Help with Boot Mode Configuration

I am having an issue with Boot mode configuration.   I tie Boot_mode_1 to ground and tie Boot_mode_0 to 3V via 4.9k resistor, and the IMX6 Dual/Quad processor still looks at port pins to set configuration - DDR memory configuration is set to the wrong state because I use a pull-up on EIM_A20.  I thought Boot_mode_1 had to be high for this to occur.

 

Also, if I ground both Boot_mode_0 and Boot_mode_1, my USB does not function even though EMMC has not received programming.

 

Any help would be much appreciated.
