I guess what I am looking for is advise on the lowest risk, easiest to set up environment to setup that will just work.  Also advise on which kernel to use.   I don’t need a detailed tutorial but a high level direct that is known to work.  I am thinking of using either the secret lab tree or the Xilinx tree as recommended in Grants wiki page.  Should I just forget using XP and install a Linux (x86 processor so I must use cross tools)?   If so, what is the recommend distro and what version?

 

Thanks for all your sharing of experience.  I hope to contribute back as soon as I can.
