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
