Which pins should I take out in order to program the board?

[Sivam]

Hi,

I am planning on using nrf52832 for a beacon application. I happen to get a schematic and layout from Nordic website for development.

I am attaching the schematic along,

I want to know why there is no ground pin and Vcc pin in the schematic ?

which pins should I take out in the schematic in order to be able to program the nrf52832 board ?

Will I be able to use it if I develop the board from that schematic and layout itself or should I add anything else to it?

I am new to this and I have no idea on BLE and programming so I appreciate if anyone can elaborate the steps.

Thanks in advance.

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

Thank You so much Jorgen.

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

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.

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!

wait a minute - that was you, too!

Why are you repeating the question?
