JLinkGDBServer not connecting to MIMXRT1050-EVK

I am a Ubuntu 16.04 development host and installed the Segger tools. I have connect the eval board port J28 and the mass storage device appears. I can load up designer loads by dragging and dropping. All settings on the board are default and it is using HyperFlash. When I try to start the JLinkGDBServer it does not see the target. What steps am I missing?
