BeagleBone Debug Console Stuff

Console access:

Use https://github.com/tio/tio/releases/download/v1.32/tio-1.32.tar.xz to download tio

Copy it into a random directory ( I used ~makeitlabs/code/c ).

Then:

• tar x tio-1.32.tar.xz

• cd tio-1.32/

• ./configure

• make

• ./src/tio -b 115200 /dev/ttyUSB0

When done, use  crtrl-t q to quit.

Console output;
