[okl4-developer] Debugging tips for a new platform

[Joshua Root]

Hi all,

I'm porting OKL4 2.1.1-fix7 to the Linksys NSLU2 (aka Slug), which is a 
big-endian XScale platform, IXP420-based. I've referenced the ixp4xx 
platform code from the old N1 version of L4, and the current pxa code, 
and have produced something which compiles and links, but the image 
produces no serial output when run.

I used the head.spp from pxa unmodified, would you expect that to work? 
Are there likely to be any issues with big-endianness outside the 
platform code? I've double-checked the KDB serial code and it looks 
right. Basically I'm looking for debugging tips. What am I most likely 
to have got wrong? :)

TIA,
Josh
