Re: [Gumstix-users] Has anyone successfully built an image for Connex boards using current OE repo?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I don't know of any reason I would *need* the newer kernel - I'm more
interested in staying on top of patches to the rest of the packages.  Is
there any reason I couldn't run the old kernel with a filesystem image built
from the new repo?

I've poked around the recipes but I can't figure out how to reduce the
kernel size.  It's currently about 1.2M, and the Connex board is set up to
allocate 1M for the kernel.  If someone could point me in the right
direction I'd love to either increase the kernel size allocation or decrease
the compiled kernel size...
