I've tried to start from /proc/config.gz which is a 3.1 config file but the resultant kernel compiled on the card won't boot on the CARMA cards. Thanks in advance for any help you can provide.

Spencer, which 3.8 kernel are you attempting to use?

As Peter mentioned, we don't support CARMA upstream at the moment.
However, in theory, you should simply need to write a device tree file
to enable the upstream kernel to boot on CARMA.

(arch/arm/configs/)tegra_defconfig is the .config file for Tegra in the
upstream kernel. It should enable pretty much anything Tegra-related,
and should be suitable for your use once you've written a CARMA device tree.

You might also want to consider porting upstream U-Boot, and creating a
configuration file for cbootimage-configs:

http://nv-tegra.nvidia.com/gitweb/?p=tools/tegra-cbootimage-configs.git;a=summary

so that you can use a completely Open-Source flashing process.
