nRF Connect Programmer hangs on start

[Jackson Wilson]

Configuration:

• nRF Connect for Desktop v3.7.0
• Programmer v1.4.11
• PCA10040 v2.0.0 EVK (date code 2020.39)
• When Programmer app does start Log says: "Using nrfjprog library 10.12.1, pc-nrfjprog-js 1.7.6". 
• OS: Windows 10.

I can program debug with this EVK using SES.

When I start the Programmer app with the EVK plugged in, Programmer app hangs with blank screen.

I have tried upgrading/downloading EVK J-Link to v6.92 and 6.44e.  With 6.44e, sometimes Programmer will start, then hang when I attempt to select this J-Link.

CTRL+R while Programmer is stuck will re-start it (spinning wheel), then it goes blank again. 

I can get no log output to debug the issue from Programmer, since it just hangs with blank screen.

Any suggestions?

Hi,

Could you try updating to jlink v6.88a?

Still fails with v6.88a or v7.50a.   Yesterday it worked for a while with v7.50a, now it hangs with either driver.

Pressing CTRL+R repeatedly eventually gets Programmer screen to come up, but selecting EVK causes blank screen/hang again. 

Very erratic behavior -- occasionally Programmer can recognize EVK and function, but it usually takes multiple CTRL+R to get this to happen.  This seems to be the case with J-Link v6.88a and v7.50a.

Once EVK is recognized, Programmer seems to work correctly.

Ok, We've started an internal investigation into this issue. I'll update you when we have more information.

Please expect some delay as many of us are out of office due to the summer vacation.
