Building and Running Zephyr Samples
===================================
There are several recipes that build various Zephyr samples.
Some may require a particular hardware, but some can run in QEMUs
Zephyr "philosophers" sample:
$ MACHINE=qemu-x86 bitbake zephyr-philosophers
You can run the created "philosophers" image in qemu (at this point
the various paths have to be entered manually):
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-i386 \
-kernel ./tmp/deploy/images/qemu-x86/zephyr-philosophers.elf \
-nographic -machine type=pc-0.14 -display none -clock dynticks \
-no-acpi -balloon none
The same sample, for ARM image:
$ MACHINE=qemu-cortex-m3 bitbake zephyr-philosophers
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-arm \
-kernel ./tmp/deploy/images/qemu-cortex-m3/zephyr-philosophers.elf \
-cpu cortex-m3 -machine lm3s6965evb -nographic -vga none
The same sample, for Nios2 image:
$ MACHINE=qemu-nios2 bitbake zephyr-philosophers
$ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-nios2 \

Building and Running Zephyr Tests

Zephyr test suite uses QEMUs for testing.
Presently only toolchains for ARM, x86, IAMCU and Nios2 are supported.
