Description Juro Bystricky 2016-12-12 21:35:49 UTC 
When building Zephyr images, the resulting image is in ELF file format.
It would be nice to be able to run the image in qemu via a command such as:

runqemu zephyr.elf [command line arguments]

Presently we must use full paths, for example qemux86:

    $ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-i386 \
           -kernel ./tmp/deploy/images/qemux86/zephyr.elf \
           -nographic -machine type=pc-0.14 -display none -clock dynticks \
           -no-acpi -balloon none

or qemuarm:

    $ ./tmp/sysroots/x86_64-linux/usr/bin/qemu-system-arm  \
           -kernel ./tmp/deploy/images/qemuarm/zephyr.elf \
           -cpu cortex-m3 -machine lm3s6965evb -nographic -vga none

Sorry, I need more time to investigate how qemu boot elf.

Looks like this has been fixed already:
