  • [SOLVED] Could not access to the RISC-V core once using the reset strategy = 1

    Hi segger experts,

    I'm working on a risc-v platform and using the reset strategy = 1 to reset the cpu. However, once doing that, the jlink could not access the core.
    1、Using the latest jlink software, v7.68;
    2、Connecting the SRST_N to the cpu core reset;
    3、Using the jlink commander, set the reset strategy = 1, that using RESET pin;
    4、Input the "r" to reset

    After doing the above steps, I can see the reset pin actively low with oscilloscope, but then it reports the error "****** Error: RISC-V: DMI access failed" just as the following picture shows.

    Any ideas about this error? :D

    Thanks in advance,
    Gavin
