Basically, versatile express is not a board supported by the I-pipe
patch, so, the first thing is to check that the I-pipe port is working
correctly. For instance, I would run tsc -w first to see if the tsc
emulation is working correctly. Then you can use this document:
http://www.xenomai.org/index.php/I-pipe-core:ArmPorting
As a check list.
Also, some modifications would be needed to get it working in SMP mode.
This should be much easier to start with the I-pipe kernel for 3.4,
except for the "global timer" which seems not to be present on versatile
express, so, some code would be needed to skip the initialization in
gt_setup when we detect a processor that does not have a global timer.
