I followed the instructions from the eCos documentation to
generate the toolset for TX39. I used GCC 2.95.2.
For gdb, I have used the tarball from ( 2000, Mar 13 ).
I have tried with GDB and Insight. Both fail. I am almost
cartain that it is the "flags" passed to the link. I just
cannot see what it is wrong. :-).
yes, I used the makefile for hello. I have tried -g, -ggdb. It did not work.
BTW, if I check the hello.o, I can see that the debug info it is
there. So, it seems to be something related with the link phase.
The '-g' flag is included with the flags passed to the linker.
I have tried this under Linux, and CygWin 20.1. Same results.
Thanks for your help.
