J-Link crashes when reconfiguring FlexRAM on RT1050

I am trying to perform a software reconfiguration of FlexRAM on the IMXRT1052, using just the SDK example, after the FlexRAM is reconfigured, the J-Link debugger halts with a HardFault.  I assume the J-Link is using RAM for execution and loses this when the RAM is reconfigured.


Is there a way to allow the J-Link to continue after the RAM is reconfigured?
