Hey Jason,
Try following these steps:
1. go to the linux source in the SDK
cd ti-sdk-am335x-evm-06.00.00.00/board-support/linux-3.2.0-psp04.06.00.11/
2. set up your toolchain path
export PATH=$PATH:/home/user/ti-sdk-am335x-evm-06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/
3. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig
4. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
5. set your options in menuconfig and save them
6. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage
7. grab uImage from arch/arm/boot and copy to your boot partition.
Let me know how it goes.
