How to transfer code to external board by using uVision5

[JaeJin]

Hello,

I am currently utilizing the Keil uVision5 for debugging, but have confronted a problem which I cannot solve.

I managed to succeed in programming a soft device through the Keil uVision5, and was able to confirm that the code works in the nrf52832 bluetooth module in the development kit.

I also have a completed PCBt by reference from the circuit provided by Nordic.

My goal is to debug the code to an external board, but I am having trouble at this stage.

Is it possible to transfer the code into a soft device to an external board which I made by using the Keil uvision5 tool?

I am aware that we should connect the VDD, GND, SWDIO, SWCLK pin with the pin 20 in the development kit.

I have already read the documentations and instructions on your homepage online about the nRF52832, but I would like a more detailed instruction on how to perform this step.

Thank you for your help in advance.

(This is the external board which I made by using reference circuit.)

Hello,

You need to Connect VTG to the target board (or VDD on the DK) as well to enable programming on the out port (P20 or P19). So, it's sufficient to connect VDD, GND, SWDIO, SWCLK, and VTG, then you can program the external board the same way as you program the nRF52 on the DK.

When I complete to debug code to external board, can my mobile phone detect the Bluetooth?

If it is, what's the name of the Bluetooth module which is detected on my mobile phone ??

When I tried to give voltage, I gave it through USB cable which is connected to computer.

I'm not sure whether it is near 3.0V.

Is it right? Or do I have to do another thing for giving voltage source?

VDD on the DK is 3 V and is routed to the pin headers, see silkscreen.

The device name is set by the application code and is normally the same across boards.
