  • [SOLVED] STM32H743: **JLink Warning: Could not read memory location ... when trying to set soft RAM BP ... Erase Failed!

    Hello all,

    I am not able to erase the STM32H743 anymore using the Segger J-Trace Pro (SW interface) within Keil MDK v5.25, while the ST-Link V2 works - with otherwise identical configuration. Erasing/flashing the STM32F767 on the same board (only µC exchanged) works fine.
    The warnings/error are marked in red below.

    I suspect that the device "STM32H743IIKX" is not sufficiently supported by J-Link V.640 because I received a message box which asked me to select the device (see jpg attached).

    Any help is welcome!
    Regards
    Marcus
