Unable to work with Segger Embedded Studio anymore

[brianreinhold]

Not too long ago I was able to use Segger Embedded Studio with my nrf52840 DK, compile and build projects and run it. Unfortunately I have moved to a new computer and trying to redo this is proving to be a nightmare. Before two packages were downloaded, SES and Jlink. Now that does not seem to be the case. I download the latest SES, install the license, run open my project and it builds. Forget trying to connect and use the DK however. Jlink simple does not connect. How was something that was so simple now become so hard?

Documentation is hopeless. It may be out of date or wrong, I don't know what. Plugging in my DK to USE does get the LED to light up, but it does not blink. I see Jlink in the Windows file explorer. The SES config says USB and SWD. But when trying to do anything I get this dialog saying no Probe (never needed one before) use IP instead?

You have got to be kidding.

Selecting tags is horrible still/. Can't this ever be fixed? No tags for this issue anyways.

It seems that your PC is unable to connect to the debug probe on the DK. Try installing the SEGGER USB driver as described here:

The link led you to a very confusing set of documents. In the end you could have pointed out that you need to download J-Link Software and Documentation pack from here

https://www.segger.com/downloads/jlink/

And once installed there is a driver in the USBDriver directory of the installation. In that directory there is a program InstDrivers.exe. Run that and the installation is done and J-Link connects in Segger Embedded Studio. I had already downloaded that package yesterday in one of my many trials. I did not know there was a separate driver in it that needed to be independently installed. (I thought it WAS the driver). Looking on my laptop (that works) I saw the driver in the device manager. There was a different driver on my Windows 11 system.

The Jlink driver is installed together with Segger embedded studio, but it does not include the legacy usb drivers.

Interesting. I saw no J-link driver of any type in the device manager. It did show up as an external drive, however. THough I copied my hex file to the drive (as stated in one of your instruction manuals for getting started with nrf52 and the SDK). It copied something but the app was corrupted and did not run. Segger Embedded Studio refused to connect to J-link (I guess that's because the only thing there was to link to was my DK.)
