bfrom_SysControl Return Code 201 (error setting PLLDIV)

I'm trying to debug a problem setting the PLL divider ratio using bfrom_SysControl on a BF548.


When I try to set the PLLDIV using this line:

rc = bfrom_SysControl(SYSCTRL_PLLDIV | SYSCTRL_WRITE, &frequency, NULL);


It will return 201 (decimal) when running via JTAG, unless I set a breakpoint in the function that calls bfrom_SysControl (in that case, it succeeds).  It also seems to work (returns 0) when running the executable from NOR flash without a JTAG pod attached.


To start, I'm very curious about the meaning of the return code.  I can't seem to find a reference for this anywhere.  Any ideas?
