  • [SOLVED]pb flasher stm8

    with device STM8S207R6, when the sectors of the target are locked , I can't programming with the flasher in standalone mode.

    the option "automatically unlock sectors" is selected.

    I use the software v1.00h

    thank
  • Hello joubin,

    To be able to reproduce your problem we need some more information:

    - Are you trying to program option bytes ?
    - If you are trying to program option bytes which values do you try to program ? (most important the first 16 bytes)
    - Is the target secured by read out protection or does it use user boot code area ?
    - What option do you use for AUTO programming ? (can be found in menu "Options->Project settings..." in tab production)

    Regards,
    Oliver

  • HELLO

    I want reprogramming the same option byte AA 03 ... (with read out protection)

    the µc of the target have already the same option byte

    for AUTO programming I select the cases Programm and Verify



    when I program the target , I have the message programming failed @ adr 0x004800



    with old flasher ST7, the same operation was possible (with ST7lite29 or ST7F324)



    regards
  • Hello joubin,

    For reprogramming a target which is read out protected or for a target you do not know it is recommended
    to set the "Unsecure chip" option for AUTO programming.

    I recommend you to use the latest beta available from the following location:
    segger.com/cms/flasher-stm8-beta-software-version.html

    This might help you as well if you run into trouble with read out protection as the beta uses a new
    connect sequence and completely revised flash algorithm.
