  • [SOLVED]Flasher STM8 not work on STM8S103K3

    Hello

    I want to use Flasher STM8 as a standalone programer for STM8S103K3 but there have a problem that when I select

    Unsecure chip, the error message show
    - ERROR: Failed to unlock chip (MASS unlocking failed)
    - ERROR: Failed to unsecure chip (removing read out protection failed)
    - ERROR: Failed to unsecure chip

    Erase chip, the error message show
    - ERROR: Failed to check sector status for sector erase
    - ERROR: Failed to erase chip

    Program, the error message show
    - ERROR: Failed to unlock chip (MASS unlocking failed)
    - ERROR: Programming failed @ addr 0x000000
    - ERROR: Failed to program target


    I try on STM8S105K4 and STM8S208MB.
    The STM8S105K4 have a same problem but on STM8S208MB every thing is OK and standalone mode is work too.

    What should I do?

    Hello,

    We have tried to reproduce the problems you are reporting using a STM8S103K3.
    To be able to give this case a deeper investigation we would need to get some more information about your current status:

    - Do you use the latest SEGGER software for Flasher STM8 that is available (V1.06b at this moment) ?
    - When using the STM8 Commander, does it report that a target chip has been found "Found STM8 (xMHz)" ?
    - Are you able to read memory using the STM8 Commander by using the command "mem" ?

    - Is your program linked to addr. 0x000000 ?
    - Can you add a Flasher STM8 project to your reply so we will be able to reproduce this problem the very same settings that you do ? This may contain dummy data files but helps to reproduce a reported problem as well.

    I try both V1.05 and V1.06b, the result is not defferent.

    Q: When using the STM8 Commander, does it report that a target chip has been found "Found STM8 (xMHz)" ?
    A: I think this is a problem, when connect to STM8S103K3, STM8 Commander don't have "Found STM8" message.
    While connect to STM8S208MB, STM8 Commander show "Found STM8 (8MHz)"

  • Hello, All

    I found my problem. On my STM8S103 board, the Capacitor at NRST pin is 2.2uF ( Recommend by ST Field Application Engineer ) which is work with ST-LINK.
    Now, when I replace it with 100nF, evevy thing is OK.

    Thank you All

  • Thank you for the update.
    Glad to hear that you found out the problem. Might help others here as well.
