M52259DEMOKIT Does not run standalone, needs debugger to start running

carloscuevas — Sat, 05 Sep 2009 21:21:47 GMT

Hello, I 'm looking forward to use this very nice and cheap DemoKit in a school proyect, but theres something that realy annoys me: I flash the app and run it very nice, I can debug and even I can press reset and close the debugger, the app still runs. But in a power switching (power off and then on) it stops running and I need to run the debugger again and click on "run" to make the app run again. Is there any way to solve this problem? I will really need this board to run standalone. Any help would be very appreciated.

Are you sure that you have really flashed the application?

1) Check that the project's target is set for a FLASH version and not RAM version.

2) Ensure that you have used the FLASH tool to program the generated ELF or SREC.

See the following Kirin3 tutorial for step-by-step guide (see chapter 5):

Thankls a lot for your fast response, but I have found the problem. It seems that using the default firmware on the USBDM was the problem, I upgraded to the new USBDM firmware and also upgraded to CW for CF patch 7.1.2 and the problem is now resolved. I think it was the USBDM that did not let the chip run with the original firmware. Thanks to all.
