[Gdb] Remote Debugging with gdbserver: HELP NEEDED on arm-device

[Chandra Shekhar Kumar]

1. We have built gdbserver with --host=arm-linux --target=arm-linux from the original source of gdbserver which comes with gdb 6.3 (source code)

2. Copied gdbserver to arm-device at /nand 

3. Copied /usr/local/arm/3.4.1/arm-linux/lib/libthread_db-1.0.so (which comes with ToolChain) at /nand

Now gdbserver is ready on device.

4. We have built gdb with --host=i686-pc-linux-gnu --target=arm-linux from the original source of  gdb 6.3

Now gdb is ready on the linux x86(host).

5. 
arm-device> ./bobsled &
pid = 155

arm-device> ./gdbserver /dev/tty --attach 155
Attached; pid = 155

Can someone help us in this regard because the gdb-stack is not shown.
