  • [SOLVED] SAM ICE failed to connect to SAML11E16A

    I try to connect SAM ICE to SMAL11E16A via SWD (pin31, 32, reset, GND, VCC), but it reports "Failed to launch program, Error: numeric error 1" when I tried to debug the code in Atmel studio 7. Also, in Atmel Studio 7, Tools>> Device Programming , I set SWD clock to 2MHz, and click"Read", I got message " Error connection to device over SWD, Unable to enter programming mode. Verify device selection, interface settings, target power, security bit, and connections to the target device." I checked all above items, all look ok. I tried ATMEL ICE on my SAML11 PCB, it works with ATMEL ICE very well.
    With a J-link commander V6.40, I got some message below. From the message, looks like SAM ICE does not support cortex-M23 (used by SAML11), however, according to SAM L11 datasheet, the SAM ICE is supposed to work with SAML11. Does anyone have similar problem, any idea how to solve this problem? Thanks

  • Hello,

    Thank you for your inquiry.
    The SAM ICE you are using is based on a J-Link Base V8.
    Cortex-M23 are only supported on V9 or later:

    So to properly work with the L11 you would need to get a newer J-Link Base or SAM ICE.
    At Segger we offer the Trade in program for such cases so you can upgrade to the latest version with a discount:

    Best regards,
