Have a look at the ddd manual.

http://www.gnu.org/manual/ddd/html_mono/ddd.html

specifically, this section:

http://www.gnu.org/manual/ddd/html_mono/ddd.html#Machine-Level%20Debugging

on ddd:

I can't find *.S on uClinux08r1.

Can't open *.S file.

Can't set break on *.S.

*.c file can debug.

why?

DDD is simply gdb. so what exactly are you trying to do and what exactly is not working ?

我想用DDD调试应用程序，应用程序里面的C文件，是可以正常调试，设断点，单步都是可以的，但.S的汇编文件却不可以设断点，在DDD中也看不不到代码，请问是为什么？？？

provide some actual examples of what you're doing instead of saying "it doesnt work"

if you compile assembly files correctly as documented (for example, using the right flags like -g), we know debugging of assembly files works just fine

you havent shown that the file in question was (1) built with the proper flags and (2) even linked into your executable

verify both of these things first

生成的应用程序是可执行的，并且正常，就是用DDD调试时进不去（找不到）汇编文件，其他的C文件、H文件都是可以进去的。

I just tried things and they worked for me.

As Mike asked for - can you described exactly what you are trying to do, with the specific bfin-xxx-gcc/as commands?

Thanks

fdpic

my executable file is main,command are as follows:

host>ddd -debugger bfin-linux-uclibc main

on target:

bfin>gdbserver localhost:1234 main

(gdb) target remote target IP:1234

//Link to normal

(gdb)break main.c:50

//normal

(gdb) break bfin.S:50

// can't find bfin.S file,but bfin.S file is exist.

This is the crux of the problem, .S file can not find. C file normal.

You still never told me the information I asked for - what is the command line you are using to compile the applications? (turn the source into an object & link all the objects together).

two files is:main.c and bfin.S

Makefile as follows:

CROSS = bfin-linux-uclibc-

CC = $(CROSS)gcc

LDFLAGS += -W1

CFLAGS += -O2 -Wall -g

EXEC = main
