OpenSDA firmware for FRDM and TWR boards

  • Hello,

    I'd like to ask several questions regarding usage of the OpenSDA firmware for FRDM-K64F (OpenSDAv2) and TWR-K65F180M (OpenSDAv2.1 I suppose) boards. Both boards have MBED bootloader. I downloaded firmware package but I'm not really sure which app I can use. I'm rather cautious because I don't want to brick my devkits.

    1. FRDM-K64F

    There are following apps:


    Can you describe the difference between these images? Can I use them all with MBED bootloader? If not, can the booloader be safely changed to PE OpenSDA bootloader (BOOTUPDATEAPP_Pemicro_v111.SDA)?

    2. TWR-K65F180M


    The questions are essentialy the same as in the case of FRDM-K64F.

    3. There is image named MSD-DEBUG-TWR-PWR_Pemicro_v118.SDA. What is it good for?

    Thank you.

    Best regards,


    • Please, can someone respond to me?

      Well, maybe I asked too many questions at once. OK, please tell me one thing:

      How does one use 'MSD-DEBUG-FRDM-K64F_Pemicro_v114.SDA'?

      Bootloader refuses to accept it as there is not enough space on the 'BOOTLOADER' virtual drive.

      Thank you.

  • I got a similar error when I was following a set of instructions that did not truly apply to the TWR board being used. Then the board was stuck in bootloader mode (slowly blinking LED near USB).

    Thankfully, NXP keeps the firmware versions of OpenSDA for each board at the following url:

    If you encountered the same issue, select your board from the dropdown list in the above url.

    I downloaded the binary for CMSIS-DAP, there. Then pasted the *.bin file into the BOOTLOADER drive. This recovered the debug unit/board.

  • Hi Martin, 

    FRDM-K64 board comes pre-programmed with CMSIS-DAP MBED OpenSDA firmware. Hence, you should use DEBUG-FRDM-K64F_Pemicro_v108a_for_OpenSDA_v2.0.bin OpenSDA firmware on this board to make it act like a PEMicro interface for run control debugging and FLASH programming.

    This firmware supports Debug and CDC serial port functionality, but does not include drag and drop MSD mass storage device support.

    TWR-K65F180M board comes pre-programmed with a full PEmicro OpenSDA stack, hence i recommend using the MSD-DEBUG-TWR-K65F180_Pemicro_v118.SDA, which supports Debug, MSD and CDC serial feature set.

    Best Regards,
