Hi folks,

I'm sure it's an old problem but I can't find any answers on google. I currently try to debug a ARM processor with Tornado 2.0 with the serial WDB backend. Target and host are configured for 9600/8/1 and their ports are working. The target prints "WDB Ready" after booting, the shell displays "WDB: Ready" in the banner, too. Echo mode is working, too. And the host is sending packets over serial which I can't read as they are binary. But the target server can't connect. it always prints "Error: rpccore backend
client Timed out". This happens both on the first or second serial line.

The lines configuring the WDB are
"
#undef WDB_COMM_TYPE
#define WDB_COMM_TYPE WDB_COMM_SERIAL

#undef WDB_TTY_CHANNEL
#define WDB_TTY_CHANNEL 1
#undef WDB_TTY_BAUD
#define WDB_TTY_BAUD 9600
"

Network debugging is fine but for my problem I can't use it.
Has anyone solved this problem yet?

Thanks in advance,
Markus Pietrek
