Flashing nrf52832 chip with ST link V2

[MikeLemon]

Hello, Is it possible to use this:

for flashing the nrf52832 chip? if so how? is this thing the same as Jlink?

Great and simple idea to do it didn't think about it before though I still don't understand how programming the chip with segger ide(programming wise) and can't find any guides for nordic type of programming so the project is stuck.

Hi,

I'd also like to ask, does the same apply for ST-LinkV3set?

Can I use it as well to program nRF52832?

Thanks

You can also try the IDAP-Link CMSIS-DAP. It comes with software to flash softdevice and dfu without the need of mergehex also supports parallel flashing for production.

Hi nirk,

where you able to figure it out? I created a custom programmer board using the STLINK-V3 module from ST.

When I want to upload a hex file to the attached NRF52810, I get the following output from openOcd:

C:\Users\david>openocd -f interface/stlink.cfg -f target/nrf52.cfg -c "reset_config none; program MyHexFile.ihex verify reset exit"

Interestingly, using an STLINK-V2 it works perfectly:

However, using the STLINK-V3 for debugging/flashing STM32 microcontrollers works perfectly.

Thanks in advance
