Ubuntu 12.04 Now Boots on Rockchip RK3188 mini PCs (T428, MK908, Rikomagic MK802 IV…)

June 15th, 2013 cnxsoft 17 comments

After the release of the RK3188 Linux kernel source code last week, Ian Morrison (Linuxium) has managed to boot Ubuntu 12.04 with XFCE desktop on Tronsmart T428. However, as Tronsmart refused to release their source code, further Linux development is likely to happen on Rikomagic MK802 IV, because Rikomagic released the code for their device, so development work will be easier.

AFAIK, this is the first time Linux boots natively on RK3188 devices, so it’s still early stage (no Wi-Fi, Bt or graphics acceleration), but if you still want to give it a try here are the instructions (for T428):

Create a SDCARD with an Ubuntu 12.04 root file system on it and ensure it is labeled as “linuxroot” (Visit Slatedroid for details)
Flash your RK3188 minipc with rooted stock 4.1.1 ROM. (May not be needed if you ROM is already rooted)
Boot Android, and install Android Terminal
Flash t428-3.0.36-linuxium-test+-kernel.img as recovery.img with RKAndroidTool. (~~I can’t find the binary, and my Internet connection does not allow me to access all files right now, but you may want to follow the build instructions to get the image.~~) [Update: See comment for kernel binary and modules]
Reboot your mini pc, start the Terminal in Android, type “su” to become root, and finally type “reboot recovery” to reboot into Linux.

It’s safe to try as those instructions should not affect your Android installation.

Ian also ran some benchmarks from Phoronix Suite to compare Linux performance in a chroot in Android via Linux Complete Installer (T428-ubuntu-complete) and native Linux (t428-linuxium). The third column is for an RK3066 mini PC (iStick A200) running Linux natively.

None of those tests do not require a graphical interface, and results are pretty close. Native Linux has a slight advantage with many of them, but for some reasons Linux running in Android appears to have a clear edge for PyBench.

PicUntu developers are already aware of this progress, so you can expect RK3188 PicUntu soon. Further details are available on Mini PC G+ Community including logs, kernel config, and some documentation.

Wandboard Dual Benchmarks, Serial Console Fun, and Distributions List

June 11th, 2013 cnxsoft 5 comments

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:

cd ~/
mkdir gapps-jb
cd gapps-jb 
unzip ~/Downloads/gapps-jb-20121011-signed.zip 
sudo cp ~/gapps-jb/system/* /media/system/ -rf 
sync

In order to capture screenshots, I also had to root the device using the following steps from a Linux PC with Wandboard connected to the PC via its mini USB port:

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

At this point you should get a rooted image with a working Google Play on the Wandboard, the final step is to install superuser so that you can control which apps get root access.

Antutu and Quadrant Benchmarks on Wandboard Dual

The screen will rotate with both Antutu 3.3 and Quadrant benchmark, so they are performed in portrait mode. This is using full screen, so the results should still be valid for comparison. The board also overheated once during Antutu’s 3D Graphics benchmarks, and froze. A immediate reboot of the board showed the following message:

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

I turned the board around so that i.MX6 SoC can get better ventilation, and the benchmark could complete.

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:

Source: Microtik

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.

Rockchip RK3188 Linux Source Code is Now Available

June 6th, 2013 cnxsoft 6 comments

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs.

Let’s have a look:

git clone git://github.com/aloksinha2001/Linux3188.git
cd Linux3188

Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
./make_kernel_ruikemei.sh

After just over a minute, success!:

  LD      vmlinux

  SYSMAP  .tmp_System.map
  OBJCOPY arch/arm/boot/Image

   Image:  kernel.img is ready

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188.

Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs:

rk3168_86v_defconfig
rk3188_dongle_defconfig
rk3188_ds1006h_defconfig
rk3188_ds1006h_v1_0_defconfig
rk3188_hotdog_defconfig
rk3188_LR097_defconfig
rk3188_magicwand_defconfig
rk3188_steak_defconfig

However, in arch/arm/mach, there are only board files for rk3188-box and rk3188-ds1006h.

How to Find Configuration Options Quickly in Make Menuconfig

May 23rd, 2013 cnxsoft 5 comments

If you’ve ever compiled the Linux kernel, you’ll know make menuconfig is the command line used to unset/set options, disable/enable modules in order to match your hardware and requirements. I used to simply browse in the menu to find the option, and just remember the correct path. Sometimes I just looked at .config to locate the option I needed, and the possible path in make menuconfig. The first time you use a new option it can be time consuming. But I’ve just found there is a better way via Google+.

