Hello Tommy,

thanks for your hints. We already use the OpenOCD from the RISC-V Github site.

We have done some instrumentation for JTAG and we see that OpenCD ignores second hart (it can enumerate it correctly but it does not initialize debug interface for it). On the first hart, single stepping doesn't work. Once we hit a break point we are stuck on this break point, e.g. continue stops immediately on the break point we hit without executing other code in between.
