Bootloader reprogramming on FRDM-KL25Z board

Hello all.

     I recently had problems getting my Windows XP to recognise the board. Problem fixed - bad USB cable.

 

     However, during my fevered attempts to get things working, I postulated that the bootloader program was corrupted.

I tried to locate a binary image of the bootloader so that I could use a JTAG compatible interface to replace the (supposedly) corrupted binary but was unable to locate such an image.

 

Is such an image available on the net?  Which particular version of the JTAG spec. characterises the interface which programs that image onto the board at the factory.

 

You realise that shipping a $10 item back to the factory for bootloader reprogramming would be the height of stupidity?

 

Peter
