nRF Connect, Ubuntu Gnome 17.04, blank window

Ladasky

Hello everyone,

I'm usually on the cutting edge with Ubuntu Linux. I upgrade my development box frequently, because I like the precompiled binaries in the Ubuntu repository. I prefer to use my time building nRF52 apps from source, rather than building Linux apps from source.

I just upgraded to Ubuntu Gnome 17.04. I also have nRF Connect v 1.1.1. I have a PCA10040 board connected to a USB port, to use as a BLE receiver.

I had everything working in 16.04, save for a mysterious, but apparently harmless, JavaScript error message which occurred when I closed nRF Connect (click here if you're interested).

On 17.04, nRF Connect starts up correctly. The Select serial port pull down menu shows my PCA10040 board attached to /dev/tty/ACM0. However, when I select that board, the whole nRF Connect window goes... blank.

Please advise, thanks.

    Hello again, Jørgen.

    I'm not sure what Google Chrome has to do with anything. I am already using Chromium version 58.0.3029.110.

    I upgraded JLink from V6.16, compiled 2017-06-02, to V6.16b, compiled 2017-06-09. V6.16b wasn't even released as of your last message.

    I need to ask a few questions before erasing the board.

    1. I have nrfjprog 8.3.0, it's about a year old. I suspect that I should update it. Where do I find it?

    2. The first time I ran nRF Connect on Ubuntu 16.04, I remember seeing a dialog box which reported a firmware upgrade. The details were not important to me at that time. But is it possible that I already have the current firmware?

    Thanks again for your continued assistance.
