Flashing code into NRF52832 ICs quickly

[SaiTeja]

Hello , What is the preferable way to flash code into NRF52832 IC during mass production? Flashing the code into custom IC with NRF52-DK in time consuming process.

And also Is there any way to generate and flash hex code into NRF52832 ICs rather than flashing code from keil software?

Yes, loading the code takes some time. The only way how to speed it up is to use higher SWD clock. E.g. SEGGER J-Link supports 50MHz or even higher clocks and it seems to work well (at least with nRF5x DK boards). Now if you really want to speed the process you can do pre-programming in the socket so the final time on the production line is shorter (that's what usually matters). This is standard technique so your professional partner for PCB assembly line should be able to advise or directly offer such service.

To your second question: no one would ever flash the board in production from Keil;) There are so many options for JTAG/SWD programmers, some of them just professional versions (like J-Link line from SEGGER) some even industrial/mass production grade (see some examples on Nordic Infocenter). Again Google and some knowledgeable consultant are your friends if you are in doubts.

Can you suggest a way to flash application hex code directly into NRF52832 boards?

What do you mean? There is the only way to flasg anything to nRF5x chips when they come from Nordic and that's SWD programming. So take any you like based on price and features. If you don't know then take SEGGER.

Can we flash hex file into NRF52832 custom board from NRF52DK? If yes, please help me in this regard.

Surrly you can, it has SEGGER J-Link OB so you have at least 3 options: SEGGER J-Link SW pack, Nordic nRFgo Studio or Nordic nrfjprog command line utility from NRFTOOLS pack. All these have comprehensive manuals so just read them and use.
