Confusing ERROR with ESP32PRG JTAG Adapter and HW Debugging (Read 208 times)

	There is a confusing problem with the HW debugging of a ESP32 DevBoard. I’m using VS community version 17.12.1 and the latest VisualMicro installed from the extension manager of the VS. Both are clean installations. I use the VM no Arduino IDE option. Build and uploading Arduino projects are running well. But if I try to use the HW debugging (the main reason why I bought the VM) it is hard to get it run. I use the ESP32 Prog adapter from Espressif as HW debugger and the Target Unit is a common ESP32 Devboard. If I use the following settings Debug: Hardware Debugger: ESP32 PROG Compileropt: No It does not work. I got an Error message “Unable to start debugging. Unable to establish a connection to GDB. Debug output may contain more information." The debug output you can find it below. The MicroBuild output I attached. BUT If I use the ESPESP32 DEVBOARD instead the ESP32 PROG as HW Debugger in the settings, it works more than less. Which is surprising, because the DEV BOARD is not the HW debugger. The debugger is the ESP32 Prog Adapter, which is connected to the DevBoard as a JTAG. Starting: -d2 -l 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; reset halt" Starting: lf-gdb.exe" --interpreter=mi -ex "set remote hardware-watchpoint-limit 2" -ex "mon reset halt" -ex "flushregs" -ex "thb app_main" -ex "c" exited with code 1 (0x1).

	Thanks for the report. The configurations for both are virtually identical (as both technically use the same FT2232H chip). Can you confirm which specific target ESP32 MCU is in use? Could you try attaching with the ESP-PROG, and then attach the OpenOCD Log from the build folder, and the output from the Output > Debug Window as well? Doc: Locate OpenOCD Log File

	The Target is a JOY-iT ESP32 Devborad with a ESP WROM-32 modue, but I have check it out with different Boards and modules, with all the same behavior. The DebugOpenOCD attached.

	Thanks for the log. There are some minor differences between the configurations for the probe, and we will update the ESP-PROG to use the same config as the DEVKIT in the next release once tested if it is proving more reliable, and aligns with the Espressif Documentation. Do you have any other issues when using the ESP32 DEVKIT configuration?

	Hello and thanks for the fast answer. I have not tested VM in detail yet. But what noticeable is, is that I must manually set the DevBoard in the Upload-Mode by pressing the switches on the board. That is not necessary if I use the same hardware combination on the same PC under PlatformIO and VSC. Mayby that’s works in this environment why I can choose there the correct hardware ESP32-PROG. Best regards
