  • [SOLVED] Sfr Dump

    Hello,
    I would like to perform a dump of the sfrs on my ARM cortexM4 device, anyway my IDE (Atollic) only allows the view of the sfrs - not the saving or the export.
    Is there a way I could do it using my jlink device?
    I tried with Jlink.exe (savebin) but I got errors (Could not read memory) even if I am able to read flash addresses.
    Any hint would be very appreciated.
    Best regards,

    L.

  • Hi,

    SFR dumps should be done with great care...
    Pleas note that a savebin is designed for readbacks from RAM and flash where a bulk read can be performed.
    For SFRs this might be problematic, if there are gaps between the SFR blocks which cannot be read.

    If you just want a visualized dump, you can do it like this (Windows):
    JLink.exe -CommanderScript C:\MyCommanderScript.jlink > MyLog.txt

    C:\MyCommanderScript.jlink:
    // SFR 1
    mem32 0,1
    // SFR 2
    mem32 4,1
    // SFR 3
    mem32 8,1
    // SFR 4
    mem32 C,1
    // SFRs 5-8
    mem32 20,4
