Concerto ARM-core: SYSCTL_MWRALLOW register read value?

Will Flanery
Intellectual 470 points


On the Concerto's ARM core, the value of the MWRALLOW register doesn't seem to change.

The first executable code in my main(), and in all the examples, is to "disable protection" with this command:
      HWREG(SYSCTL_MWRALLOW) =  0xA5A5A5A5;   // SYSCTL_MWRALLOW = 0x400FB980


I'm quite certain that, in the past, I have observed the change in the debugger register view at SYSCTL -> MWRALLOW
Currently, however, as I step through the code, it remains all zeros.

Thanks,

-Will
