[SOLVED] JLink.exe crashes when used with Sophos Endpoint Security

Hi All,

I've been having issues with JLink.exe crashing when Sophos Endpoint Security (anti-virus software) is active.

I have a crash dump file, but it's too large to attach (3.4MB). Is there anyone I can send this to?
I did attach a .zip file with the Metadata and version info.
It appears there's an access violation or unhandled exception in swi_ifslsp.dll from Sophos.
Our company is using about 20 of the J-Link probes for engineering and production use.

It turns out there's an interesting workaround: if you run one instance of JLink.exe and let it sit in the background, other instances won't crash.

I loaded the memory dump file into Visual Studio 2012, but the debugger doesn't have access to the JLink.exe internals.

Thanks for any thoughts you might have or who I can share the crash dump file with.

Thanks,

Hi All,

Just a quick update. I was able to do some more experimentation with Sophos anti-virus. When I set "Block access to malicious websites" to Off and reboot the computer, JLink.exe runs fine without any problems.

I tried JLink 5.10h that was released today and it fixes the issue!

Many thanks to the Segger development team for fixing this in a timely manner. This can be marked as [SOLVED]
