DCSM - F28379D

Hello,

I'm somewhat new to the DCSM module, and am trying to get it to work for the F28379D.  I've reviewed most of the literature and examples, but still not having much luck.  Initially, I'd like to just activate a single zone (1), for all Flash and RAM.  I'm initially doing this under emulation, but will need to do for Flash boot as well.  I've seen two examples of trying to set the OTP, one assembly and one via #pragmas.  Preference would be the pragma approach, but I've gotten neither to work.  I'll start questions with the #pragma.  Below is what I've put in my main routine.  It was taken from one of the f2837x examples:

#pragma RETAIN( otp_data )

#pragma DATA_SECTION( otp_data, "dcsm_zsel_z1" );

const int32_t otp_data[ NUM_ZONE_SELECT_BLOCK ] =
{
0xFFFFFFFF,
0xFFFFFFFF,

),
0xF0F0F0F0,
0xF0F0F0F0,
0xF0F0F0F0,
0xF0F0F0F0 };

#endif

I've left the default 0xffffffff for EXEONLYRAM and EXEONLYSELECT, and changed the GRABRAM and GRABSECT to include all as secure (modified to use the defines the hw_dcsm.h file provided in the examples).  But when I load in the code, via emulator download, I see no change in these DCSM_Z1_REGS values, when looking in the registers window in CCS.  What should I be expecting?

For reference, here is my DCSM .cmd, also obtained from examples:

MEMORY

DCSM_OTP_Z1_LINKPOINTER : origin = 0x78000, length = 0x00000C

}

This is added into the project, in addition to 2837xD_FLASH_lnk_cpu1.cmd.

Please advise,
