nRF52832 custom board designing

[Sairam]

 If i buy a raw nRF52832 chip and design the circuit by myself, how can i pre-programm the serial bootloader in it? So i could use the FTDI Basic (or an FTDI Basic -like device) to burn my program inside it. Thanks for your help!

Hi,

The nRF5 chips are shipped with an empty flash. That means that you must use an SWD programmer to do the initial flashing (of for instance a serial bootloader).

For that purpose, do I must need to add an SWD programmer supporting circuitry to my board..

Is there any other possibility, Because bootloader flashing is mostly one time requirement. So can you please help me regarding this ?

There is no need for an SWD circuitry (please see Reference circuitry). The only thing you need is access to the SWD pins. And this is something you typically want not only for production programming but also for debugging and perhaps production testing.

The only other alternative is to program the chips before you mount them on the PCB. See nWP027 - nRF52832 Production Programming for details.
