ESP-PROG debugging problems
Nov 25th, 2019 at 4:51pm
Print Post  
I have connected an ESP-PROG debugger to an ESP-32 devkit device using the following pins:
TWS ->D14 green
TCK -> D13 purple
TDO -> D15 orange
TDI ->  D12 blue

GND to GND

the jumper is set to 3.3 V on the ESP-PROG

When i plug it in to the USB port i get the 2 serial ports generated by the ESP-PROG as per the Expressif driver instructions (I didnt need to install any drivers manually).

I follow the visual micro instructions and select ESP32 PROG from the list of hardware debuggers.

I click "Debug-> start debugging, the sketch uploads to the ESP32 and I get the dreaded: "unable to start debugging. Unable to establish a connection to GDB.." error. 


my debug output is as follows:
Starting: "C:\ProgramData\vmicro\tools\openocd-espressif-esp32-10.0.1\bin/openocd.exe" -d2 -l devkit-v1\Debug/HX711_basic_example.ino_DebugOpenOCD.log}" -s s/" -f s/interface/ftdi/minimodule-lowcost.cfg" -c "set ESP32_RTOS none" -f s/board/esp-wroom-32.cfg" -c "init"
Starting: c\1.22.0-80-g6c4433a-5.2.0/bin\xtensa-esp32-elf-gdb.exe" --interpreter=mi -ex "set remote hardware-watchpoint-limit 2" -ex "mon reset halt" -ex "flushregs" -ex "thb app_main" -ex "c"
"C:\ProgramData\vmicro\tools\openocd-espressif-esp32-10.0.1\bin/openocd.exe" exited with code 1 (0x1).



any tips would be appreciated!

Thanks for the detailed information.

From the output in the OCD Log it appears it cannot find the Debugger USB device.

Check the USB Drivers are installed for "Interface 0" of the ESP32-PROG device, using the Zadig tool - more detailed information is below:
