Recommend nRF52832 custom board External Programmer?

[vishal]

Hi Sir,

We have designed custom nRF52832 board in PCB design layout have 4 Pin connector VDD, SWCLK, SWD, GND. I know how to use nRF52832 DK for programming. But for other user we need to only flash first time nRF52832 softdevice, bootloader, and application hex file into nRF52832 using nrf go studio. I do not need to debug custom PCB board. I know j-link programmer but it is very expensive only for flash hex file this mush too costly. I have found ST-LINK/V2 here I have few question on nRF52832 programmer:

1. Can i use this ST link for flashing boot loader, SD, application hex file using nrf go studio software.
2. If yes is it need to convert J link to ST link how detect my custom board in laptop using ST link.
3. Suggest me other nRF52832 programmer it will not more costly.

Thanks......

Hi Vishal,

ST link will not work with nRFgo Studio, or any of our other development/pragramming tools. Our tools are created to work with Segger J-Link, as this is the only programmer/debugger solution supported by Nordic. If you want to use ST-Link for flashing, you need to use some 3rd party solution like OpenOCD etc.

If you search DevZone or Google, you will find multiple post how this can be done. If you want a simple solution for both programming and debugging/development, that works with all our development tools, the nRF5x-DK is the best and most cost-effective alternative. As mentioned, the license of the OB debugger on the DK does not allow you to use it for production programming, but I don't think you would use ST-Link solution for this either.

Good luck!

Best regards,

Jørgen

I recommend that you have a look at this page about production programmers and tools. You should contact Segger for information about which programmer is best for your needs.
