ESP-PROG debugger not working

[finster]

Hello,

I’m trying the ESP-PROG debugger for the first time wth a TTGO. I managed to upload using the program port connected to TX and RX. However when I try to run the debugger I get the error message shown below. I am powering the ESP32 from the ESP-PROG using the 5 volt pin and have connected to GPIO 12-15. Any help (wiring diagram ?) would be greatly appreciated.

thanks

Lolin D32 Pro - ESP-Prog

Hi, I have a Lolin D32 Pro and am trying to connect up the ESP-Prog Debugger to it and have some issues.I am a noob so bare with me. This was recommended as one of the boards to use on the PlatformIO site. PlatformIO Lolin D32 Pro It is based of of the ESP32-WROVER-B. On the D32 Pro & WROVER-B it says that the pins are as follows: [D32Pro-ESP32WROVERB] Sorry about the image. it will only allow a new user 1 image per post. I am at a bit of a loss how to connect the device up as some of th…

Failed to launch GDB - WROVER, ESP-Prog

Hi, I’m using an ESP32 WROVER with the ESP-Prog JTAG from espressif and it doesn’t work I’m getting the following output (below) but since I’m new to this I’m at a total loss to see what is the problem and what I can do.

Indicates that you have not run Zadig to change the change the JTAG channel of the FT2232HL to the WinUSB driver, as noted in the topics above.

I agree with @maxgerhardt: The problem is the FTDI driver, which needs to be unloaded with Zadig on Windows or kextunload on macOS. Currently, you have no connection between your computer and the debugger. So the wiring is not relevant yet.

Wiring information can be found here:

I also recommend to start with uploading your program via the debugger before trying to debug a program as it will verify that the communication from your computer via the debugger to the ESP32 is working. In order to do that, add this line to platformio.ini:

upload_protocol = esp-prog

Thanks everyone for your replies. I have it working now. I guess others are using ESP-PROG only for JTAG. I am using it both for uploading (The upload connector has pins for IO0 and EN) and for JTAG. My mistake was to reconfigure both ports. Now I use Zadig to configure only the JTAG port. I also specify the upload and debug ports in platform.ini.
