PGA900EVM: PGA900 does not run remapped DEVRAM after hex file download

Part Number: PGA900EVM


I have followed your procedure as shown below but can not get a simple application that sets the GPIO1 output high.  I am doing this because I want some indication that the remapped software does actually execute.  We are having a very difficult time using the PGA900EVM and GUI.  Nothing seems to work.  Is there something I am missing?


To program in DEVRAM, make sure to put the microcontroller into reset by pressing the the button on the top left corner of the GUI. (Or you can write a 0x03 to the MICRO_INTERFACE_CONTROL register in the low level page). 
Then you can program the device using the DEVRAM programming instructions as you had followed in the User's Guide. 
After that, Press the button that says "REMAP Disabled" on the programming page to enable REMAP. This maps the DEVRAM in the correct location for operation with the M0. 
From there, you need the memory loaded into the microcontroller, so take it out of reset by pressing the button on the top left again. This should let you see the GPIOs pull high.
