Getting Started with FRDM-K64F

To use FRDM-K64F with the latest MCUXpresso IDE, you need to update the firmware for its debugger. It is similar to FRDM-K82F where the details can be seen at the following post.

There are only a few minor difference between FRDM-K64F and FRDM-K82F to get started. Therefore, I will only list some major points here.

Figure. FRDM-K64F board

Original OpenSDA appears as MBED drive. And it is not working with MCUXpresso. To update the firmware for its debugger,

• Disable 'Windows storage services' ( https://os.mbed.com/blog/entry/DAPLink-bootloader-update/)
• Hold reset button and connect the device to a USB port. It should now appear as a drive called BOOTLOADER
• Drag and drop bootloader ‘0244_k20dx_bootloader_update_0x5000.bin’ into the drive.
• Remove and reconnect without holding reset. Board shows as ‘MAINTANCE’.
• Drag and drop Segger jLink OpenSDA for board specific firmware for K64F (‘02_OpenSDA_FRDM-K64F.bin’) which is available at https://www.segger.com/downloads/jlink#JLinkOpenSDABoardSpecificFirmwares
• Remove and reconnect without holding reset button. It now appears as ‘FRDM-K64FJ’
• To use JLink , open cmd and enter
  
  

  > cd "C:\Program Files (x86)\SEGGER\JLink"
  > JLink.exe -speed auto -device 'MK64FN1M0xxx12' -if SWD
  

  
  
  
• At the JLink prompt
  
  

  J-Link> r
  J-Link> erase
  J-Link> q
  

  
  
  
• After that, it should be OK to use MCUXpresso
