Hi, Iñigo and I work together. The results he presented were obtained with the mentioned OpenOCD patch already in place, which I submitted recently.
There is definitely a difference between OR1200 and MOR1KX in handling the OpenOCD requests via the ADBG and debug interface. The purpose of reporting this problem is to help towards fixing these problems in MOR1KX. Unrelated to this, has anyone noticed that OR1200 simulates much faster in Verilator as compared to MOR1KX?
