  • [ABANDONED] Error while reading netx90 flash

    Hello,

    i try to read the netx90 Flash with the J-Flash Tool. First i connect to the target:

    After successful connection i tried to read back the Flash via Target --> Manual Programming --> Read Back --> Range



    Then I get an error message:

    Why I can't read the flash from the netx90? What does this error mean?

    Furthermore I found out from another thread that the APP CPU is currently not supported:

    [SOLVED] Hilscher netx90 APP core dubugging

    Is the APP CPU planned for the future?

    Johannes
  • Hi Johannes,
    Thanks for your inquiry.

    Recently there was a fix for this device.
    Could you please download the latest J-Link Software and Documentation Pack version and give it a try with that one?
    You can find it here:
    segger.com/downloads/jlink/#J-…twareAndDocumentationPack

    If this does not help:
    Are you using an evaluation board or custom hardware?
    If evaluation board: Which one(including revision)?
    If custom HW: Does this problem also occur on an evaluation board?

    Regarding the APP core:
    Once we have access to the documentation we will add support for this device.
    This is planned for sometime next year.

    Stay up-to-date regarding J-Link:

  • Hi Johannes,
    Sorry for the delay in response.

    We recently had a customer who had a similar problem.
    According to him the problem was caused by some switches on the evaluation board, which were not set correctly.
    Could you please check this?

    Did you contact Hilscher support?
    They might also know something about this.

    Best regards,
    Fabian
