Hi,
Can you run sdcdb? what version do you use? I have 2.1.9Ga and ,when
started,it responds with "connection refused" .I have followed Daniel's
suggestion to download the new version of ucsim(..2.37) and get the same
message...
For ddd try also ftp.gnu.org/ .../develop/ddd (i don't remember exactly) or
sunsite

Hi,
I just downloaded ddd and try to use it with sdcdb...is it possible?

I started with ddd --debugger sdcdb
so far it works, but when I load program (it loads ihx file) but when I 
wanna load source it writes "you have to load program first!"...
funny, isn't it.....

I wrote some times to the list that I found the following solution to
this problem:

- start ddd as you did
- place break on main by hand ("b main" command)
- start ("run")

When it stops on main, source appears!

I have DDD 3.2 and did what you said but when I set b main sdcdb says 
unknown command breakpoints (no matter) but sdcdb places it on wrong place 
(at the end of program)...

I started just sdcbd and effect is same so problem is in sdcdb not ddd...

what's wrong?

Hi,
be carefull sending replays to mailling list. It has to people to replay, 
one is who send it and second mailing list.
Effect is that replays to your mail comes twice. Ones from replayer, 
second from maillist.

So edit "To:" befor replaying mail.

Hi,
I found VERY strange bug. For testing I included files (as atachment).

It's little bit comlicated, but i'll try to explain:

My project has main file (test.c) which includes ONLY data and extern 
definition of extern function it needs (extern void func1(void)). It is 
linked with other peace of project by libraries (as you can see in 
makefile).
Each libraries makefiles are also included.

Problem is that everything works. Except that function func1 is NEVER 
included to test.ihx file. It has funny thing that function is called from 
main cycle like this
(*(ptst->pmodul))() // ptst->pmodul=func1
and that definition is in other file as global data
tst[]={
 {0,0,0,0,0,0}
 {func1,0,0,0,0,0}
}

But everything works under BC, DJGPP, GCC so another bug here.

Hi,
I tried to do some very easy example but when compiling has to be --debug 
option set otherwise it don't works. Until now I thought it needn't to be 
set, because .dbg file is always created......:-)

So now it work but very strange things happens. I can't watch any 
variable. Program jump everywhere (i think it's problem of optimalization).

Hi,

I think, me found a strange behaviour of the sdcdb and s51.
When I try to use a !<s51_command> I get "default" response:

------------------------
Program works fine, when I take look at variables via sdcdb's 'p'
command they're correct. When I use '!di' I got array of '0'.

Am I worng or is it wrong??

Please try s51 alone with the hex file. If you got same result then
s51 is wrong otherwise sdcdb should be checked.

Sorry, I forgot write it. s51 alone works fine.
When I use command which modifies *ram, then dump command appears be ok:

(sdcdb) !ss TH0 33
