NRF Connect Programmer Failure

[KentOverton]

I've been developing in the following environment:

Windows 10

 NRF Connect for Desktop

      with few problems for the past six months.

On Friday 12/10 I was suddenly unable to debug my application - Toolchain V 1.7.0 /Seggar - would not download new code to my board.

After a little investigation I discovered that Programmer (accessed via NRF Connect for Desktop) did not recognize my custom board, nor would it recognize any of three NRF Development Kits. I have two PCA10095 and a very old PCA10001.

I uninstalled NRF Connect, NRF Command Line Tools and Segger JLink and re-installed and see the same results.

The log file from Programmer is

Hi Martin,

How many boards do you have connected to the PC? Do you face the same issue when connecting 1 board and multiple boards? Could you tell me you JLink version? I would suggest you to try using the nRF Connect for Desktop 3.7 and check whether you still face these issues.

For downgrading to v3.7.0, you could open the nRF Connect for Desktop, go to the Settings menu on the top left and select the "Add Source" option and enter this link: https://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json 

Kind Regards,

Priyanka

Hi Martin,

How many boards do you have connected to the PC?      One.

Do you face the same issue when connecting 1 board and multiple boards? I've never connected multiple boards.

Could you tell me you JLink version?  V6.88a

I would suggest you to try using the nRF Connect for Desktop 3.7 and check whether you still face these issues.

I tried that. After applying the change in 'Settings" I see a note saying "3& Compatible Apps'.  When I run 'Programmer' it runs Programmer V2.0.1, which shows the same failure.

Hi Martin,

Could you try upgrading the JLink to v7.20 or even to v7.58b?

Regards,

Priyanka

[KentOverton]

I'd be happy to. How do I do it?

[KentOverton]

Neither 7.20mor 7.58b make any difference.

I see the following four lines in the Programmer log

2021-12-14T16:32:00.158Z DEBUG iface: Ethernet
2021-12-14T16:32:00.158Z DEBUG IP4:

Doe this have any bearing on the problem?
