Hi all, I am trying to debug the FreeBSD 4.7 kernel using gdb remote debugging. However I am not able to do it properly. The kernel breaks in properly when I run "target remote /dev/cuaa1" command on my developement machine. However when I try to "step, next, continue" in the code it simply hangs, Or if I execute command to view backtrace, it doesnot show the complete stack and many of the entries are garbled giving the messages about "Ignoring packet error, continuing... " and "Reply contains invalid hex digits 116". Only once I was ablt to debug successfully. In my VMWARE setup also I can do the debugging without any problem. I even faced the same problem with different set of machines. Is there anything that I am missing in configuration or gdb stuff, or cabling problem? (I tested with kermit that the serial connection setup and is working fine, or it seems to be ;-() Any clues will be of great help. Thanks ans Regards, Manish _________________________________________________________________ Catch the Oscar fever.
