Since last time I tried Android and Ubuntu on the Wandboard, a few things happened. I’m not talking about Wandboard Quad announcement, but instead I received a Class 10 SD card, which makes the system so much responsive, and a RS232 to USB adapter so that I can access the serial console. So today, I’ll publish some benchmark results on Wandboard Dual since none appear to be available, and play a little with the serial console. A few things also happened on the operating systems side with more distributions now available for the board.
Prerequisites
I ran benchmark in Android, so I installed the latest Android 4.1.2 image (11th of April 2012) to my new SD card (ADATA 16 GB Class 10), and contrary to my poor experience on a 4GB Class 4 micro SD, everything was very fluid. I’ve also installed Google Play in order to install the applications. To do so in any device, you need to download the latest version for your Android version from http://goo.im/gapps. In our case (Android 4.1.2), we need to download gapps-jb-20121011-signed.zip, extract it and copy the files in the micro SD card in a Linux PC:
|
1 2 3 4 5 6 |
cd ~/ mkdir gapps-jb cd gapps-jb unzip ~/Downloads/gapps-jb-20121011-signed.zip sudo cp ~/gapps-jb/system/* /media/system/ -rf sync |
|
1 2 3 4 5 6 7 8 9 |
wget http://downloads.androidsu.com/superuser/su-bin-3.1.1-arm-signed.zip unzip su-bin-3.1.1-arm-signed.zip adb push system/bin/su /mnt/sdcard/su adb shell mount -o remount,rw /system busybox cp /mnt/sdcard/su /system/xbin/su chmod 6755 /system/xbin/su sync reboot |
Antutu and Quadrant Benchmarks on Wandboard Dual
|
1 2 3 |
CPU: Freescale i.MX6 family TO1.1 at 792 MHz CPU is 80 C, too hot to boot, waiting... Temperature: 73 C, calibration data 0x59952b5f |
With 6190 points, Wandboard Dual performance is between Amazon Kindle Fire (TI OMAP4430) and Samsung Galaxy Nexus (TI OMAP4460), which seems about right. This also compares to 8516 points in Hi-802 (Freescale i.MX 6 Quad), with the quad version getting double the score for integer, over 50% more for RAM and floating-point tests. Surprisingly 3D graphics results are better in Wandboard Dual (1771) compared to Hi-802 (1272) in Antutu. This is an anomaly that could either be due to a different Android version (4.0 vs 4.1) and/or better drivers, or the orientation during the test really affects the results.
Quadrant benchmark places the device just below LG Optimus 2X (Nvidia Tegra 2) and Galaxy Nexus, so no surprises here.
Setting-up the Serial Console on Wandboard
Many boards provide access to the serial console via +3.3V TTL signals, so you can just connect a TTL to USB board. The Wandboard uses RS232 signals, so you’ll need a different type of debug board, or simply a null-modem cable if your computer features a DB-9 serial connector. Mine does not, so I bought a cheap RS232 to USB converter. Build quality is poor, but it does the job. At first, I thought I could just connect it directly to the Wandboard, but it also needs a null-modem cable, Since I don’t have one myself, I used three breadboard wires instead connecting Tx, Rx, and GND following the diagram below:
I only connected pin 2,3 and 5, and ignored the other connection which are not needed for our purpose. The picture below shows the end result. I just connect the RS232 to USB converter to a USB hub to access it from Linux or Windows.
In Linux (Ubuntu 12.04), the converter is immediately recognized, and you can just access the serial port with minicom, after setting up 115200bps/8n1 connection to /dev/ttyUSB0. In Windows, you’ll need to install a driver either from the provided CDROM, or download CH341SER.zip.
For reference, here’s the boot log from Android 4.1.2:

Images, BSPs, and Source Code for Wandboard Solo/Dual/Quad
Software support, although not 100% perfect, appears to be now much better than before, both in terms of stability and features, and the number of available images.
As of writing, Wandboard provide 2 Android images on their download page:
- Android 4.2.2 Preview – Android 4.2 will become the official image, but this currently very much work in progress with no Bluetooth, limited UVC camera support, and probably quite a few bugs. The image is available for both Wandboard Dual and Quad. Source is not available yet, but soon will be.
- Android 4.1.2 – Current somewhat stable image for Wandboard Dual and Solo. Source is available for download as a tarball, and via their git repo.
Linux kernel source is available as a tarball or via Wandbaord’s git repository. Several Linux based distributions and BSP are now available:
- Ubuntu 11.10 – For Wandboard Solo/Dual and Quad with GPU hardware acceleration, and VPU video decoding.
- Freescale Yocto BSP – Wandboard Solo and Dual are officially part of Freescale i.MX6 Yocto BSP. You can build it yourself, or download some prebuilt image such as the one with xfce desktop environment
- Buildroot – Buildroot for Wandboard Dual can be built. Most features seem included, but gstreamer appears to be missing.
- Ubuntu 13.04 / Debian 7 – There are instructions to retrieve minimal rootfs for those 2 distributions on Wandboard Wiki, but those probably do not support GPU / VPU.
- Community Squeeze OS – You may have never heard of that one, I hadn’t. CSOS, based on Fedora 18, is used by the “Community Squeeze Player project”, a network music player, similar to Logitech Squeezebox The image is only available for Wandboard Dual for now. Visit slimdevices forums for details.
Wandboard is also part of mainline U-Boot, so you can just get the source from DENX, build it for Wandboard, and put it on your board. There’s also some work to get Wandboard into Linux mainline, but I’m not really sure about the status.

The cpu is hot at 80C ! Is that temperature right ?
It is trobulesome, because I think there is no place (holes) to fix a small cooler.
Do you have made any test with an Ubuntu image ? Can you tell if the system is fast and stable ?
Thanks and excuse me my bad english.
@Leo
I’m not sure, although it felt quite hot when I touched it. You could always place a heatsink. I only saw this problem once.
I made some tests last time http://www.cnx-software.com/2013/04/01/wandboard-releases-updated-android-and-ubuntu-linux-images-and-source-code/ . But I used a Class 4 SD, so it was relatively slow, but I did not have reliability issues.
No idea if you ran all the tests similar as above picture (the picture which explains the serial cable). But please turn the Wandboard around so that the connector board is at the bottom and the CPU is visible on top.
Hot air is always travelling vertically upwards. turning the board around makes it difficult for the CPU since you block any airflow possible.
Regarding Android / bluetooth. This has been fixed. UVC camera support is also improved. The complete sourcecode repository will be available Thursday/Friday this week.
@wandboard
Yes, I ran the test in this configuration, and turned it around to complete testing.
“The board also overheated once […] and froze.”
That sentence made me kinda laugh.
