Hi all,
I'm having some issues trying to remote debug my programs inside a TS-
7250 board. I'm currently working on a WinXp pc with Cygwin connected
through tcp to the TS-7250.
Let me tell you what I did so far:
1) I updated my cygwin version and I completely installed the "dev"
set of resources (ddd, gdb, make,? are all in it), anyway my gcc is
still the one in the "/opt" path from TS (I made an alias for it)
2) I configured the gdbserver compilation to be done with the arm-
unknown-linux-gnu-gcc (the one that has the alias to gcc?) and I
compiled it with the "make" command, no issue apparently
3) After starting cygwin, I just need to type in "startx" and, in the
following bash, "ddd my_program" and I'm ready to go with gdb handled
by ddd, both as a graphical interface or with a command line
4) When I first started "gdbserver" on my TS-7250 I had the
error "./gdbserver: error while loading shared libraries:
libthread_db.so.1: cannot open shared object file: No such file or
directory"
5) To solve this I added the file of my
pc "e:\cygwin\opt\crosstool\gcc-3.3.4-glibc-2.3.2\arm-unknown-linux-
gnu\arm-unknown-linux-gnu\lib\libthread_db-1.0.so" into the "/lib" of
my TS-7250 and I created a symbolic link with "ln ?
s /lib/libthread_db-1.0.so /lib/libthread_db.so.1". Now the gdbserver
works, but I'm not sure if I've done something correct or not,
moreover I linked that library, but my program uses the pthread
libraries actually and to have it running properly I had to insert
(in a previous stage) the "libpthread-0.10.so" file into "/lib" and
make the link "ln ?s /lib/ libpthread-0.10.so /lib/libpthread.so.0"
6) Now I'm trying to remote debug from the WinXp host my program
which is inside the TS-7250. I can with ddd or directly with gdb (in
both cases inside cygwin?), but I can have this setup to work. I mean
I'm able to connect them, on the target I call "./gdbserver
192.168.0.100:9737 my_program" and on the host I call "gdb
my_program" and then "target remote 192.168.0.58:9737". What happens
is that on the target side I read:
"Process splittex_ok created; pid = 120
Listening on port 9737
Remote debugging from host 192.168.0.100"
While on the host side:
"Remote debugging using 192.168.0.58:9737
0x00000000 in ?? ()"
If I now try to run the program writing "run" on the host I get:
" Starting program: /home/Marco/my_program
Error creating process /home/Marco/my_file, (error 193)"
and on the target appears:
"Killing inferior" and the gdbserver gets destroyed
I really don't know how to get through this issue? any idea?
Thanks again for your help!
Marco
