| Command | Description |
|---|---|
scan swd |
Attempts to detect a SWD device by brute-force pin scanning |
scan jtag |
Performs a JTAGULATOR-style brute-force JTAG pinout scan |
config |
Configure which GPIOs are used for scanning |
- The
scan swdcommand will try combinations of GPIOs to identify SWDIO and SWCLK. - You can select the group of pin to scan with
config(eg,. 1 3 5 7...). - The
scan jtagcommand tries all permutations of 4 GPIOs to detect TDI, TDO, TCK, TMS (and optionally TRST). - Original source for RP2040 https://github.com/Aodrulez/blueTag/, ported to ESP32.
- The features are similar to those of the JTAGULATOR.
