nRF52840 dongle "drag & drop" programming

[Robin]

Hello again Nordic Pro's,

This is a quick question that I have not been able to find the answer for before buying nRF52840 dongles to replace our nRF51 dongles.  We need several for our project and the pricing for the 52 is much better on the open market.

It is actually a multi-part question: 

Does the nRF52840 include the same "drag and drop" programming feature as the 51, and if so, is it directly supported for example apps under the delivered SDK v15.2, specifically, the ble_app_uart_c project using the keil IDE?

Thank you all in advance,

Robin @ TL

Nope.  However you can use nRFConnect desktop to flash it.

There is support for usb dfu with may help you.
A interface project can be found here.
But no out of the box solution to your question like Mojo said.

Can it be programmed via the Keil IDE interface?

Or a Segger Flasher?

Thanks

Robin @ TL

To use with Keil IDE, Crossworks, IAR, Eclipse, you need a jtag tool like this one  https://www.tindie.com/products/hnhoan/cmsis-dap-arm-debug-jtagswd-microsd-drag-drop/.

To use Segger software, you need the JLink.

We are talking about the same thing?

They have a footprint at the back for a j-link connector so yes. They also come stock with a dfu that is compatible with the above software.

It is an ARM JTAG/SWD standard coresight connector, not a jlink connector.  You don't need a jlink for that.  Any standard ARM compatible jtag can be used with it.
