  • Jlink-IAR-Icepick-Interrupt issue

    Hi

    I am using Jlink to connect to Cortex-M4 via IcePick.
    IDE used for this purpose is IAR.

    I am facing an unusual issue, CM4 is not jumping to ISR when the above mentioned combination is used for debugging.
    I can see that the NVIC registers are updated properly, means that the status register shows that the interrupts are generated.

    If anyone has seen this issue and solved it, please let me know.


    Some additional information

    I dont see the issue CCS+XDS+Icepick is used.
    Another piece of info is, when the Icepick is not used, but connected to CM4 directly (JTAG interface) using IAR and Jlink, this issue is not seen.

    Thanks
