How to load the program in the K40 uC

abulhasan — Mon, 01 Apr 2013 14:24:47 GMT

We have developed the code using Code Warrior and did the debugging using the given USB cable. It works when the USB cable is plugged in from the PC. . But after removing the USB cable from the PC and if we give the external power supply to Kwikstik K40 board it does't work. Pls let me know as soon as possible.

Thankyou.

Are you using Flash or Ram?

If the program is properly configured for FLASH, the program has been programmed into the FLASH after debugging. You can check the FLASH memory in debug windows to see if it is properly programmed.

Hello Abul hasan,

I faced once similar problem, application was running using debugger, once power was reconnected, no action. I found out it was a matter of a clock initialization. I would suggest you to at least use any indicator (LED, console, etc) to find out how far your application gets and where it gets trapped. This applies if your programmer is really functional and program resides in FLASH.
