New univeral A20 image released which works with all our A20 boards and auto detect and configure on boot

d6ndarl

We are releasing universal A20 Linux image which will boot and work on all our A20 boards:

The image is based on Armbian with modifications necessary to support OLinuXino specific features.

There are two image releases – Ubuntu Bionic Desktop image which is the recommended image for beginners or when you want to evaluate the board’s hardware fully – it has good HDMI, audio support and Debian Stretch Server image which contains no binary blobs but is headless and has poor video and audio support.

Currently, our latest Ubuntu Bionic A20 image uses kernel 4.19.10, or to be more specific:

root@olinuxino:~# uname -a
Linux olinuxino 4.19.10-sunxi #5.65 SMP Tue Dec 18 14:19:16 EET 2018 armv7l armv7l armv7l GNU/Linu

Our Armbian Ubuntu Bionic image can be downloaded from FTP or Torrent.

Our Armbian Debian Stretch image can be download from FTP or Torrent.

Username is according to Armbian documentation: root and password: 1234

Since we have a large array of A20 boards and numerous variants there is auto-detection enabled in the image. Information about the model of the board is stored in the EEPROM of each A20 board that had been recently manufactured and this information is used by the new images to load the proper configuration. The EEPROM contents are described here.

The images can be used with boards from early revisions which has no EEPROM or has EEPROM with wrong content after one time set up of the EEPROM during in the first u-boot of the new image. If you have trouble booting interrupt u-boot by pressing space and type “olinuxino”. An example configuration for manually setting the EEPROM of A20-OLinuXino-LIME-e16Gs16MB hardware revision K is given at the end of the post.

The new images have support for both legacy resistive and new capacitive/resistive touch displays with auto detection feature (please bear with us they are not released yet on the web as we test them). The newer versions of the displays has suffix -CTS for capacitive touch screen and -RTS for resistive touch screen and are offered in 5″, 7″ and 10″ size with different resolutions. These displays are automatically detected by boot and drivers properly configured for them. If the LCDs are not detected HDMI output is only enabled and the image can be configured one time at first boot manually as described in this wiki article.

Please note that mainline Kernel now do not support NAND Flash, so if you wish to boot from the flash memory, consider either using the legacy 3.4.xx images which are still available or switch to A20 boards with eMMC. The eMMC boot is supported via armbian-config (nand-sata-install). Due to lack of reliable eMMC 5.X support by Allwonner boot0 and for future compatibility we are adding 16MB SPI flash for all A20 boards with eMMC, this way the board first boots from the SPI then continue to eMMC with properly set configuration. Allwinner Boot0 can’t handle correctly eMMC 5.X and sometime boot sometimes do not boot, as this is binary blob inside SOC there is nothing we can do than to use SPI boot to fix eMMC boot parameters.

Build instructions for the new images can be found here.

SPECTRE and MELTDOWN attacks and OLinuXino and SOMs

meltdown-and-spectre-vulnerability

The #spectre and #meltdown attacks were subject to great concerns in the last weeks.

Eben Upton made brilliant explanation of how and why they work in his blog post.

There is already project on Github which can be used to test if your ARM AArch64 processor is vulnerable to such attacks.

As Cortex-A7 and Cortex-A53 are not affected of these attacks this means all our boards with A20, A33, A64 processors are immune.

For A10, A13, AM335X (Cortex-A8), RK3188 (Cortex-A9) we need to do some further investigation.

More than 300 pcs A20-OLinuXino-MICRO work hard 24/7 in Traffic light controllers in Moscow

IMG_20171027_142604

We got nice e-mail from Andrey Taranov Head of RnD of Voice-Link JSC, Moscow, Russia to let us know that for the last 3 years more than 300 traffic light controllers are build with A20-OLinuXino-MICRO and work in the field in Moscow.

“They works hard in tough mode, 24/7 and shows good stability. We found your product well done, stable, and we glad to have partners, as you, and plan to cooperate in the future.”

Their product looks solid and impressive.

A64-OLinuXino Open Source Hardware board with 64-bit Cortex-A53 processor is in released

A64-OLinuXino-

A64-OLinuXino-22

A64-OLinuXino OSHW board is now released. Current revision is Rev.C.

