Can an STLINK be used with nRFgo Studio?

Thanks RK. OpenOCD looks to be a tool I should get familiar with. Just not at this point as mastering a debugger is not my goal at the moment!

2 answers to that, yes and no. OpenOCD offers compatibility with more programmers and thus more target devices. Segger offers compatibility with a large range of ARM devices. So you'd say there that OpenOCD is 'better'. However OpenOCD's breadth of coverage gives it a steeper learning curve and it requires a bit more tuning to get it to go with some chips. Also support relies on 3rd parties adding it and it's not always correct or fast, and for proprietary emulators, non-existant. Only recently is STLINKv2 supported, after being reverse engineered.

I like JLink because it's supported, natively, by the IDEs I use, it's multi-platform and I know if the boards I'm using is listed and I plug the JLink into it, it's going to work, and if it's not supported, but is ARM, it soon will be and I don't have to mess with it.

if you 'get good' at OpenOCD you probably find it just as easy.

Thanks for the vote of confidence on the edu verson RK. Yes, I am a hobbyist for the time being. Just a quick question: does Segger J-LInk offer more capability than say, OpenOCD or other cheap SWD supported programmers?

It is - and it's very good too - works down to minimum voltages. And despite the name 'Edu' it's actually available for anyone for non-commercial work, it's really JLinkEdu or Hobby.

Is there a list of supported/tested programmers? JLink is expensive ($1000). STLink would be nice if it works as it's proliferate.

/update Nevermind, I realized there is the edu version of the J-Link. $60 USD is very cheap.

OpenOCD 0.9 works well with the nRF51422 part.

I use the following commands in a telnet session:

reset halt

nrf51 mass erase

program s110_softdevice.hex verify

program myApp.hex verify reset

It works for me.

We haven't tested STlink with studio and it probably would not work. We have been working with Segger J-link. There might be other way to use STlink with our nRF51422, but we do not have any support for it available.

How about something like this one. It can flash softdevice + app + DFU without requiring mergehex. It costs about $45 but it's a stand alone CMSIS-DAP jtag, not linked to a dev board. embeddedsoftdev.blogspot.ca/.../idap-link.html Multiple boards can be used to flash in parallel for gang programming using the IDAPnRFProg on Windows or OS X.
