FRDM-K20D50M uTasker USB Bootloader application program

Question asked by jerry favero on Nov 6, 2014

Good afternoon,

I'm testing the FRDM-K20D50M board. I flash it with USB Bootloader uTaskerSerialLoader_FRDM-K20D50M.S19.

I made a little code for blinking a led with Processor Expert:

//................................................

while(1)

{

    LEDRED_ClrVal(NULL);

    WAIT1_Waitms(250);

    LEDRED_SetVal(NULL);

    WAIT1_Waitms(250);   

}

//................................................

The README file says :

"If you load your own application make sure that it has its reset code is linked to be at 0x8080. Interrupt vectors should be run from RAM or set to a

location in the code (not left at 0x00000000)" .

I have set the CPU component as in figure :

After the drag and drop of a program file the board does nothing, the led don't blink.

The Output File Format is ".SREC" .

A normal program with "Default memory for Interrupts"=INTERNAL FLASH, and address=0x00000000 works fine with blinking led.

There is something wrong. I attached the project.

Thanks to whoever can help me.

Jerry
