nRFGo Studio Crashes

[Tim]

In the past nRFGo Studio worked fine. Then I reinstalled windows due to an unrelated problem (and changed from 32 bit to 64 bit), and now it reliable freezes.

Most often it works fine until you come to flash or erase a device - it can read the device fine but erasing it causes it to instantly freeze. Today however it freezes as soon as I select the "nRF51 Programming" device from the list. There's no error message; the UI just stops responding.

Anyone have any ideas?

Edit

Upgraded to 1.17.1 and now it crashes instead of freezing. Windbg gives this possibly not very helpful output:

Obviously I can't tell much more without the source code (or a debug build).

Update

Sorry - I had to reopen the question. I ended up ignoring this for ages but it still happens, even on the latest version (1.21.1). The older versions are no longer available to download so I can't even test them. :-(

We haven't seen this issue before.

Please try to uninstall both the Segger drivers and the nRFgo Studio, then run the nRFgo Studio install.

-nodefinitionupdate had little effect, although it does seem to freeze instead of crash now, and it doesn't get as far as displaying the flash for the device (previously it did and then immediately crashed). However, I did previously have problems with MCP crashing and disabling the JLink Driver "fixed" it, as described in your second link. Unfortunately if I disable the JLink Driver then nRFGo Studio doesn't list the device at all, so it isn't really a fix for this case. Any other ideas? I'm starting to suspect it is because of Websense, which is an annoying security tool work have installed on every computer. Trying to convince IT to temporarily disable it so I can check.
