  • [SOLVED] Loadbin with no reset

    Is it possible to perform a loadbin without resetting a device?
    I have a ram dump that I need to inject in the memory, but the device sets some output state before arriving at that point so I can not manually set PC and LR (and other registers).
    Any hint about that?
    my .Jlink file looks like this at the moment (writing to registers commented out becouse I am testing the reset part of loadfile):

  • Hello,

    You can override the reset functionality by passing a JLink script file to the JLink Commander that implements the ResetTarget() function.
    This will ensure JLink calls your custom reset function instead of the default target reset.

    Here is an example of how to override JLink functions:
    Overriding device specific connect

    To pass the script file to the JLink Commander, you can use the following command line option:

    Best regards,
    Simon
