Mainly due to some frustrations around opencv Python support in Angstrom, I

Robert Nelson's excellent tutorials and scripts, but need some guidance in
adding my own kernel modules and device trees. I have already successfully
built them under Angstrom/bitbake, but cannot determine the preferred or
"correct" workflow for Debian. Any help would be greatly appreciated.
Hi Dave,
What kernel modules/device tree's do you need enabled?
Thanks for your quick reply.
These are modules/dts that I have written to support a UPS/watchdog cape
I am developing. They are building and working fine with the 3.8
Angstrom kernel using the attached bitbake recipe. My question is what
are the magical incantations I need to build these outside the kernel
tree? I suspect there is a "correct" way to do this under Debian, rather
than me re-inventing a wheel.
Regards,
Dave.
For the bone, the kernel script can be found here: (it's 99% source
identical to angstrom's 3.8 tree)
