Hi,

When I try convert ESP8266 project to standalone, I get a message:

Hi,

Thanks for reporting this, looks like our bug. Please try this build: http://sysprogs.com/files/tmp/VisualGDB-5.4.3.2348.msi

Thanks a lot.
But now debugging not working, the Segger J-Link debugging method has disappeared.

Hi,

Please try installing the experimental J-Link package from http://sysprogs.com/files/tmp/segger-dmsp-5.1preview1.vgdbxedp.

You can install it into VisualGDB via Tools->VisualGDB->Manage VisualGDB Packages.

Hi,

But I do not see the Segger J-Link debugging method.

Hi,

Sorry for the confusion. Could you please confirm whether the method disappeared for ESP8266/ESP32 devices or for ARM devices?

The ESP8266/ESP32 devices are not supported by the Segger J-Link GDB Stub, so the only way to use Segger J-Link with them is via OpenOCD (VisualGDB supports it). You can use this mode by selecting OpenOCD as the debug method and then picking J-Link as the interface (or switching to the “USB Devices” view and letting VisualGDB handle the debug method selection automatically).
