K70 Tower System MQX Application in RAM

I'd like to find an example MQX application that executes from the K70 Tower System DDR memory.  So far, I haven't found any examples that seem to apply and the ones I've seen that locate things in external memory seem to be incomplete.  I've made changes to my linker configuration that look to me like they should work, but when I load the app to the target, the code runs into the weeds.  Realizing that MQX attempts to initialize DDR, I am aware that I may need to skip some of those steps.

 

BTW: I have a startup TCL script that configures DDR so my app can be loaded to it.  It's the "init_twr_ddr2.tcl" script that Freescale provides for bringing the K70 up with DDR configured.

 

Thanks in advance,

 

Todd
