Here's a trace of kgdb attempting to sync with a kernel over the serial port.. ---> "+" ---> "$Hc-1#09" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$Hc-1#09" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$Hc-1#09" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$Hc-1#09" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "-" <--- "$T058:e3375ac0;thread:186c5;#b5$" ---> "+" ---> "$qC#b4" <--- "T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qC#b4" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qC#b4" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qC#b4" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "-" <--- "$T058:e3375ac0;thread:186c5;#b5$" ---> "+" ---> "$qOffsets#4b" <--- "T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qOffsets#4b" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qOffsets#4b" <--- "$T058:e3375ac0;thread:186c5;#b5$T058:e3375ac0;thread:186c5;#b5" ---> "$qOffsets#4b" ---> "-" <--- "$T058:e3375ac0;thread:186c5;#b5$" ---> "+" "Couldn't establish connection to remote target " "Malformed response to offset query, T058:e3375ac0;thread:186c5;" note that: 1/ gdb CAN read the damned data.. this is obtained from ktrace. 2/ it prints out the packet in the error message. 3/ teh kernel is sending each message twice, in pairs. 4/ after kgdb finally sends a '-' (NAK) teh kernel sends ONE MORE which seems to be accepted Anyone have any clues? ~Received on Tue Dec 04 2007 - 03:14:08 UTC
