GDB stubs build problem for vrc4373


One problme bothers me is, I have never succeeded in building a GDB stub for
vrc4373 by using a CVS version snapshot. Actually only the binary version
provided in eCos 1.3.1 release works for me, whenver I tried to build a new
one by using the CVS version or any snapshot of source code, I just got a
dead monitor without any response. Basically I did "ecosconfig new vrc4373
stubs" and then make it. I was really puzzled me whether the CVS version (or
the Open Sourced version) really the same as what RedHat playing with. Or we
really need to buy a comercialzed GNUPro toolchain to make the compiled code
working. I can compile my code starting up in RAM and debug it using the
binary GDB stub provided in eCos1.3.1 release,  but why I can not make a
working GDB stub by myself? Anything I missed?

As you may know, I am trying to port the vrc4373 code to vrc4375 board, the
most important thing is to get a running stub, I want to make sure I can
build a working gdb stub for vrc4373 before I can change it to working on
vrc4375 board. I have been trying this for several days, no outcome. Any
advices? Thanks, and help, please... :-/
