Hi,
I have compiled linux kernel with arm-eabi toolchain on Ubuntu. The
kernel is working. Now I'd like to debug it with gdb.
I tried this command: arm-eabi-gdb vmlinux
My questions:
Which gdb should I use?
There is a gdb in the arm-eabi (downloaded with android) toolchain. This
will good?
I have tried that but I have got Don't know how to run. Try "help
target" error message.
I tried to set breakpoint to __init_begin, this works but when I tried
to start the debug with *start, run, cont* I have got this error
message.
