Building the BSP for CCPF-SK
What is different between "MMP" and "MMP-dist".
 * MMP is minimal BSP which contains GFX/MMP evaluation package.
 * MMP-dist is MMP + some additional packages(For debug, development, benchmark, and so on).
 * MMP-dist release package(core-image-weston-release) is distributed on R-Car/Boards/CCPF-SK/GettingStarted
 * BSP is minimal BSP without GFX/MMP evaluation package.

Manual steps for building MMP
Note:
 * If you want to use build script, jump to


 * 1) Create a directory and switch to it
 * Warning! Yocto builds require a lot of disk space (up to 100 GB). Make sure you have got enough before starting the build.
 * 1) Clone basic Yocto layers:
 * 2) Switch to proper branches/commits
 * Another versions are not tested for compatibility.
 * 1) Switch to proper branches/commits
 * Another versions are not tested for compatibility.
 * Another versions are not tested for compatibility.


 * 1) Create $WORK/../proprietary folder, then download proprietary driver modules to it.
 * See also Required_packages
 * You should see the following files:
 * 1) Populate meta-renesas with proprietary software packages.
 * 2) Setup build environment
 * 3) Start the build
 * 4) Building image can take up to a few hours depending on your host system performance. After the build has been completed successfully, you should see the output similar to:
 * and the command prompt should return.
 * 1) Bitbake has generated all the necessary files in ./tmp/deploy/images directory. You can verify its content:
 * Image is a Kernel image, *.dtb is a blob file, core-image--.tar.bz2 is the rootfs, modules-.tgz are kernel modules.
 * 1) You can now proceed with Running Yocto images
 * and the command prompt should return.

Using build script

 * 1) Directory Structure
 * 2) Build script(build.sh)
 * 3) build
 * target_board_name is "h3ulcb" or "m3ulcb".
 * If the build completes successfully, all the necessary files are generated in a following directory:
 * target_board_name is "h3ulcb" or "m3ulcb".
 * If the build completes successfully, all the necessary files are generated in a following directory:
 * If the build completes successfully, all the necessary files are generated in a following directory:

Build SDK
Refer to Build SDK on the Yocto-Gen3 page.

Running Yocto images
Refer to Running Yocto images on the Yocto-Gen3 page.

Support list
Note:
 * "ok" - Function succeeded in the simple test as below.
 * "NT" - Function wasn't tested
 * Please connect USB 3.0 device to USB 3.0 port and USB2.0 device to USB 2.0 port.

CAN
Ex.) loop back
 * connect pin2 and pin6, pin3 and pin7
 * CCPF-SK-CAN.png

loading dtbo files
It requires to use device tree overlay in U-boot. Following is the example of using tftp. See also:
 * R-Car/Boards/Kingfisher/Yocto-Gen3/

Using Camera
Ex.) Show video captured by camera0 in weston.

Ex.) Show video captured by camera0 in weston.

Ex.) Save and show an image captured by camera0

How to crop or scale up/down video:
 * FAQ: How to crop the video which is captured by camera.
 * FAQ: How to scale up/down the video using vspfilter.

S2RAM
Push SW6 or execute 'systemctl suspend' to enter Suspend to RAM. it can wake-up by SW4.
 * May fail in NVMe connection state.

fan control
To use the fan control function, RL78 needs to be updated. This function can be stopped by "systemctl stop ccpfsk-fancontrol".

Known issues and limitations
