I try to debug my Cobra II via Serial, because I want to use the USB Client Feature.
I have a COBRA II Extender connected to the board.
The “Serial mode” pads are connected.
I have connected a USB-Serail module to port 5 which appears as COM4 in Device Manager.
When I connect the USB Client connector to my PC no device shows up in Device Manager anymore (which is correct I assume, because there is no USB-Client code on the board yet)
It’s a Cobra II NET, with FW 4.3 Beta 3 and nothing else connected, but power (15V DC) and USB-Serial module.
But when I try to deploy, I get the following error:
Looking for a device on transport 'Serial' Starting device deployment... Iteration 0 Opening port \\.\COM4 Attaching debugger engine... ... cannot attach debugger engine!
Any ideas what could be wrong.
I even tried with a USB-Serial SP module, which was working for my Medusa Mini.
I also tried manually resetting the board while VS looks for the Debugger.
