There is an incosistency in your post, that you might not have noticed.

You write "i [sic!] am working on" and "i [sic!] want to" and "and write a".
Then you write incompatible information "give me some reference and some sample codes".

If you have reference code for interfacing your us os, then you will not be the one doing the work.
If you have sample code for can controller driver, then you will not be able to fullfill your want of writing that can controller driver.

By the way - what did you think about the sample code available on NXP:s web site? Or the Keil sample code? If you don't like this code - how will we be able to know what was wrong, since you never mentioned what worked/didn't work with that sample code.
