I changed the order of RAM devices in the memory configuration so that the BOARD_SDRAM was right after flash because I was running out of SDRAM.  This somehow has caused my EVK to no longer work.  I'm not sure what I broke?

I tried following the document from this thread with no luck:  https://freescale.jiveon.com/message/1211245

I'm assuming it applies to SW8 on the RT1020EVK.  

Any help would be appreciated.

The only way I found to get the EVK out of this state was to use a JLINK programmer and use the GUI flash tool to put a .hex file from a known good project onto the micro.  It took a couple tries, but somehow it managed to snap out of it.
