I have the following tools:

nRF52-DK
VS Code v1.42.1
PlatformIO v3.1.0

My simple project is unable to communicate with the nRF52 board through the debugger.
Here is some build output. Note the reference to "NRF52832"

Processing nrf52_dk (platform: nordicnrf52; board: nrf52_dk; framework: mbed)
Verbose mode can be enabled via `-v, --verbose` option
CONFIGURATION: docs.platformio.org/.../nrf52_dk.html
PLATFORM: Nordic nRF52 4.0.0 > Nordic nRF52-DK
HARDWARE: NRF52832 64MHz, 64KB RAM, 512KB Flash

Is there a tutorial on getting started? Do I have an incorrect project setting?

[env:nrf52_dk]

platform = nordicnrf52

framework = mbed

board = nrf52_dk

I'm getting:
Failed to launch GDB: .pioinit:13: Error in sourced command file:
Remote communication error. Target disconnected.: Success.

Please install J-Link driver docs.platformio.org/.../jlink.html

Thank you. I did not have the tool-jlink package installed initially. I did configure upstream environments in my platformIO.ini and somehow managed to get the jlink drivers installed.

I should be able to flash/debug using just the USB SWD interface correct? I see 3 Segger Windows Device driver packages installed on my Win10 desktop

Do I need to invoke the JLinkGDBServer? I'm using the following JLinkGDBServer -If SWD -Speed 4000 -Device nRF52
I get an error "No emulators connected via USB". I get the same error when running from the IDE without the GDBServer. My nRF52 is plugged into a USB connection using the USB cable I received and the LD5 LED is flashing

I don't need to setup debug headers or another other form of JTag interface, correct? Help is greatly appreciated.

Sorry, this is our issue and has been just fixed. Could you try this configuration?

```

[env:nrf52_dk]

platform = github.com/.../platform-nordicnrf52.git

framework = mbed

board = nrf52_dk

```

Does it work?

[TerryMcP63]

Yes!
Thank you SO MUCH!
