  • [SOLVED] Read manipulate and write fuse settings using J-link Commander Script Commands

    Currently we use a python script to read the Fuses (in effect 8 bytes) of a Microchip SAMD20J family chip (utilising AtmelStudio commands). We then manipulate a couple of bits using Python and re-write the fuses (8 bytes) again using Atmel Studio commands

    We can do a similar thing calling J-link Commander instructions.

    However we would like to do everything within a J-Link script and not rely on Python to do the 'bit' manipulation (of the fuse settings)
    Is this possible and can you give an example
  • Hello,

    Thank you for your inquiry.
    A JLinkScript can be used for something like this.
    You can use the MEM_API calls for this e.g. JLINK_MEM_WriteU32
    More information can be found in the J-Link user manual Um08001.
    Examples of JLinkScripts can be found in the J-Link install folder under /samples/JLink.

    Best regards,
    Nino
