Hello!

I use CCS 4.1.1.00014 and try to change  "Clock Configuration settings" for On-Chip Flash programmer but values doesn`t changed.  Please help me how I can change this settings.  Now I use menu:  TOOLS -> ON-chip Flash  -> Clock Configuration.  May be there is another menu to change settings?

Thanks.

    Are you trying to change the clock settings for a Piccolo (F2802x/F2803x) device? If so, it is intentional that CCS does not allow modification to the clock setting.

    Since Piccolo has an on-chip oscillator the plug-in can always use that source to program the device.  There is no reason to provide the ability to switch to an external clock source to program. If the user selects an external clock source prior to using the plug-in, the plug-in will switch to the internal clock.

    Thank you Aarti.

    Yes I use Piccolo F28027 device.  Now I understand that Flash Programer use 10MHz on-chip oscillator, but not external clock.
