FRDM-KL25Z uTasker USB Bootloader application program

Question asked by jerry favero on Nov 25, 2014

I'm testing the FRDM-KL25Z board. I flash it with USB Bootloader uTaskerSerialLoader_FRDM-KL25Z.srec (download from utTasker site) .

Similarly as FRDM-K20D50M FRDM-K20D50M uTasker USB Bootloader application program

in an application program :

1) I have disabled "Generate Linker file" in Build Option in PE, and edit it manually as :


  m_interrupts      (RX):  ORIGIN = 0x00008080, LENGTH   = 0x000000F8

  m_cfmprotrom  (RX) :  ORIGIN = 0x00008400, LENGTH   = 0x00000010

  m_text              (RX) :  ORIGIN = 0x00008410, LENGTH   = 0x00017BF0

  m_data            (RW):  ORIGIN = 0x1FFFF000, LENGTH  = 0x00004000


2) In "User code after PE Initializzation" in Build Option I have added , that is visible after building in CPU.c file:



  uint32_t *pdst ;

  uint32_t *psrc;

  uint16_t  i ;

  // Copy Application Stored Interrupt Vector table to RAM

  pdst=(uint32_t*) (0x1FFFF000 );

  psrc=(uint32_t*)( 0x8080 );

  for (i=0;i<0xF8;i++,pdst++,psrc++)

  {        (*pdst) = (*psrc);


  // Then redirect the vector table to RAM by changing the SCB_VTOR like this:

  // Redirect the vector table to the new copy in RAM

  SCB_VTOR = (uint32_t)(0x1FFFF000);



I made a little code for blinking a led with Processor Expert, but


unfortunately the led don't blink.There 's something wrong.

Thanks to whoever can help me.
