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

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

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,

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

Can I use it as well to program nRF52832?

Thanks

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.

If your STM Discovery board has a ST-LINK on-board, then it appears that you should be able to make it JLink compatible, see this page.

SEGGER offers a firmware upgrading the ST-LINK on-board on the Nucleo and Discovery Boards. This firmware makes the ST-LINK on-board compatible to J-Link OB, allowing users to take advantage of most J-Link features like the ultra fast flash download and debugging speed or the free-to-use GDBServer. SEGGER offers a firmware upgrading the ST-LINK on-board on the Nucleo and Discovery Boards.

Thanks. Could you use eclipse IDE for that? And can you turn an STM discovery board to a Jlink somehow?

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.
