Yes, it is possible to run on your OK6410. I do not know the uboot
difference
between OK6410 and Tiny6410, so some paraments for configurating the timer
may be adjusted.

I use the original uboot that released by Friendly ARM for this board and I
think you may not modify the uboot. Anyway I'll do some work to migrate the
hardware configuation from uboot to rtems. The patch that I have mailed u
include a README
file. It shows how to configure, download to board and run.
