    Hello Fabian,

    I would like the manufacturer to write automatically the current time and date in the DATA FLASH (using a script with JLINK_MEM_WriteU8(), etc), right next to the serial number (SN) programmed with JFLASH.

    Regards.

  • Hi,
    As already mentioned, this will not be possible via a J-Link Scriptfile.

    But you can do this via a J-Flash:
    1. Create a .bin file with the desired timestamp via a script (e.g. .bat or .py).
    2. When opening J-Flash add the command line "-merge<FILENAME>.bin,<ADDR>" (without quotations).

    Example in a production setup:
    JFlash.exe -openprjC:\Projects\Default.jflash -mergeTimeStamp.bin,0x12345678 -auto -exit

    Does this solution work for you?

    Best regards,
    Fabian

    Thanks for the example Fabian. It works well and does what I want. However, I think it's a bit complicated to send it to production because of the need to use command prompt.
    Wouldn't there be some way to make an automatic merge without using command prompt? If not, would it be added in future versions?

    Regards

  • Hi,

    Could you elaborate what you mean with "complicated"?
    As mentioned above, you could do this with a script, so your production would only need to click a .bat or .py file.
    Your bat or py script could do the following:
    - Get current date/time
    - Write date/time into a .bin file
    - Call J-Flash with the above command line

    You would only have to set this up once and your solution would be portable and working out of the box.

    This is not planned and there are currently no plans to add this feature, since it is very user and device specific.

    Best regards,

    Yes, you are right, using a .bat file is much easier. At first I didn't think of a ".bat" file, but wrote it on the command line.

    This is what I have done and it works. This question is solved.

    Thanks for your help.
