Does SEGGER JLink version affect BLE programming?

Ladasky

Yesterday, I asked a question (so far, no one has answered) about how an OS upgrade on my desktop computer might have broken my ability to flash and run BLE apps on the nRF52 Preview DK, PCA10036.

devzone.nordicsemi.com/.../

I had questions about the version of SEGGER JLink I was using before (which I did not write down) versus the SEGGER JLink I currently have installed (version 6.0.6). Today I came across this post:

devzone.nordicsemi.com/.../

...which implies that Nordic included SEGGER 5.10 in a Win32 command-line support package intended for PCA10036 development. I work in Linux, but I am still noting the difference in versions.

I know that JLink is not Nordic's software, but are there known differences between the various JLink versions? If there are problems, should this information be added to the Compatibility Matrix page (infocenter.nordicsemi.com/index.jsp

Thanks for any advice.

    No it doesn't matter at all as long as your JLink version is recent enough to support the chip you're using (eg very old JLinks didn't support the nRF52), so anything newer is fine, modulus the occasional bug which gets added. So 6.0 is fine and nothing needs to go into any compatability matrix.

    Adding one note that if you're using something compiled against the JLink SDK there can be issues however again for the most part even that is very forward compatible.

    Try JLink from the command line to figure out whether it's the python tools which don't work or if your basic JLink package doesn't work.

    That's right RK, the compatibility matrix says that the only version of the S132 SoftDevice which is compatible with the Engineering A (PCA10036) boards is 1.0.0-3.alpha.

    Now that we have a year's worth of experience with the alpha version of the nRF52 and our project is growing, we will be getting some newer boards. But I had to hand one of the original boards off to another team member for Bluetooth work, and I needed to give him a board that was actually doing something over BLE.
