    Hello,

     

    I’m trying to flash/debug an ESP8266 ESP-07 module with a 4 mbit flash. I use the FreeRTOS Webserver example, press debug and the following error is shown:

    I tried a genuine j-link PRO and j-link EDU, when opening Visual GDB Project Properties -> Debug Settings

    Debug Method: OpenOCD is selected. When clicking on Detect, “Detected Segger J-Link” is shown. When using the Arduino Toolchain the board works pretty well, power supply has enough output current. Both j-link work with STM32 cores without any problem. Does anyone have a tip what I’m doing wrong?

    Hi,

    OpenOCD needs a libusb-based driver for J-Link that is incompatible with the original J-Link driver. The easiest way to install it is using our USBDriverTool. You can also try configuring OpenOCD debugging with J-Link for an ARM project and click “Test settings” so that VisualGDB configures the driver automatically. We don’t have automatic driver setup for ESP8266 projects yet though.
