I did not see a similar post on this in the forum so here we go-

I was working thru the "Freescale Kinetis lab.pdf" Using TWR-K60N512 and flashing/debugging thru PE MICRO OSJTAG.

Using Keil 4.5.0 I ran the c:\keil\Boards\Freescale\Blinky program. It downloads and runs fine. However, during debugging realtime updating of certain variables (ie 'num' variable, defined statically defined from the symbol window with View/Periodic Window Update checked) does not really update real time.

Does anyone know the cause of this discrepancy? I was suspecting OSJTAG is not capable of realtime updating? I have a Segger J-link in hand and a 100mil->50mil cortex debug adapter on order so perhaps that will take care of this?
