ORPSoC cycle accurate model RSP server issues #139
Closed julius opened this issue about 14 years ago

Using OpenRISC ports of either gdb-6.8 or gdb-7.2, debugging via RSP to the cycle accurate model of ORPSoC now has several issues.
gdb-6.8 issues are that instruction stepping appears to continue execution rather than step execution, the load command receives multiple "packet errors" and then the system appears not to respond properly after loading.
gdb-7.2 cannot connect at all, and crashes the model.
I suspect a more recent version of Jeremy Bennett's RSP server, and better integration are needed.

This is a known problem with GDB 7.2 and GCC 4.5.1. GDB 7.2 introduced some new packets, which are not handled by the RSP server. That can be easily fixed.

The other errors (with GDB 6.8) appear to be connected with the move to DWARF-2 debugging format (it used to be STABS). We're still working on that one.
