Hi,
I am trying to setup the remote debugging.
Here are the steps that I follow
1) Target: nvram boot-args="debug=0x14e"
2) Reboot target.
3) Host: arp -s <target> <mac address>
4) Target: kextload -l -s /tmp my_driver.kext
5) Target: tar -cvf sym.tar /tmp/*.sym
6) ftp host, put sym.tar, also put source
7) Host: untar sym.tar
8) Host: gdb mach_kernel (from th SDK)
9) Host: (gdb) target remote-kdb
10) Host: Add the symbols
11) Target: kextload -m my_driver.kext
12) Target : Run test so that systme becomes non-responsive
13) Target: Give NMI to enter into debugging
14) Host: (gdb) attach target
15) source kgmacros
16) showallstacks
17) Get the message: Cannot access memory at address 0x0
What could I be missing?
Thanks,
Lalit.
