As a beginner, no.

Again, you really need to get an nRF52DK - and learn the basics on that.

Then, once you have gained sufficient knowledge and experience on that, you will be in a position to work out how to hack a Nucleo board.

But hacking an unsupported, non-standard approach is really not a great way for a beginner to start!

Alternatively, you might want to start by learning the basics of microcontroller development on your Nucleo board. It is certainly a simpler platform.Then come back to Nordic & nRF52 when you've gained sufficient knowledge and experience on that.

As with anything, you need to learn to walk before trying to run a marathon!

The page you linked say the board have a on-board debugger that can act as a standalone ST-LINK/V2 debugger:

Nucleo features

On-board ST-LINK/V2-1 debugger/programmer with SWD connector
- Selection-mode switch to use the kit as a standalone ST-LINK/V2-1

I know some people have been using this kind of debugger together with OpenOCD software to program nRF5x ICs, but this is not something we provide support on, and you will have to figure it out by yourself.

For getting started with our products, I would highly recommend getting a nRF52 DK or nRF52840 DK. These boards have on-board J-Link debugger, that can even be used to program external boards/devices.

Thank You so much !! I will look into that.

I am in an internship and the company assigned me to work on nordic BLE beacon. So only am researching though.

I have a ST nucleo board.

Will i be able to program the chip with that ?

Then you are diving in at the very deep end!

You should probably spend some time learning the basics before trying advanced stuff like Bluetooth!

If you don't get the answer you're looking for, then explain what it is that you are looking for!

If you just keep repeating the same question, then you're going to keep getting the same answer!

Plus it makes looks like you're not listening.

To do that, you should certainly start with the Dev Kit!

This is exactly the reason why Nordic - and all the others - make Dev Kits: so that you can learn & experiment on a known-good platform, complete with all the support for programming, development, etc.

Once you have gained sufficient experience & understanding on the Dev Kit, you will be ready to start your own design, if required...

Cortex-M device I don't have any idea on that either. Am new to electronics field.

Yeah because I didn't get the answer which I was looking for. Which Horgan gave, I needed a more clear answer like that, I was confused. Sorry for the trouble

I am making a beacon to understand how it works for now. After that I might use it for some other applications.

[quote userid="74208" url="~/f/nordic-q-a/39452/which-pins-should-i-take-out-in-order-to-program-the-board"]I am planning on using nrf52832 for a beacon application ... I am new to this and I have no idea on BLE and programming[/quote]

That sounds like a pretty fundamental prerequisite!!

Would you not, then, be better off using one of the many ready-made, ready-to-go Beacons ?

wait a minute - that was you, too!

Why are you repeating the question?

[quote userid="74208" url="~/f/nordic-q-a/39452/which-pins-should-i-take-out-in-order-to-program-the-board"]I want to know why there is no ground pin and Vcc pin in the schematic ?[/quote]

I can see both in the schematic you posted:

New to what, exactly?

As noted, as far as programming goes, this is exactly the same as any other Cortex-M device!

The chip is blank when delivered. You will need a programmer/debugger supporting SWD interface for flashing it the first time. You can flash the chip with our DFU Bootloader, to support upgrading the firmware through serial (UART or USB) or BLE.

Thank You so much Jorgen.

Is there any other way to program it ? I mean any other tool ? Hardware ?

Hi,

Please have a look at the nRF52832 Pin assignments documentation. VDD is power supply pin, VSS is Ground pin. The bottom of the chip is alos used as ground pad.

For programming, you need SWDCLK and SWDIO pins, in addition to VDD and Ground. You need to connect these pins to an external programmer/debugger that supports SWD interface, like SEGGER J-Link, to flash the chip.

Best regards,
Jørgen
