distribution).
Observing the driver source, I could see codes for mcf5282 not for
mcf5235. I have tried the make menuconfig again and I could only see the
option ColdFire Flex CAN under the can4linux Support option, nothing
specific to mcf5235. I have made a quick look at both reference manual
(MCF5235 and MCF5282) and I could see that some of the register
addresses and size are different. For eg the size of the CANMCR register
of MCF5235 is 32 but in MCF5282 it is 16. The address of the IFLAG
register is also different. Does the can4linux support MCF5235? I've
searched in google but everyone tells about MCF5282. Could any one of
you please help me? 

Any help will be appreciated,

Firos
