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 July 12, 2018 at 20:24 #21358 supportKeymaster 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.

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 July 12, 2018 at 22:58 #21363 supportKeymaster 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. July 12, 2018 at 23:41 #21364 JoeWrightParticipant OK thanks.
