BSP Questions

[Jim Robinson]

Hello,
First off I would like to thank the list for my first questions.
Here is round 2 ;-)
What I have been tasked here at work to do is get my SBS vg4 board
running with a minimal BSP.( i.e. enough to run hello world with a gdb
window.) I have Rtems 4.5.1-pre3 tools and the latest rtems-ss.
My question is, where should I start? I read the BSP and Device driver
manua, and it is a help, but not really helpful for starting. I am spilt

on using the mcp750 BSP or the ppcn_60x. Any suggestion?
I have attached a copy of the block layout of the board if it helps
(sorry about the size I tried to keep is small)..
Thanks,
James
