TMS320F28379D: can't get launchXL to boot from flash

I have a CCS10 project working fine with ram JTAG build on launchxl-f28479d. I have not been able to get it to boot from flash.

I created the flash configuration. It modifies the project: full optimization, add _FLASH define, remove DEBUG define, linker includes entry point=code_start and initiialiation model =line using ROM

When I enter debug mode, the flash is erased and seems to load correctly. I power the board off, set jumpers 1,2,3=on,on,off, remove jtag connection. Power on and no led flash=not running.

If I connect with jtag, and run in FLASH mode, it works fine.

My linker file is below. Am I missing another step? 

thanks
