  • [ABANDONED] Failed to update bootloader

    I am trying to update bootloader on my FRDM-K66F which is in a brick state right now.
    On erase JLink returns error (-1). Loadbin command shows success however the board remains in dead state.

    Thank you,
    Igor

  • Hi Igor,
    Thank you for your inquiry.

    Could you please answer the following questions?
    1) How exactly did you "brick" the board?
    2) Does erasing work if you reset the device first?

    Source Code

    1. r
    2. erase
    3) Can you confirm if the data is indeed the correct data after flashing the device?
    4) Does the loadbin command work with a different data file?

    5) Could you please send us a J-Link log file? How to enable:

    Best regards,
