How can I get nRFgo studio to recognize my Development kit again?

[Michael]

I used to be able to see my development kit in nRFgo studio and flashed S110 onto the chip. Now all I see is: "No boards connected". I am still able to flash programs onto the chip with Keil, as long as they are designed for S110, so my computer can still access the device. If there is a driver I'm missing, it's not showing up under the Device Manager. I'm not sure what caused this.

I've already re-installed all of my programs and updated all of the current drivers under nRF DK.

I'm also having the same issue with regards to my dongle and the MCP. It used to be able to detect the dongle, but now it just says "No Master Emulator Connected".

Any help would be very appreciated.

@Michael: It's pretty strange the issue you are having. Have you tried to connect it to another PC ? You may also want to try instal nRFGo Studio v1.19 for testing. To downdload different version of same program you can click on the version number.

If you couldn't make it to work with nRFGo Studio, the temporary solution is to use nrfjprog.exe tool. It's a command line tool and nRFGo Studio uses this tool to program, erase the chip.

I don't have another computer that would work right now, I just have this computer, my work computer, and an asus tablet that doesn't have the best performance/capability; but that's a good idea. I tried installing an older version, it errored, that might have been because I had a newer version of some other software or a newer driver.

I uninstalled all of the programs and drivers I've installed recently since this issue began, because something I installed messed the nRFgo studio up, re-downloaded all of the Nordic software and installed from scratch. I still have the same issue.

I don't want to erase the chip because I have S110 on currently, which I think is the Softdevice I wanted to use, still this problem is upsetting. Do you think I can use the cmd tool to figure out my issue? I just opened it up and am reading it now.

A tablet could be an issue. We haven't got much test with using nRFGo Studio with tablet.

You can use nrfjprog to program, verify , erase, pretty much anything that nRFGo Studio can do.

I finally figured out my issue after I stopped looking into it for awhile. After I had installed Nordic software I installed software that called for Segger v5.00. At the time of writing this nRFGo Studio is using Segger v4.98c. Windows registry for Segger was changed to v5.00 and I'm guessing nRFGo Studio kept looking at v4.98c (This is a paraphrase, I'm not an expert on the registry). Even after uninstalling all of the software that I had installed, the registry for JLink was kept at v5.00. After I went into the registry and changed Segger/JLink/InstallPath back to v4.98c my problem was solved.

I hope this helps someone who has the same problem as me. I found out about this registry problem by reading someone else's self fixed problem. I have an inquiry for more information, so if a Nordic employee sees this I'll post that inquiry as a comment.

The nrfjprog.exe tool looked interesting in the short time that I looked into it. Is there any literature for the tool other than the -help (I think) drop down descriptions?
