Configure Other JTAG Interface¶
Refer to section Selecting JTAG Adapter for guidance what JTAG interface to select, so it is able to operate with OpenOCD and ESP32-S2. Then follow three configuration steps below to get it working.
Identify all pins / signals on JTAG interface and ESP32-S2 board, that should be connected to establish communication.
MTDO / GPIO40
MTDI / GPIO41
MTCK / GPIO39
MTMS / GPIO42
Verify if ESP32-S2 pins used for JTAG communication are not connected to some other h/w that may disturb JTAG operation.
Connect identified pin / signals of ESP32-S2 and JTAG interface.
You may need to install driver s/w to make JTAG work with computer. Refer to documentation of JTAG adapter, that should provide related details.
