A33-OLinuXino OSHW Quad Core Linux SBC prototypes ready for test

A33-OLinuXino-top

We just assembled our A33-OLinuXino prototypes, these have PMU and should not overheat so badly as H3.

A33-OLinuXino-bottom

The advantage to have PMU is also that it have LiPo charger and can run from LiPo battery.

The features are:

  • A33 Quad core Cortex-A7 SoC
  • AXP223 PMU
  • 1/2GB RAM
  • optional 4GB NAND Flash
  • Audion Input
  • Audio Output
  • CSI/DSI connector
  • 40 pin LCD connector for LCD-OLinuXino-XX LCD modules
  • USB-OTG
  • GPIO 40 pin connector

Both H3 and A33 support dual CS DDR memories, this means they can work with the new 8Gb DDR3 ram chips which have two CS lines and H3-OLinuXino and A33-OLinuXino could have 1GB or 2GB RAM as option.

A33 have no Ethernet and HDMI, would be good for handheld video/audio processing devices.

The next revision of H3 and A33 OLinuXino will have eMMC option too.

 

EDIT: 18.00 o’clock update A33-OLinuXino is booting and working fine. As we expected although with same Quad Core Cortex-A7 it do not overheats at all compared to H3. Something is really broken in the H3 Linux clock/power configuration!!!

Debian 8 (Jessie) is finally released for OLinuXino boards

debian_logo

Hurray! We finally managed to move from Debian 7  Wheezy to Debian 8 (Jessie)!

The new images use Kernel 3.4.103+ which is rather old, but have all video and graphics accelerations.

The boards that get the update are: A20-OLinuXino-MICRO; A20-OLinuXino-LIME; A20-OLinuXino-LIME2; A20-SOM (and their respective 4GB versions).

Links to the torrent files with the images are already available at the respective wiki articles of the boards.

What took us so long? Have look at our boards there are tons of peripherals and different LCDs, USB dongles, BT etc etc peripherials we had to test one by one to make sure EVERYTHING works, and when we see mistake we have to re-build the images and start from scratch again, this took us weeks. As you can see we still even didn’t do this for A13 and A10 boards we have as the process is really long and bumpy.

What’s new beside the move to the higher version of Debian? We gain some experience, made the images smaller, also now there is OPTION to install the images directly to the NAND Flash!

All you have to do is to run “nandistall” script and wait for the image to transfer from the microSD card to the NAND memory.

To move to the new Debian all you have to do it to download  the archive containing the image via the torrent from the wiki; then to extract the archive and prepare your microSD card with it. Note: the images are about ~2GB of size after extraction, but you can use bigger SD card as well. We decided to prepare the official images with lower user space in order to speed up the download and extraction time and to lower the time it takes to transfer the image to a microSD card. It is recommended to re-size the user space in order to use all space on your microSD. In the root directory execute the resize_sd.sh script as follows:

# ./resize_sd.sh /dev/mmcblk0 2

The build instructions and all required files are published in GitHub.

For more practical advice and basic starting point for the new image refer to this document.

Note that it is completely fine to continue using the previous Debian 7 (Wheezy) images if you don’t have some particular reason to switch to Debian 8.

Looking forward to your comments and feedback about the new images.

needless to mention this window button will become Tux 😀

 

Devuan Jessie for OLinuXino images

devuan

Devuan is Debian fork to get rid of so much disputed SystemD used in the newer version of Debian.

We were nice surprised to see that there are pre-built images for Devuan Jessie for A10-OLinuXino-LIME, A20-OLinuXino-LIME, A20-OLinuXino-MICRO and A20-OLinuXino-LIME2 in the file repository: http://files.devuan.org/

So now you have this option to run on OLinuXino!

A10, A20 OLinuXino LIME and LIME2 are officially supported in Debian 8.0 Jessie

Debian 8.0 Jessie now supports many Allwinner boards including A10-OLinuXino-LIME, A20-OLinuXino-MICRO, A20-OLinuXino-LIME and A20-OLinuXino-LIME2!

more info you can find on https://wiki.debian.org/InstallingDebianOn/Allwinner

 

Another interesting article for using mainline Linux uboot and kernel you can read here

Video and Audio Streaming from A20SOM-EVB using crtmpserver

A20-SOM-EVB-2

Our A20-SOM-EVB had camera support only in Android for a long time. Now we got e-mail from Ariee Dzig who says:

I created IP Camera using your A20SOM-EVB.
Here you can find the tutorial .

 

We try this tutorial and it works great! Now we prepare new Linux images for A20-SOM-EVB which to include the hardware encoding support for the camera!

Alternative Linux images for LIME and LIME2

A20-OLinuXino-LIME2-1

Igor Pecovnik has created optimized Debian image for Cubie board named Cubian, he asked for sample board and we sent him LIME2 so few days after he received the board he generated optimized Debian image for LIME2, you can see the instructions and images on his blog: http://www.igorpecovnik.com/2014/11/18/olimex-lime-debian-sd-image/

A10-OLinuXino-LIME-1

Remy van Elst did minimal Debian 7 for A10-OLinuxino-LIME https://raymii.org/s/articles/Olimex_A10-OLinuXino-LIME_minimal_debian_7_image.html
