Can I use the eCos mips64vr4300-elf-gdb with PMON, I tried to connect it
with PMON, even I set the remotebaud to 9600, which is default value for
PMON, when I tried to "target remote /dev/ttyS0", the response is,
"Couldn't establish connection to remote target, Malformed response to
offset query, qOffsets".

Where I can find a working verison gdb with PMON in Linux? The board comes
together with a Cygwin version toolchain, I found it is hard to compile in
Linux platform. I am just wondering why the gdb working with eCos GDBstubs
can not working with PMON? By the way, I changed the
CYGSEM_HAL_USE_ROM_MONITOR option to PMON when I compile the eCos tests. Any
hints? Thanks!

Rgds,
