OpenOCD seems to not work with Segger JLink Firmware latest version (4.50i). If FW is switched to 4.10i, things seem to move along. Is this a known issue ? Here is what I see in openocd output

Any workarounds or fixes for this ?

Hi Bob,

I did a quick [search of the developers mailing list and didn’t see anything. I’d say post there if your search also comes up empty.](Best Open Source Mac Software 2024)

OpenOCD is now trying to maintain a list of known working versions.

At the moment only versions marked “Jan 31 2011” are not working as expected.

However I have not updated my jlink for a while and am happily using the following version:

May 3 2012 18:36:22 - comes with package v4.46f

The link to the jlink driver src is here, search for unsupported_versions
