  • [CLOSED] JLink Pro, STM32F429 and flash > 1MB

    Hello,

    It seems, that my JLink Pro Debug Probe (HW 9.1, SW 4.98) on Keil MDK Arm 4.74 and 5.14 has problems while erasing the internal flash above 1MB.
    when i use "erase entire chip" everything is fine, if i use "erase sectors" than i become verify errors above Address 0x08100000.
    A ULink Pro on the otherside works fine.

    I there anything known to this issue?

    Tank you
    Martin

  • Hi Martin,

    We determined an issue which pops up when programming / erasing flashes > 1 MB.
    This issue has been crept in when we added QSPI flash programming support where we had to do some major changes in the J-Link DLL flash programming logic.
    We plan to create a fix later today / tomorrow (V5.00b).
