  • Hello Max,

    Thank you for your inquiry.
    The necessary steps should be described in the target devices user guide.
    If not we recommend getting in contact with NXP support.
    The steps can then most likely be implemented using a J-Link Script file.
    More information about the script file interface can be found in the J-Link user guide UM08001.

    Best regards,
    Nino

  • maybe I didn't explain myself well: I am perfectly aware of the manual and of the existence of the described procedure.
    I wondered if J-Link would offer any shortcuts to do this, given the criticality: they are one time programmable, and an error could compromise the chip irreversibly.
    Moreover, the programming of the QSPI also involves an algorithm of several steps. However, this is provided by J-Link as functionality.

    In any case, I understand that Segger has not addressed with the issue leaving it entirely to the users, right?

    What exactly did you have in mind regarding OTP?
    Currently there is no "easy" out-of-the-box way to program OTP with J-Link for that device.
    So any customer implementing it for themselves should know what they are about to do.
    In any way depending on demand we might be posting a guide on how to program OTP for this device on our Wiki: wiki.segger.com/Main_Page
