  • J-link v8 + Coretex-M3 + ext Am29LV128ML don't work

    jlink v8, 4.08l driver. target board is stm32f103ze + ext nor (Am29LV128ML).

    project setting - core selected is Ctrotex-M3, init sequence has configured ok. when connect, check core and flash id is ok.

    question (1) : when Use target RAM is selected, all flash operate is failed. error info : Timeout while checking target RAM, core does not stop Failed to read back target memory.

    question (2) : Flash.csv file don't surport Am29LV128ML. why?

  • Hello zhanghg,

    >>question (1) : when Use target RAM is selected, all flash operate is failed. error info : Timeout while checking target RAM, core does not stop Failed to read back target memory.
    Could you please post your Project settings?
    Especially the settings at the "Target Interface" and "CPU" tab?
    Did you ensure that the RAM addr selected at the "CPU" tab is correct (E.g. 0x20000000 for internal RAM)?


    Best regards
    Alex

  • Hello zhanghg,

    currently Cortex-M3 + external Flash is not supported by J-Flash.
    We are working on it and it will be supported in the next beta version (V4.09g).
    There will also be a sample for the ST MB672 (STM32F103ZE) and external CFI flash.


    Best regards
    Alex
