RZ/G2L EVK - Quick Start Guide
The packages that needed to be installed are in the following link:
Renesas VLP Packages
These packages need to be extract inside the /work directory by using the command below.
tar xzvf rzg.tar.gz
The /rzg folder is then reopen inside the container that you created in the tutorial before.
Check the user that exist inside the github by using the following code:
git config --global --list
If the username and email not exist or incorrect, you can use the following code to modify it:
git config --global user.name <"your-username">
git config --global user.email <"you@example.com">
Next, make a new directory name yocto under the /rzg directory.
mkdir yocto
and move to the directory.
cd yocto
Next, download and extract the following zip files into the /rzg/yocto/ directory:
RZ/G Verified Linux Package zip file
RTK0EF0045Z0021AZJ-v3.0.6-update3.zip
RZ MPU Graphics Library zip file
RTK0EF0045Z0021AZJ-v3.0.6-update3.zip
RZ MPU Video Codec Library zip file
RTK0EF0045Z15001ZJ-v1.2.2_EN.zip
Check the working directory to confirm the working contents by using the following command:
ls -l
Make sure that all the packages are extracted successfully.
extra
meta-gplv2
meta-openembedded
meta-qt5
meta-renesas
meta-rz-features
meta-virtualization
poky
Since the VLP packages you downloaded previously is the older version, you need to patch it into the new update3 using the following command: (This is all done under the /rzg/yocto/ directory)
patch -p1 < ../RTK0EF0045Z0021AZJ-v3.0.6-update3/vlpg306-to-vlpg306update3.patch
Next, add the following patch files of the GStreamer and the Qt Toolkits into the /rzg/yocto/ directory. The download links are provided below:
Apply the following patch files inside the same directory:
patch -p1 < ../extra/0001-rz-common-recipes-debian-buster-glibc-update-to-v2.2.patch
patch -p1 < ../extra/0001-rz-common-linux-update-linux-kernel-to-the-latest-re.patch
patch -p1 < ../extra/0001-rz-common-gst-plugins-bad-Depending-bayer2raw-if-lay.patch
Apply a patch file to add the GStreamer Moil Plugin.
patch -p1 < 0001-gstreamer-moil-plugin.patch
Apply a patch file to fix the Qt Smart Home URL.
patch -p1 < 0002-fix_qtsmarthome_url.patch
When applying the patch files of the GStreamer Moil Plugin and the Qt Smart Home URL, remove the .patch and press TAB to correct the command.
Next, initialize a build using the oe-init-build-env script in Poky and set environment variable TEMPLATECONF to the below path:
TEMPLATECONF=$PWD/meta-renesas/meta-rzg2l/docs/template/conf/ source poky/oe-init-build-env build
Next, add necessary layers for AI application to build/conf/bblayers.conf (configration file for layers).
bitbake-layers add-layer ../meta-rz-features/meta-rz-graphics
bitbake-layers add-layer ../meta-rz-features/meta-rz-codecs
bitbake-layers add-layer ../meta-qt5
Next, download the downloads.tar.gz on your PC using the link below.
Then, you can transfer your files from your PC onto the Ubuntu OS by using the following command: ( Please replace the userand ip-addresswith the PC that you running on )
scp .\downloads.tar.gz user@ip-address:/home/user/work/rzg/yocto/build
After done transferring, extract the downloads.tar.gz using the following command:
tar xzvf downloads.tar.gz
Next, run the following command to build the weston image.
MACHINE=smarc-rzg2l bitbake core-image-weston
Add these lines of code into the local.conf located inside the /rzg/build/conf/local.conf
QT_DEMO = "1"
DL_DIR = "${TOPDIR}/../downloads"
SSTATE_DIR = "${TOPDIR}/../sstate-cache"
IMAGE_INSTALL_append = " kernel-module-uvcvideo "
EXTRA_IMAGE_FEATURES_append = " ssh-server-openssh "
IMAGE_INSTALL_append = " curl graphviz "
IMAGE_INSTALL_append = " gst-instruments gst-shark"
PACKAGECONFIG_append_pn-gstreamer1.0 = " tracer-hooks "
Next, the lsblk command can be used to check the usb device connected to the port of the PC.
If the USB disk have already mounted, you need to use the command:
sudo umount
to unmount the USB to ensure clean install of the build file into the SD card.
To mount the build file into the SD Card, you use the command:
sudo bmaptool copy core-image-weston-smarc-rzg2l.wlc.gz /dev/sda
