Help with downloading new firmware on MIMXRT1064-EVK dev board

[clovett]

I have been using MCUXpresso IDE for the last few weeks with no problem to flash various SDK samples onto my MIMXRT1064-EVK dev board and everything is working great until today, suddenly MCUXpresso  is not finding my device, even though it shows up in Windows Device Manager as port COM7.  

So I looked at the instructions here and downloaded the MCUBootUtility and it is finding the board and while it says it successfully sent the "reset" command the memory is not showing up, and when I reconnect to the device or try and read any memory using the "Boot Device Memory" tab I get this error.  Is my devkit dead or what?

Executing: C:\nxp\NXP-MCUBootUtility-master\NXP-MCUBootUtility-master\tools\blhost2_3\win\blhost -t 2048000 -u 0x15A2,0x0073 -j -- flash-erase-region 1610612736 1024 9

}
}

Here's the full log from the MCU Boot Utility:

Never mind I figured out how to reset the first page of the flash memory starting at 0x70000000, so the device is discoverable again by MCUXpresso and I'm back in business...
