[Newbie] IAR, TWR-K60N512 and couldn't program the flash memory

[pozz]

I tried everything without success.

I can correcly compile example projects from Freescale (KINETIS_SC.zip) in IAR Workbench 6.30. I can compile RAM and FLASH projects and I can debug from inside IAR using P&E Micro OSJTAG embedded in TWR-K60N512.

After that, I tried to save the program to the flash memory, so the application run automatically after switching on, but without success. I compile a FLASH project (such as hello_workd_k60_tower - FLASH_512KB_PFLASH) and I put it in run with "Download and Debug". It works. Now I close IAR IDE, press the RESET button on the board, but the application seems don't start.

I also tried with Project->Download->Download active application without success.

This is the output log during programming:

I searched for a solution on the web and in this forum, but I haven't found any.

I found an explanation, I don't know it is correct.

I compiled a project (that blinks a LED on TWR-K60N512) with Flash configuration and clicked on Download and Debug button in IAR environment. The LED starts blinking.

Now if I stop the debug from IAR, the LED stops blinking. I think IAR sets the OSBDM/OSJTAG (embedded on TWR) to keep stopped the main processor. The strange thing is that the program doesn't start even if I press the RESET button on the TWR board.

The only thing to do to see the program running, is to unplug and re-plug the USB cable. I imagine in such way, the OSBDM/OSJTAG re-starts in a normal mode where the main processor isn't keeped stopped.

Do you know if there is the possibility to unlock the OSBDM/OSJTAG from inside IAR, without disconnecting USB cable?
