How to JTAG debugging multiple ESP32-WROVER Board.

[kevinn]

Hi,

I need to JTAG debugging two ESP32-WROVER board on the same computer.

But, it seems that VisualGDB OpenOCD always select the same board.

My question is how to configure VisualGDB to specify a speect ESP32-WROVER board to use?

Thanks,

Hi,

Please try creating a temporary copy of the interface configuration file (e.g. esp32_devkitj_v1.cfg) and add the ftdi_serial command there (OpenOCD should show the serial numbers of connected devices if multiple matching adapters are found), then specify the copied script in the Debug Settings.

Normally VisualGDB should do this automatically, however we have not explicitly tested this with the ESP32 devices, so minor adjustments might be required. Feel free to let us know your observations and we should be able to update VisualGDB to do this automatically.
