DirtyJTAG is a JTAG adapter firmware for cheap STM32 boards like BluePill or equally inexpensive ST-Link V2 clones that was developed to create an alternative to the cheap – but now obsolete – LPT Wiggler cables, and more expensive USB JTAG probes.
You’ll find the source, and documentation on Github. First, you’ll need to flash the firmware using the DFU method or an SWD programmer (for ST-Link) or USB to TLL debug board (for STM32 dev boards), before making the connection to the target board as shown below (for Bluepill).
Thanks to Zoobab for the tip.
