Openembeded /Yocto BSP layer for R-Car DU test

(Click here for Japanese)

Overview

This layer provides recipes of kms-tests script for R-Car DU test for use with OpenEmbedded and/or Yocto.

Dependency

This layer depends on meta-renesas layer:

• URL: https://github.com/renesas-rcar/meta-renesas
• branch: dunfell

Build

Assume that the yocto environment has already been extracted to /path/to/work/yocto.

$ cd /path/to/work/yocto
$ ls
build  meta-openembedded  meta-renesas  poky

The build directory is present only if it has already been built.

Add this layer and configure for test

Extract this recipe to /path/to/work/yocto/.

$ git clone https://github.com/igel-oss/meta-rcardu-test.git

Create bblayer.conf and local.conf according to this build procedure.

$ . poky/oe-init-build-env
$ cp ../meta-renesas/meta-rcar-gen3/docs/sample/conf/salvator-x/poky-gcc/mmp/*.conf ./conf/
$ mv conf/local-wayland.conf conf/local.conf

Add this layer to bblayer.conf.

 BBLAYERS ?= " \
   ${TOPDIR}/../poky/meta \
   ${TOPDIR}/../poky/meta-poky \
   ${TOPDIR}/../poky/meta-yocto-bsp \
   ${TOPDIR}/../meta-renesas/meta-rcar-gen3 \
   ${TOPDIR}/../meta-openembedded/meta-python \
   ${TOPDIR}/../meta-openembedded/meta-oe \
+  ${TOPDIR}/../meta-rcardu-test \
   "

Add the following to local.conf so that kms-tests is added to rootfs.

DISTRO_FEATURES_append = " dutest"

Build rootfs image and SDK

Create rootfs and poky SDK.

$ bitbake core-image-weston
$ bitbake core-image-weston -c populate_sdk

Build kms-tests standalone

Yocto build installs kms-tests to rootfs. So please skip this section if you don't need to build kms-tests standalone.

Install poky SDK

Install the poky SDK on the host PC by executing poky-glibc-x86_64-core-image-weston-aarch64-salvator-x-toolchain-<poky version>.sh created in build/tmp/deploy/sdk/. Default install path is /opt/poky/<poky version>/.

$ cd tmp/deploy/sdk/
$ ./poky-glibc-x86_64-core-image-weston-aarch64-salvator-x-toolchain-<poky version>.sh

Build kms-tests

Assume kms-tests is located at /path/to/work/kms-tests. Run make with PYTHONPATH, CFLAGS, and LDFLAGS set as follows:

$ cd /path/to/work/kms-tests
$ /opt/poky/<poky version>/environment-setup-aarch64-poky-linux
$ PYTHONPATH=`echo -e "import crcmod\nprint(crcmod.__path__[0])" | python3 | sed -r 's/(\/.*\/)crcmod/\1/'` CFLAGS="--sysroot=${SDKTARGETSYSROOT}" LDFLAGS="--sysroot=${SDKTARGETSYSROOT}" make

To install, set the installation path to INSTALL_DIR and run make install.

$ make install INSTALL_DIR=/path/to/target/directory

Run Test on R-Car Board

After the board is started, execute script from the console.

root@salvator-x:~# kms-test-formats.py

kms-tests script install path is /usr/bin/
