I took a copy of the floppy demo image on the Fiasco site, and try to use gdb on fiasco, from a PC/Linux with serial line, and gdb 6.4. I create a new grub entry to launch fiasco without the flags -noserial, -nowait and -nokdb, and the hello module. Boot seems ok, I suppose fiasco enters kdb and waits for a connexion from the serial line.
On the PC/Linux, I launch gdb, and enter commands :
set remotebaud 115200 target remote /dev/ttyS0
A dialog seems to establish with the target as I have the messages :
Remote debugging using /dev/ttyS0 Sending packet: $Hc-1#09...Ack Packet received: Sending packet: $qC#b4...Ack Packet received: Sending packet: $qOffsets#4b...Ack Packet received: Sending packet: $?#3f...Ack Packet received: S05 Sending packet: $Hg0#df...Ack Packet received: Sending packet: $p8#a8...Ack Packet received: Sending packet: $g#67...Ack Packet received: 0000000001000000041e03 Sending packet: $m0,8#01...Ack Timed out. Timed out. Timed out. ...
but the PC running Fiasco is resetting !!!
Any information will be helpful ... Thanks
