Does Hwacha support GDB for debugging？ #472

Closed kangrl666 closed 4 years ago

kangrl666 commented 4 years ago

1.Does Hwacha support GDB for debugging？

2.Run command“spike -H --rbb-port=9824 --extension=hwacha vec-vvadd.riscv”，this program doesn‘t start halted，directly output results，not allowing a debugger to connect。

But run command“spike -H --rbb-port=9824 vvadd.riscv”，this program start halted。spike connects openocd， openocd connects GDB，both are ok，debugging is ok。

why？the command“spike -H” is right for RISC-V，but not right for Hwacha? how to solve the problem for debugging Hwacha instructions？

I've responded on the hwacha issue and think we should keep the discussion there. Closing this now.
