TERES-I USB debug cable

TERES-USB-DEBUG cable is now in stock. TERES has unique features to multiplex audio port between audio headphone output and serial console debug.

There are two ways to enable the serial debug via audio jack. First one is with teres1-debug on|off script and it will work until reboot:

sudo teres1-debug on

when you want to stop use

sudo teres1-debug off

this is good for try something while your laptop is working, but if you want to catch the early uboot messages you have to use another script:

sudo debug-switch.sh on

this will switch debug serial port permanently to audio jack until you execute the scriupt

sudo debug-switch.sh off

These scripts are included in the official image, but if you build your own you can install them from the GitHub sources
