HW debug support via JTAG

Hi,
I've been trying to use the JTAG based debug unit for debugging code in
the OR1200. I've been able to singlestep and get stack info etc. from
the hardware in GDB. What I really would love is HW breakpoint support!
When looking deeper into it I noted the discussion from mid January
about HW breakpoints and I wonder how much of this that is actually
implmented now. Is there breakpoint support in the verilog code? In GDB?
How much is left and is there anything I can do to help?

Daniel,
there is support in or1200 rtl for HW breakpoints in tagged revision
"rel_26". This is beta code however. The stub for this was implemented in
eCos but not using GDB JTAG interface.
regards,
Damjan

I've seen some code for it, but in absence of any implementation of the DSU matchpoint registers, it's probably not tested. So you might want to check the JTAG target code in gdb. If you want to debug or1ksim over JTAG, you need to reviev the JTAG implementation there, too. The DSU matchpoint registers in or1ksim are implemented and tested. Heiko |
