We are pleased to announce our Yocto Kirkstone v23.2 Release for Tungsten Platforms. This includes our new Tunsgten510 SMARC and our Tungsten700 SMARC. This release is based upon the Mediatek iot-yocto-v23.2 (Kirkstone) release and includes our 5.15 kernel. Below you will find a download link for the images as well as detailed instructions for building including a features set.

Prebuilt Image

You can download the Yocto images from here:

Changelog 20240221 to 20240606:

  • fix suspend issues
  • add Quectel / Telit USB modem support
  • add MT320 Wi-Fi module power tables

How to Burn

The .zip archive include all the files to be flashed using fastboot.

First you need to enter fastboot mode from U-Boot prompt:

=> fastboot 0

If you are unable to get into fastboot mode from U-Boot, you can follow the this blog to recover your Tungsten platform.

Next, unzip image:

~$ unzip * -d Tungsten-Yocto
~$ cd Tungsten-Yocto

Finally, flash the image(s):

Flash bl2.img to mmc0boot0 partition:

~/Tungsten-Yocto$ fastboot flash mmc0boot0 bl2.img

Flash wic.img to mmc0 partition:

~/Tungsten-Yocto$ fastboot flash mmc0 rity-demo-image-tungsten-700-smarc.wic.img

Build procedure

This image uses the kirkstone-mtk-v23.2 branch of our yocto-manfiest repository.

To build the image, we recommend using a Docker Container so that you can build with a reproducible and stable build environment. Otherwise, you’ll need these packages installed as well as this repo tool that can be installed like this:

~$ sudo apt-get install repo

Now we are ready to build the image.

First, download the BSP yocto layers:

~$ mkdir ~/kirkstone-mtk && cd kirkstone-mtk
~/kirkstone-mtk$ repo init -u -b kirkstone-mtk-v23.2
~/kirkstone-mtk$ repo sync

Then, setup the environment for building.

~/kirkstone-mtk$ TEMPLATECONF=$PWD/src/meta-boundary/conf source src/poky/oe-init-build-env
~/kirkstone-mtk$ export BUILD_DIR=`pwd`

Finally, set the Tungsten MACHINE and bitbake rity-demo-image

~/kirkstone-mtk/build$ MACHINE=tungsten-700-smarc bitbake rity-demo-image

After some time this should build the same image as above, with the layers being at commits as per the time when repo sync was executed. If you are interested in each project revision at the time of the build, you can find a frozen manifest for those images here.

The image file will deploy to tmp/deploy/images/tungsten-700-smarc/rity-demo-image-tungsten-700-smarc.wic.img

Features list

The image built above contains the following components:

The next sub-sections will describe how to test most features.

GPU acceleration

To test GPU you can use glmark2:

root@tungsten-700-smarc:~# glmark2-es2-wayland --fullscreen



Once the eth0 interface is up, you can use iperf3 to check Ethernet performances:

root@tungsten-700-smarc:~# iperf3 -c

You can test Wi-Fi with nmcli as shown below:

root@tungsten-700-smarc:~# nmcli d wifi connect <network_name> password <password>

VPU decoding

You can test VPU with gstreamer:

root@tungsten-700-smarc:~# wget
root@tungsten-700-smarc:~# gst-launch-1.0 -v filesrc location=/home/root/SKYFALL-4K.mp4 \
    ! parsebin ! v4l2h264dec ! queue \
    ! v4l2convert output-io-mode=dmabuf-import capture-io-mode=dmabuf ! queue \
    ! waylandsink fullscreen=true
