JTAGulator alternative based on Raspberry Pi Pico. Huge shout-out to Joe Grand for his JTAGulator project!

Installation

  • Download latest release version of blueTag ("blueTag-vX.uf2") from this github repository
  • Press & hold 'BOOTSEL' button on a Raspberry Pi Pico, connect it to a computer via USB cable & then release the button
  • Copy "blueTag-vX.uf2" file onto the newly detected flash drive (RPI-RP2) on your computer

Usage

  • Connect Raspberry Pi Pico running blueTag to your computer using USB cable
  • Connect Raspberry Pi Pico's GPIO pins (GPIO0-GPIO8 so 9 channels in all) to your target's test-points
  • Connect Raspberry Pi Pico's "GND" pin to target's "GND"
  • Open a terminal emulator program of your choice that supports "Serial" communication (Ex. Teraterm, Putty, Minicom)
  • Select "Serial" communication & connect to Pico's newly assigned COM port
  • blueTag supports auto-baudrate detection so you should not have to perform any additional settings
  • Press any key in the terminal emulator program to start using blueTag

Note: Pico's GPIO pins function at 3.3v. For connecting to devices running other voltage levels, use of external level shifter(s) will be required
