ESP-Prog and HUZZAH32 Issues
Posted: Mon Nov 28, 2022 2:10 am
I am using ESP-Prog on a Windows machine.
I am using an ESP-Prog hooked into a HUZZA32 Feather (https://www.adafruit.com/product/3405) on a breadboard.
SIGNAL: ESP-PROG -> HUZZA32
MTCK: 4 - MTCK -> 13 - MTCK
MTDI: 8 - TDI -> 12 - MTDI
MTDO: 6 - TDO -> 15 - MTDO
MTMS: 2 - TMS -> 14 - MTMS
3V: 1 - VJTAG -> 3.3V
GND: 3 - GND -> GND
I’ve modified the JTAG driver to use WinUSB.
I am using the release of OpenOCD ESP32 v0.11.0 as found on github https://github.com/espressif/openocd-es ... 2-20221026.
Here are the steps I use to flash:
This is the response I get.
I’ve tried this many many times in various ways. One time it almost worked but I’ve never had a successful JTAG scan or file upload.
What is wrong here?
