Hi,
I'm porting eCos to a MIPS architecture from TX39/JMR3904
template. My problem is that when I press Ctrl-C in GDB,
the program stops at breakpoint() (in hal_stub.c) which contains
only one instruction: HAL_BREAKPOINT(_breakinst). How
could I let the GDB stop exactly at the interrupted instruction
rather than the breakpoint instruction itself? By looking into
cyg_hal_user_break(), it seems that it might help if
CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS is defined,
since in that case it will call breakpoint() instead of calling
HAL_BREAKPOINT() directly, and it seems that breakpoint()
should handle the program counter stuff. But in fact the breakpoint()
contains only one instruction HAL_BREAKPOINT(), so it makes
no difference. Could cyg_hal_gdb_interrupt() help? Can I replace
breakpoint() with cyg_hal_gdb_interrupt() in cyg_hal_user_break()?
The following is my configurations:
- eCos v1.3.1
- GDB stubs
GDB Ctrl-C support enabled
GDB break support disabled
Startup type = ROM
loaded and run by ICE
- application
GDB stubs included
GDB Ctrl-C support enabled
GDB break support disabled
Work with a ROM Monitor = GDB stubs
Startup type = RAM
Thank you.
