  • [SOLVED]JLink Failed to erase sectors 0 @ address 0x00000000

    Hi,
    When I connect mk60n512 target board via JLinkGDBServer, the log says:
    ------------------
    ......

    ------------------
    I am not sure how to fix this issue, so could anybody help me?

    Thanks very much.

  • Hi,

    is it possible that the flash got write-protected by accident?
    If yes, please open the J-Link Commander and type
    unlock Kinetis
    in order to trigger a mass erase of the flash memory via the MDM-AP of the Kinetis device.
    Is the GDBServer then able to program the MK60N512?

    Which version of the GDBServer do you use (current one is V4.36k (release) / V4.39a (beta))?

    Best regards
    Alex

  • I was using JLink 4.28c and J-Link seems not working right, it did not prompt me a command line and just hanged.
    Don't know whether related to my cygwin or system environment.
    Anyway I switched Jlink 4.36i on another pc and unlock command ran successfully.

    Thank you for your quick support.
