Hi All,
Qemu is a machine emulator software with inbuilt GDB server support for remote debugging through TCP.
I am trying emulate VerstailePB board and boot linux kernel over it . I am freezing the execution of cpu after restart and connecting it from a gdb client . In my case am using ARM DS-5 as gdb client to start the connection to Qemu .
I am get following error after connecting to Qemu from ARM DS-5 when i run the command "continue" to start the execution of cpu to boot linux kernel over VersatilePB board.
ERROR(CMD441-TAD8-NAL60):
! Continuing failed
! Unable to run device gdbserver
! Remote gdbserver did not recognize message

Hi Shabarish,
It looks like the version mismatch between gdb client and gdb server. But I also notice that you are trying to do kernel debug, aren't you? gdb solution is more suitable for application debug.
And DS-5 was not designed to work with Qemu officially. With some hacks, it might be able to do application level debug via gdb/gdbserver routine with Qemu. If you want to do kernel debug, you might want to build in gdb stub into the kernel.
The official supported emulator/simulator is Fast Models/FVP(Fixed Virtual Platform). Not sure which DS-5 version you are using, but certain DS-5 editions include a FVP which you can have a try.
Best regards,
George
