Hi Dennis - 


I tried to build the singlecell example with the SDK and it 
generated a bootable image for me.

Here's what I did (after exporting the OKL4_SDK_ROOT to the
correct SDK path):

glee at bob2 /scratch/glee/singlecell $ make
make -C hello KERNEL=micro BUILD=debug
make[1]: Entering directory `/scratch/glee/singlecell/hello'
cp hello.xml.in build.micro-debug/bin/hello.xml

For OK Linux I've been told that OK Linux is unfortunately not supported
on the 3.0 release for the gta01 platform at this time.
