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
|