“/” is actually available in make menuconfig, just like it is in vi/vim. If you want to enable NFS server in your kernel, press “/”, and search for NFSD.

It will show the list of results with “NFSD” strings. NFS server support is right at the top, and the path is shown to be File Systems->Network File Systems. The neat thing is you don’t have to remember or note the path, as you can just press the number between parenthesis on the left of the option location, in this case (1), and it will take you directly there.

But what if you’re searching for a string with lots of results such as PCI. The actual CONFIG_PCI is just buried in the search results. The solution is to use regular expressions. If you just want to find “CONFIG_PCI”, press “/” for a search, and “^PCI$” to find the exact match.

Great! Press “1″ to go to the option, and enable PCI in your kernel. You can use other regexps as well.

Linux 3.9 Release

April 29th, 2013 cnxsoft No comments

Linus Torvalds has announced the release of Linux Kernel 3.9:

So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t actually want to do a final release last week. Please don’t do that.

Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting.

Also, this obviously means that the merge window is open. I won’t be merging anything today, but if you start sending me your pull requests (Konrad already sent in his Xen pull request for the 3.10 merge window a week ago), tomorrow the flood gates start opening..

Linux 3.8 brought file systems enhancement for Btrfs, XFS and ext-4, introduce F2FS file system, memory management improvement, and the removal for i386 support.

Linux 3.9 brings the following key changes (Sources H-Online and Phoronix):

File-system improvements:
- Btrfs has experimental RAID5/6 support and fsync performance improvements.
- EXT-4 bug fixes for corruption issue, and JBD2 journaling layer issue which affected performance.
- Various improvements for F2FS file-system.
Added ability to use SSDs as hard-disk cache.
Update the latest LZO compression implementation within the kernel. Decompression and compression performance has been massively improved and x86 and ARM targets.
Improved power management, including “lightweight suspend” (aka “suspend freeze”) mode.
Improved ARM SoC support
- Added Nvidia Tegra 4 support including support for Dalmore and Pluto development boards.
- Added Nvidia Tegra 3 Beaver Board support
- Kernel-based Virtual Machine (KVM) support for ARMv7 (Cortex A15 required)
Mainlining of Google’s Goldfish virtual CPU.
Initial ARC Linux support. See commit.
Added support for Imagination Meta ATP (Meta 1) and HTP (Meta 2)
Graphics drivers updates – Nouveau, the open-source reverse-engineered NVIDIA Linux graphics driver, is faster for some Linux OpenGL games. There’s also some Intel OpenGL performance changes.
Support for Intel 7000 Wi-Fi components supporting 802.11ac.
CONFIG_EXPERIMENTAL kernel configuration option has been removed

More details about Linux 3.9 will be available on Kernelnewbies.org (which is currently down).

Booting Linux in Less Than 1 Second in AllWinner A10 Devices? Yes! You Can!

April 22nd, 2013 cnxsoft 4 comments

threewater, a Chinese developer, has just posted a very interesting demo on linux-sunxi mailing list showing a device based on AllWinner A10 boot linux within 0.85s, and if you add a Qt app, the total time is just about 1.2s.

This appears to be a custom hardware (EM6000), but we do know it’s based on AllWinner A10, comes with 512 MB RAM, and 4GB NAND Flash. On the software side, the device runs kernel 3.4 from linux-sunxi, with a customized version of uboot, a squashfs rootfs, and a Qt 4.7.4 app showing a gauge. Both the rootfs (7MB) and the kernel (2MB) have been compressed with LZO. All that boots from NAND flash for optimal speed.

The 1.2 second time includes kernel + rootfs + app time, and the total time is a bit longer, but this is still impressive. Here’s the boot log:

[1.690000 1.690000] U-Boot SPL 2013.01-05984-g2120a27-dirty (Apr 17 2013 - 14:22:02)

[1.187000 0.012000] Please check your tslib installation!
[1.200000 0.013000] qt show

If you just boot to the command line, it’s even faster:

[1.770000 1.770000] U-Boot SPL 2013.01-g8a69ff9-dirty (Apr 22 2013 - 13:05:36)

[0.843000 0.008000] login[42]: root login on 'ttyS0'
[0.851000 0.008000] [root@(none) /root]#

This is not the first time, people have implemented ultra fast boot on ARM hardware, an example is a ~400ms boot on the Beagleboard, but it’s still nice to see what can be achieved thanks to developers’ communities such as linux-sunxi.

The complete details and/or binary files are not available at this time, but if you are interested in Linux fast boot, you may considering checking Adeneo Embedded presentation at ELCE 2012 who did something very similar on Freescale i.MX51 & i.MX 6Q hardware.
