This feature for Ultra96 boards is implemented in the 2021.1 release.

To use this feature, enable the below debugs in the PMUFW order to shut down directly.

PetaLinux:

The compiler flags should be applied to <plnx-proj-root>/project-spec/meta-user/recipes-bsp/embeddedsw/pmu-firmware_%.bbappend recipes

Note: For information on how to apply a patch to recipes in PetaLinux, please refer to (UG1144) or https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842475/PetaLinux+Yocto+Tips

1) Create a embeddedsw directory and pmu-firmware_%.bbappend recipes in the meta-user layer as shown below.

$ mkdir -p <plnx-proj-root>/project-spec/meta-user/recipes-bsp/embeddedsw
$ touch <plnx-proj-root>/project-spec/meta-user/recipes-bsp/embededsw/pmu-firmware_%.bbappend

2) Modify the pmu-firmware_%.bbappend file with the below content using a text editor:

$ vim <plnx-proj-root>/project-spec/meta-user/recipes-bsp/pmu-firmware/pmu-firmware_%.bbappend

# pmu-firmware_%.bbappend content
# For Ultra96-V1 boards
ULTRA96_VERSION = "1"

# For Ultra96-V2 boards
# ULTRA96_VERSION = "2"

YAML_COMPILER_FLAGS_append_ultra96 = " -DENABLE_MOD_ULTRA96 -DENABLE_SCHEDULER -DENABLE_DIRECT_POWEROFF_ULTRA96"

3) Clean the pmu-firmware sstate cache and rebuild the pmu-firmware recipes:

$ petalinux-build -c pmu-firmware -x cleansstate
$ petalinux-build -c pmu-firmware

Yocto:

The compiler flags should be applied to <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/embeddedsw/pmu-firmware_git.bbappend recipes

1) Modify the pmu-firmware_git.bbappend file with the below content using a text editor:

$ vim <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/embeddedsw/pmu-firmware_git.bbappend

# pmu-firmware_%.bbappend content
# For Ultra96-V1 boards
ULTRA96_VERSION ?= "1"

# For Ultra96-V2 boards
# ULTRA96_VERSION = "2"

YAML_COMPILER_FLAGS_append_ultra96 = " -DENABLE_MOD_ULTRA96 -DENABLE_SCHEDULER -DENABLE_DIRECT_POWEROFF_ULTRA96"

2) Clean the pmu-firmware sstate cache and rebuild the pmu-firmware recipes:

$ bitbake pmu-firmware -c cleansstate
$ bitbake pmu-firmware
