I have posted all the steps required to build TensorFlow on Jetson TK1 at:
It takes a long time to build and it is really pushing the Jetson TK1 to its limits, but it can be done.
I have also updated the wheel file at https://drive.google.com/file/d/0B1uGKNpQ7xNqZ2pvSmc3SlZJS2c/view?usp=sharing
if you are just interested in installing it. The build requires CUDNN 6.5 but it is using the standard 6.5 toolkit.
