I missed something, is your kernel in the 512k romimage?

so you'll need etherboot.

the smartcore-p5 I think builds a 256KB romimage.

IDE-attached CF works now for me on several platforms. 

I'm intrigued though, how small is your kernel again?

Are you sure that a 512KB flash won't work in your board? the address 
lines might be there.
