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

Intel made nice video tutorial how to use OpenOCD and our JTAGs with their SoCs! This explains the frequent purchases they do from many Intel locations all around the world of ARM-USB-TINY-H , ARM-USB-OCD-H and ARM-JTAG-20-10.

Searching bit more there is application note How to setup ARM-USB-OCD-H with Intel Quark SoC X1000 and tutorials about Low-cost UEFI debugging options for Intel and How to debug Linux Kernel on Intel Quark

ESP8266-EVB support for JTAG development with flash load, breakpoints, disassembly, step debugging in Visual Studio C/C++


Ivan Shcherbakov @SysProgs shared interesting article. He wrote support for ESP8266-EVB to VisualGDB Visual Studio plugin for embedded software development in C/C++.

With this plugin you can use JTAG to debug code in ESP8266, also to set breakpoints, view the disassembled code etc. This adds new level for professional developing using ESP8266.
