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?
Thanks in advance,
Gavin
