Thanks for the link.
I have debugged u-boot to a point, it has relocated code, setup execptions / interrrupts etc and in main_loop().
At this point if I "Cont", I get pop-up from ddd
/.../u-boot-1.1.1/serial.c: No such file or directory.
There are 23 serial.c files in the tree. Those possibly relavent to me are
./cpu/mpc8xx/serial.c ./tools/gdb/serial.c ./drivers/serial.c
Just before relocating the code, I typed following statements
(gdb) symbol-file (gdb) add-symbol-file u-boot 0xbda000 (gdb) dir cpu/mpc8xx (gdb) dir board/fads (gdb) dir tools/gdb/serial.c (gdb) dir drivers/serial.c
Well, my question is why I am getting "No such file or directory" from ddd and how can I fix this problem.

It's not a trivial question, but a FAQ.
While doing source level debugging under ddd, whenever I do step, stepi, next or nexti I see green instruction pointer jump all over the code. e.g. it would go to first line, than third line, than 7 line. If I look at machine code window, it is running in normal predictable way.
