Can JTAG Pins be Rerouted?
Posted: Wed Jan 11, 2023 10:07 pm
Hello All,
Can ESP32 JTAG pins be rerouted? I just received 2 development boards that have an OLED attached. The device uses GPIO15 as one of the pins to control the display. I want to use the ESP-PROG to interface with the board to allow debugging, but the JTAG connections use GPIO 12 through 15. I know that several of the internal peripherals can be routed to various pins, so I wanted to know if it is possible to reroute the JTAG DI0 to another unused pin besides GPIO15 before I go out and search for yet another flavor of a ESP32 development board.
Thank you very much for your valuable time!!
