MCUXpresso Failing to discover CMISIS-DAP probe on Eval Boards, Redlink Server not opening

Hi,

I'm having problems getting MCUXpresso 11.0 to discover the probes on 2 eval boards (MIMXRT 1064-EVK and MIMXRT 1050-EVK). I am using Windows 10

 

When I launch the debugger, the IDE gets stuck on "Probe discovering for MCUXpresso IDE Linkserver (inc. CMISIS-DAP) Probes" until it times out then I get the following error:

 

RedlinkServerException

Reason:

Cannot write to server: not open

I've tried:

-with the J42 jumper connected on the RT 1064 EVK (uses LPC link probe instead of cmisis-dap)

-disabling windows firewall

 

Any help would be awesome, thanks!
