    • Hello,

      Thank you for your inquiry.
      The OMAP-137 device is not supported by J-Link. The OMAP-138 is however.
      If they are similar enough you could try to select OMAP-L138 instead of ARM9 in J-link commander.
      Simply specifying ARM9 will not work for this specific device as special handling is needed.

      Best regards,
      Nino

      I thought it set

    • Hello,

      what script do you mean?
      There is no script that we provide for the L138 device.
      Simply select the device name and connect should work without any scripts for the L138. If the L137 hardware is similar enough it should also work.

      Best regards,
      Nino

    • Hello,

      The script that you are referring to is ancient and is no longer compatible with the OMAP-L138 initialization in the current J-Link software.
      We do not recommend using it for OMAP-L138.
      Please understand that we can't offer support for old JLinkScripts that are not provided through the official release channels.
      As there is little market interest for the L137 and our resources are currently booked with more pressing projects we will not be adding support for that device at this point in time.

      However you can use the Script as baseline to implement support on your own. The L137 is a dual Core SoC so the Cores most likely need to be enabled through the ICEPick first.
      For more information consult the target devices manual and TI.

      Best regards,
      Nino
