Hi Experts,
I am very new to ESP32 development desperately help on JTag setup. I spend my whole day in futile attempt and running on circles.
I will very much appreciate if someone who has use JTAG in Wrover kit under Windows OS can suggest some pointers
I am able to build various ESP32 samples and mostly use serial out for debug. Now I like to use JTAG and bought Wrover Kit for the sole purpose of ease of setup install so I can focus on code. I am able to load and get serialprint to work via all paths - Arduino IDE, Eclipse as well as Windows (I am using Windows 10) command line using msys32\mingw32 build environment.. if only I can get JTAG to work
I will very much appreciate your suggestions and Thank you very much
Alok
Details below-
I followed step-by-step setup guide as well as other posts (ex:
https://www.ftdichip.com/Support/Docume ... s%2010.pdf) with no luck.
Steps:
1. When I connected the board via USB board both port shows up.
2. I added the 5 jumpers as suggested for JTag (see attached)
3. Run Zadig tool to reinstall the driver for interface 0 (see picture attached).
4. I installed OpenOCD tool
5. Run openccd tool as below but it keeps reporting device not found
There are no device/sensor attached to board and its running fine (I can see the serial print message from interface 1 of UART)
I am obviously missing somethings as this has been widely used with no issue. But I am not sure what is missing. I try to build openocd source under windows but run into many build issues there so stuck
My next attempt may be to switch to Linux and see I can get any better luck. I prefer Windows environment if I can make this work
