Re-configures and re-builds SOF with Zephyr using a pre-installed Zephyr toolchain and
the _defconfig file for that platform.
usage: $0 [options] platform(s)
-a Build all platforms.
-j n Set number of make build jobs. Jobs=#cores by default.
Infinite when not specified.
-k Path to a non-default rimage signing key.
-c recursively clones Zephyr inside sof before building.
Incompatible with -p.
-p Existing Zephyr project directory. Incompatible with -c. If
zephyr-project/modules/audio/sof is missing then a
symbolic link pointing to ${SOF_TOP} will automatically be
created and west will recognize it as a new sof module.
This -p option is always _required_ if the real (not symbolic)
sof/ and zephyr-project/ directories are not nested in one
another.
This script supports XtensaTools but only when installed in a specific
directory structure, example:
