Hello sandeep

Thanks a lot for contacting us.

To create a new project in CodeWarrior v10.6, user just need to click on <File> menu->New->Bareboard project, and choose your MCU type, language, emulator etc.  CodeWarrior will generate a template, including the necessary target settings, startup files, vector table, linker command file and libraries.

I attached the example project for the 1st green led blinking on the TWR-56F8400 board. I created this project from <File> menu->New->56F84789 project, and enabled Processor Expert.

Then added the LED component and TimerInt component into the project, and in the timer ISR function named TI1_OnInterrupt(), calls the LED function LED1_Toggle() to blinking the led.

In addition, please disable the watchdog in CPU component. By default, it is enabled.

We also have example projects for MC56F84789 under CodeWarrior folder:

C:\Freescale\CW MCU v10.6\MCU\CodeWarrior_Examples\Processor_Expert\DSC\TWR-56F8400

These projects are developed with Processor Experts.

The help documents are also delivered together with CodeWarrior, user can find them under:

C:\Freescale\CW MCU v10.6\MCU\Help

Hope it helps!

Best Regards

Hi, Fiona,

I'm using a MC56F8365 chip. In your reply, there is nothing about bootloader. Is it because the board you are using is a special one ?

We are using a board designed by ourselves, do you think it is a must for us to have bootloader ? It will be great if there is a way to write into the board directly.

BR.
