cuiziwei e21885b84a nuttx/boards:Uniform initialization format for init_array. (1) Keep the `.init_array` and `.ctors` symbols and sort them according to their initialization priority. (2) Exclude symbols ending with crtend.* and crtbegin.* to support c++ application.if we not exclude crtend.* crtbegin.* frame_dummy will be added when enable any c++ application with global variables, this symbol execution is problematic, removing it does not affect the application.

Getting Started
===============

1. Configuring and running
  1.1 Single Core
   Configuring NuttX and compile:
   $ ./tools/configure.sh -l mps3-an547:nsh
   $ make
   Running with qemu
   $ qemu-system-arm -M mps3-an547 -nographic -kernel nuttx.bin

Debugging with QEMU
===================

The nuttx ELF image can be debugged with QEMU.

1. To debug the nuttx (ELF) with symbols, make sure the following change have
   applied to defconfig.

+CONFIG_DEBUG_SYMBOLS=y

2. Run QEMU(at shell terminal 1)

   $ qemu-system-arm -M mps3-an547 -nographic -kernel nuttx.bin -S -s

3. Run gdb with TUI, connect to QEMU, load nuttx and continue (at shell terminal 2)

   $ arm-none-eabi-gdb -tui --eval-command='target remote localhost:1234' nuttx
