Digi CCWMX53

[Russell Haley]

Rui,

I've been able to build a kernel and upload it - again using a "Linux"
version of the CCWMX53 u-boot - but it didn't boot. I cloned your git repo
but I'm confuded (confused and befuddled or just a typo?) on how to cross
compile it. Do I set "devenvvar" (?) to somehow point into my latest
buildworld output and then just call make? Again I can only point to the
arndale board setup but even those instructions "feel" incomplete to my
novice brain. Any direction you could provide would be great. Here is my
latest boot output:
