Flashing nrf52832 chip with ST link V2

[MikeLemon]

Hello, Is it possible to use this:

www.ebay.com/.../401088363326

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

[endnode]

Yes, ST-Link V2 supports SWD so it is usable to flash nRF52. There are several tutorials on this forum, just place ST Link to search (e.g. this and this and this). And no, it is not the same as SEGGER J-Link, SEGGER tools and DLLs won't work unless you connect it to SEGGER J-Link compatible probe with alternative FW (see more about it here). However you can use tools from ST Micro (these are also integrated with some IDEs like Keil) or some open source SW like OpenOCD.

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

I get an error saying no cortex M-SW device is found. any idea how to fix this ?
