J-Link: "The firmware of the connected J-Link does not support the following memory access: Read @ 0x02000004

[awneil]

I am starting afresh, and have only just downloaded & installed Keil v5.25, nRF SDK v15.0.0, and nRFgo Studio v1.21.2.10

So everything should be "latest" and "up-to-date"

I have successfully built the PCA10040  'blinky' example (0 errors; 0 warnings), but the download fails:

I have not modified the project - it's straight from the SDK download.

As advised in "Compiling and running a first example", I erased the board first.

This seems to be a recurring problem:

https://devzone.nordicsemi.com/f/nordic-q-a/33412/error-when-loading-program

The "solutions" stated there all seem to be to "update to the latest" - but I should already be at "latest".

Nobody seems to have got to the root of why the J-Link is trying to do that, and/or why it is failing.

The PCA10040 board sticker says v0.9.0

I am running on Win7-Pro 64-bit

This is what appears in the uVision 'Output' windows when trying to do the download:

Ha!

How Naive!

The nRF Command-line Tools installer has installed a really old Segger JLink software!

In fact, we can see that it's waaaay older than anything I have before:

If I restore the the version which Keil had before - v6.30h - it works fine (after doing a JLink FW update):

Are you using an old command-line-tools installer?

Download the newest here, it comes bundled with Jlink v6.20i:

https://www.nordicsemi.com/eng/nordic/Products/nRF51822/nRF5x-Command-Line-Tools-Win32/33444

Side note: your pca10040 0.9.0 uses engineering B nRF52832 IC... so you might want to upgrade 

[awneil]

Like I said - I just downloaded the latest of everything from the Nordic site!

The command-line tools were installed automatically when I ran the nRFgo Studio installer:

So why would that be pulling-in an old version?

How do I check the version of command-line tools?

Yes, the DK is old - new hardware is on its way ...

[awneil]

C:\Users\xxx>nrfjprog  -v
nrfjprog version: 8.5.0
JLinkARM.dll version: 6.14h

nrfgo studio is kinda deprecated, 2 years since it was updated or something, so that's the reason it's pulling an old version. nRF connect for desktop is the cool kid now: www.nordicsemi.com/.../nRF-Connect-for-desktop
