I got some more insight into this. I will try to convey what the developer told me.

The whitescreen is most likely related to jlink, since Toolchain Manager does not have that problem which doesn't use device selector menu.

To downgrade jlink requires change in the registry, and it does not seem like you did that, but when you upgrade it, this is not necessary. What version of jlink are you using? The newest one? Make sure you install the newest one, or the one that comes with the nRF Connect for Desktop app.

To use an older version of nRF Connect for Desktop is not that easy, since you will get the last version of all the apps, which are not compatible.

Some other causes to this may be:

If you have a unicode-character in the user path
If some of the usb-devices connected gets device-listing to crash. It may be a usb hub or some other device

Also could you provide me the "system report" from nRF Connect for Desktop?

Best regards,

Simon

I'll forward your feedback to the developer, and get back to you when if I get any insight on the problem.

Hi Simon,

I have for the second time uninstall nrfconnect 3.6 for desktop, jlink drivers and install again this version but I obtain the same result a white screen !

I have also try to uninstall the 3.6.0 version, Jlink drivers and install the nrfconnect 3.2.0 version ( the one I had before moving the PC and It's always white screen.

In the mean time I've install nrfconnect 3.6 for desktop and the jlink driver on an other PC and it work, so for now I can work.

But I already need to work from my own pc, so what can be the problem?

Best regards

I talked to one of the developers and got a suggestion: "try to uninstall nrfconnect for desktop, jlink drivers and install the latest 3.6.0 again"

Best regards,

I will talk to some of the developers of the nRF Connect for Desktop app tomorrow and ask what may be the reason for the white screen.

Hi Simon,

Is it also possible to downgrade the nRF Connect 3.6.0 to 3.2.0 ?

I don't understand why I had using the nRF Connect software at the beginning of september without problem and now, after moving the pc, it refuse to work ?

Hope you have a solution.

[quote user="Jiemde"]So you say that the solution is to use the "Getting Started Assistant" ?[/quote]

No, you should not use the "Getting Started Assistant" since it's deprecated. Use instead the Toolchain Manager (recommended) or install it manually.

I have about 300 units of nRF52832 to flash but I cannot !!

Is it possible to have support for resolving that ?

[/quote]

I would really like to get to the bottom of this. In this ticket, it seems like the customer was able to resolve this by downgrading to JLink 6.54c, could you try the same?

Regarding flashing the units. This can be achieved by installing the nRF Command Line Tools and using the nrfjprog executable (nrfjprog --program <name>.hex --sectorerase). You will find the hex file in <application>/build/zephyr/merged.hex (if multiple/child images) or <application>/build/zephyr/zephyr.hex (if single image)

Hi Simon, It's because I just try what I use before.

To be more precise I use "Power Profiler" and "Programer" and they screen are white.

So you say that the solution is to use the "Getting Started Assistant" ?

Is there a tutorial for that?

Best regards

The reason you see "DEPRECATED" in the "Getting Started Assistant" app, is because it is deprecated for Windows. The inteded way of installing the nRF Connect SDK is through the Toolchain Manager (recommended) or Manually

Earlier you sait " the nRF connect application is not running and show a white screen for all applications except for Toolchain Manager*

Which means the "Getting Started Assistant" app showed a white screen.

But now you said you see "DEPRECATED", which means that your issue regarding the white screens has been resolved? Am I right in my assumption?

Simon

Hello Simon, thanks for your fast reply

My OS is Windows 10

Updating SEGGER J-LINK Software don't resolve the problem after rebooting the PC screen still be white.

Updating the nRF Connect software to the new version 3.6.0, restarting the PC and screen still be white !

Hope you have other solution ?

What OS are you using?

Could you try this:

Press CTRL+R and see if the white screen goes away.
Install/update the SEGGER J-Link Software

Best regards,

Simon
