  • [SOLVED] NXP iMX7 Solo

    Hi, I see at the wiki that NXP iMX7 solo is supported, but I don't find the device in the listings and I don't find any script-files on wiki.

    How do I use J-link commander with the solo series? I have had no success halting the processor with the dual core device scripts.

    Any help will be very appreciated.
  • Hi,


    thanks for your inquiry.
    The NXP iMX7S series devices (MCIMX7S3, MCIMX7S5) do neither have internal flash nor are they multi-core devices.
    Therefore no device-specific handling or J-Link script file is necessary.

    Debugging should just work when specifying Cortex-A7 as the device/core name.
    However, we will add MCIMX7S3 and MCIMX7S5 to the supported device list in a future version of the J-Link software & documentation pack in order to avoid further confusion.


    Best regards,
    Niklas

  • Ok, thanks. So do you have any idea why I cannot halt the processor? I do see "Found Cortex-A7 r0p5" message when I connect, and therefore I assume the JTAG interface is functional. But all other commands fail by "CPU is not halted !"

    I have measured that all voltages and clocks are within specifications. What can halt the processor then, and how to avoid it?
  • Hi,


    do I understand you correctly that the issue occurs if you do *not* use the dual core device scripts?
