How to test nRF52840 with CMW500

[TBui]

Hello,

We are currently looking for a way to test nRF52804 on our board with CMW500. From R&W video clip, they tested Nordic eval. board with USB connection. How do I make the same way from our board?

Thanks.

Hi,

Below is the video clip that how R&S tested your nRF52xx eval. board with USB connection. My question is how do you port that usb so i can make the same on our board? if you can share the schematic of the eval. board, that would be helpful.

Hi,

 

OK, I understand. The nRF52 runs the DTM example provided in our nRF5 SDK, using the 2-wire UART control interface. The UART lines are connected to the interface IC on the DK, where it is directed over the virtual COM port connection through the USB cable.

In order to use your own board instead of the nRF52 on the DK itself, you should cut SB9 to avoid powering the nRF52832. You can then hook your DUT onto the P0.06 and P0.08 headers on the DK. You can re-assign the UART pins on your DUT as you see convenient, but on the DK these are fixed as they are connected to the interface IC. For more information see the DK user guide. 

 

Best regards,

Andreas
