^exitHi,
This looks like a known issue of the ESP32 OpenOCD. Please see this thread for details.
In order to flash the application via USB as the thread suggests, you can use the “Program FLASH Memory” command in the context menu in Solution Explorer (you would need the make sure the virtual COM port used for programming has the correct drivers installed).
Sorry, but I continue to have the problem also after to have programmed by USB – COM bootloader and partition table..
The problem was born after to have updated last Open OCD proposed on VisualStudio ….then I removed that Open OCD but the problem remained ..
Hi,
It could be a bug in a particular OpenOCD version then. You can always revert to the previous version as shown here: https://visualgdb.com/support/oldpackages/
Restoring the previous OpenOCD and doing a full FLASH erase via esptool.py should completely reverse any changes done by the newer OpenOCD.
I restored the previus openOCD but I have the same problem 🙁
Is it possible to understand something from Error log below?

^exitHi,
The log comes from the OpenOCD tool, that is maintained by Espressif, so we do not have much insights into it. You can try downloading OpenOCD from Espressif directly, running it manually per their instructions, and checking if it works. If it fails with the same error, please consider posting on the Espressif’s forum, perhaps they have a better idea of what’s going on.
If OpenOCD works when running it manually, but doesn’t work with VisualGDB, please let us know and we will walk you through getting it to work with VisualGDB as well.
Espressif forum told me that OpenOCD looses offset of my application that is necessary to give this information to OpenOCD with:
-c “init; halt; esp appimage_offset 0x20000”
But where and how in VisulStudio can I give to OpenOCD this information?
In the past this operation wasn’t necessary….
Hi,
It should normally not be necessary – in our tests OpenOCD managed to find everything automatically. Either way, please follow the steps below to resolve it:
- Try starting a debug session. Take a note of the OpenOCD command line at the beginning of the Debug->Windows->VisualGDB Output window.
- Try adding -c “esp appimage_offset 0x20000” at the end of the Command Line setting under VisualGDB Project Properties -> Debug Settings -> Advanced Settings (bottom of the page). You should not normally need the “init; halt” part.
- Try starting another debug session. Take a note of the updated command line in the VisualGDB Output window.
- If this does not resolve the problem, please try adding the “init; halt” part as well.
If the problem is resolved, please share the full command line so that we could look further into it and make sure VisualGDB handles it automatically.
This is my initial OpenOCD start command:
C:\Users\bope02\AppData\Local\VisualGDB\EmbeddedDebugPackages\com.sysprogs.esp32.core\bin\openocd.exe -c “gdb_port 54033” -c “telnet_port 54031” -f interface/ftdi/esp32_devkitj_v1.cfg -c “adapter_khz 3000” -f target/esp32.cfg -c “echo VisualGDB_OpenOCD_Ready”
Open On-Chip Debugger 0.10.0 (2022-05-03)I’m sorry but after added the command line as you indicated (see attached file VisualGDB_Debug.jpg) when I start DEBUG immediately I always have an error “Target not halted”.
Even If I disconnect and then riconnect USB I continue to have this error.
In this case logs are:C:\Users\bope02\AppData\Local\VisualGDB\EmbeddedDebugPackages\com.sysprogs.esp32.core\bin\openocd.exe -c “gdb_port 54450” -c “telnet_port 54448” -f interface/ftdi/esp32_devkitj_v1.cfg -c “adapter_khz 3000” -f target/esp32.cfg -c “esp appimage_offset 0x20000” -c “echo VisualGDB_OpenOCD_Ready”

Then I tryed to add “init; halt” but without any result but with a different error message:

Unexpected command line argument: “init;Hi,
Sorry for the confusion. The correct command line should be:
C:\Users\bope02\AppData\Local\VisualGDB\EmbeddedDebugPackages\com.sysprogs.esp32.core\bin\openocd.exe -c “gdb_port 54502” -c “telnet_port 54500” -f interface/ftdi/esp32_devkitj_v1.cfg -c “adapter_khz 3000” -f target/esp32.cfg -c “init; halt;esp appimage_offset 0x20000” -c “echo VisualGDB_OpenOCD_Ready”
You can also do this:
-c init -c halt -c "esp appimage_offset 0x20000"
ON your previous message I see different gdb_port and telnet_port from mine….Have I to change ? Where I can change them?
If you are changing the command line in VisualGDB project properties, rather than running VisualGDB manually, you do not need to specify the gdb port. Simply use -c “init; halt; esp appimage_offset 0x20000” instead of init; halt” -c “esp appimage_offset 0x20000” that you tried before. Please also make sure there is a space before -c.
