Cross compile python wheel for jetson nano

I have been trying to cross compile python wheel tensorflow lite for Jetson nano device.
referring following link:

ARM cross compilation

tensorflow/tools/ci_build/ PI-PYTHON38 \  tensorflow/lite/tools/pip_package/ aarch6

Host device : Ubuntu 20.04 LTS

But soon after compilation starts, at around 20 minutes, my screen freeze, I had to shutdown my device, Do i need to make any changes before starting compilation.
