uEnv.txt not having any effect

Solved this myself. Stupid problem. I had duplicated my uEnv.txt into my Angstrom partition when I was learning how u-boot worked (obviously still am).
I was editing the wrong version.
Once I moved back to uEnv.txt on the actual boot partition (not the /boot folder on my Angstrom partition) I started getting my DSP code to run.
