Hello I am using MCUXpresso IDE, version v10.1.0 [Build 589] [2017-11-14] with an MIMXRT1050-EVK SDK, version  2.3.0 (2017-11-16).   I was previously using a Rev. A3 of the MIMXRT1050-EVK and was able to program and debug via the OpenSDA interface under both Linux and OSX.  Our new A4 boards do not enumerate under Linux and although they enumerate under OSX, they can not be debugged under OSX.  When a debug is attempted the following error occurs:

I have tried changing the DAPLink firmware as I had to do on the A3 revisions but this did not fix the issue.


Any insight into this issue would be appreciated, thanks.