Features are:

  • A64 Cortex-A53 64-bit SoC from Allwinner
  • AXP803 PMU with Lipo charger and step-up
  • 1 or 2GB or DDR3L @672 Mhz
  • 0 / 4 or 16GB of industrial grade eMMC
  • SPI Flash in SO8 package with hardware WP (not assembled)
  • USB-OTG and USB-HOST
  • HSIC connector (not assembled)
  • Gigabit Ethernet
  • BLE/WiFi module
  • HDMI and MIPI display connectors
  • microSD card
  • Debug console serial connector
  • Audio In and Out
  • LCD display connector
  • GPIO 40 pin connector (not assembled)
  • UEXT connector (not assembled)
  • 5V power jack
  • Dimensions: 90×62.5 mm

For the moment we have three models:

  • 1G0G with 1GB RAM, no Flash, no WiFi/BLE
  • 1G4GW with 1GB RAM, 4GB eMMC and WiFi/BLE
  • 2G16G-IND with 2GB RAM, 16GB eMMC with industrial grade components -40+85C

The optional connectors and SPI Flash etc may be assembled upon request for small fee.

A20-OLINUXINO-MICRO now available also in Industrial temperature grade -45+85C

A20-OLINUXINO-MICRO-EMMC-3

We are selling for some time already A20-OLinuXino-MICRO Rev.J where few things were improved:

  1. We changed the LAN PHY from Realtek to Microchip as latter is more reliable supplier for both commercial and industrial temperature components, we searched desperately Realtek PHY in industrial temperature grade but without success.
  2. We extended the input working voltage from 6-16VDC to 8-24VDC
  3. We changed the NAND Flash to eMMC (but old NAND style flash is still possible to assembly)

The Ethernet PHY change requires new patches on the Uboot and Linux images which are already uploaded.

A20-OLinuXino-LIME2 now with PCB revision G

a20-olinuxino-lime2

A20-OLinuXino-LIME2 now is assembling on same PCB Revision G as A20-OLinuXino-LIME2-eMMC.

What are the improvement:

  • Ethernet PHY is changed to RTL8211E replacing the obsolete RTL8211CL no need for kernel patches;
  • we drop the odd shape which was necessary to fit LIME2 in the plastic box as we now have range of metal boxes;
  • the four mount holes now have grounding for better contact with chassis;

Meantime we silently work on further improvement for next revision (to be released March 2017):

  • adding SPI boot Flash;
  • replacing RTL8211E to industrial grade PHY, so the board can be produced completely in -40+85C operating temperature;

 

Pre-Christmas Crazy times – Expansion of production capacity with three new Samsung machines

christmas-balls1

Probably many of you wonder why we are so silent recent months and nothing new is posting on the blog. The reason is quite casual – we are overwhelmed with work!

Starting from September something odd happens. Our OLinuXino customers went in crazy mode and we start getting almost twice more orders than usual. All who have been dealing with production know that to double capacity needs time.

This is the reason for the delay with iCE40HX8K-EVB, A64-OLinuXino, TERES release – there is simple no free window on the SMT assembly machines and testers to may run them, the machines are busy with OLinuXino and SOM assembly.

The small orders are shipping on time i.e. in 1-3 working days, but all bigger OLinuXino and SOM orders for 50+ boards are now shipped with a bit of delay as we have quite backlog for these boards.

We apologize to all our established customers which do wonder why the orders which we usually shipped to them in 1 week before, now are shipped with delay of 3-4 weeks.

We assure you that we do everything humanly possible to ship all orders ASAP.

To add little more crazyness the three new Samsung machines arrived two weeks ago. We wanted to build new space for them and working more than year on this, but the lazy and ignorant Bulgarian administration still didn’t issued us permit to start building, so we have to install them in the old building where we run out of space.

One SM471 and  two SM482 with printers, loaders, unloaders, conveyors, packed in 20 wooden boxes were unloaded from the containers:

20161118_102435

Immediately we start to break walls, extend doors, and other funny things so the big machines may enter the building.

20161126_085319

20161126_085332

20161127_075039

We did same 1 year ago when our first Samsung came, but shortsighted decided to rebuild the walls with intention the new machines to be installed in the new building, without taking into account how long and difficult the building permit is to get in Bulgaria.

Now the three machines are installed and testing, but as you guess they will not run alone, so we will need new employees to train.

New Year – new luck we say here, I hope things will go back from crazy to normal mode in January!

EDIT:

Some words about the machines SM471 is the Samsung fastest and greatest from SM series. It has two heads with 10 nozzles each and dual rail conveyor which allow two different boards to be assembled at same time. With maximal performance 75000 csp (which you never reach on real boards). The machine can place down to 01005 components which are with size 0.4 x 0.2 mm (400 x 200 microns)!

SM482 is flexible mounter which can place both small and big components, we already have one such machine and it performs very well. The listed maximal speed is 28000 cps.

Each SM482 machine comes with full set of 8, 12, 16, 24, 32 mm feeders and tray changer which can hold up to 80 trays with components.

Both SM471 and SM482 support the new splice-less tape feeders which can be load even with component stripes without need to have initial empty cells on the tapes.
