[ECOS] MIPS32 gdb vectors question

[Tim Michals]

I'm investigating an issue with using GDB with the MIPS32 HAL.

Vectors.S has entry points for reset 0xbfc0_0000, interrupt vector
0xX000_0180 and debug 0xX000_0200


I thought when the BEV (Bootstrap) bit is not set, EXL, not already
processing an execption, is set to a 1 or 0 would indicate where the common
interruptmis defined, it can only be 180, or 200 but not both?


The problem is when a break instruction is serviced, it goes to the common
exception vector.  It is my understanding that is 0x8000_0180 if all of the
bits are set up correctly, not 0x8000_0200?

Thoughts?

Thanks,

Tim
