Hi Everyone, I am trying to debug the linux kernel using remote GDB via serial port on MPC8xxFADS board. I built the kernel (2.4.4 from denx) with "kernel hacking-->Include kgdb kernel debugger" turned on. (I am not sure that turning on this flag is enough to support kernel debugging).
I got a bunch of ????? marks on serial console once the kernel gets run from "ppcboot", and then I start GDB with cmd "target remote /dev/ttyS0" on the host. The GDB got messages like "Ignoring packet error, continuing..." and then timeed out to close connection. Who can tell me what I am missing? Is it possible to debug linux kernel without any BDM/JTAG debugger? Any useful feedbacks are appreciated. Bo Yang ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
