    Hi, in: https://visualgdb.com/tutorials/esp32/wroom/ SRST is listed as pin 3 of the JTAG connector.  But pin 3 is TRST I think, SRST is pin 15.

    The ESP32 docs say connect SRST to CHIP_PU as you do, but I’m just checking whether that should be SRST or TRST.

     

    Thanks, Joe

    Hi,

    In our experiments this worked differently with different JTAG debuggers (e.g. Segger J-Link vs Olimex), so we would advise trying both to see which one works with your device.

    Ok, thanks, I’ll try and put a bit of flexibility in my design.

    I think I saw another post by your team where you recommended the Olimex ARM-USB-OCD-H for esp32.  Is that still a good choice and what configuration of pins worked best for that model?

     

    Thanks, Joe

    Hi,

    Yes, any FT2232-based JTAG adapter (including Olimex ARM-USB-OCD-H) should work. For the exact pin configuration, please refer to the tutorial for the board you are using.
