Débogage croisé (x86/arm) Problème de connexion.
Bonjour à tous,
Voici mon problème, je cherche à utiliser GDB pour débugger une programme java tournant sur une plateforme ARM (Processeur ATMEL AT91SAM9G45).
J'ai d'abord voulu essayer avec un simple programme C compiler avec toutes les infos de debug, comme suit:
Code:
1

|
# arm-none-linux-gnueabi-gcc -g bug.c -o bugexearm |
Je le lance avec gdb-server sur la cible:
Code:

# gdbserver 192.168.1.[HOST]:8000 bugexearm
Process bugexearm created; pid = 6487
Listening on port 8000 |

readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.

Il n'y a pas de firewall, le port 8000 est libre...
Avez vous une idée du problème ?
Merci d'avance,
