Assertion failed: (jtag_trst == 0), function jtag_checks, file core.c, line 339.
Abort (core dumped)
Core dump is caused by hardcoded mem-ap dependency on jtag
(src/target/arm_adi_v5.c). When this is fixed, everything should work
fine in SWD. JTAG may need some facelifting after Transport layer
changes :-)
