opencv

OpenCV 4.0 is officially announced.

What’s new?

  • OpenCV is now C++11 library and requires C++11-compliant compiler.
  • Most of C APIs are removed
  • dnn (deep neural networking) module includes experimental Vulcan backend for platforms missing OpenGL
  • QR code detector and reading is add to objdetect module

You can see all in the OpenCV change log

Our Summer Vacation is approaching!

summer.jpg

Our Summer vacation is from August 6th to August 17th. Please note that during this period our web store will work and you can place your orders, but they will be processed / shipped when we are back.

Orders which are placed in Friday August 3rd up to 12.00 our local time has great chances to be shipped same day, but if you really need something shipped before our vacation please do not count on last working day before our vacation to order it.

Allwinner released T2 SOC working -40+85C targeting automotive entertainment, it’s re-branded A20 with expanded operating temperature

T2

Allwinner released recently their T2 SOC targeting automotive entertainment panels.
Looking at the specs we saw that it suspiciously looks like A20.

t2-blk

This is not the first time Allwinner releases their old silicons under new names like A13-R8, A33-R16, R40-T3 etc.  I personally find this quite confusing.

We got some T2 samples and now assembly A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO and A20-SOM with them to test for hardware and software compatibility.
Once we are sure everything works OK will release T2-OLinuXino boards which will be with industrial temperature grade -40+85C for all components on the boards.

T2-abs

To this moment all our A20-XXX-IND boards has components for or exceeding -45+85C, but A20 SOC was specified -20+70C.

New Universal System On Module in SO-DIMM 204 pin form factor

SOM204-EVB

We have now several SOMs for A13, A20, AM3352, RK3188.

Each of them with different layout and pinouts as our initial intention was to expose all possible features of every processor.

The experience we got from selling the SOMs for the past 5 years is that 99% of customers do not need all specific interfaces, but few common interfaces.
For instance very few customer need 12 UARTs and 6 I2C in their design, but almost all need Ethernet, HDMI, SATA etc.

Another important point is that soon or later the project they working on scale up and they need more memory or more processor power and with the current SOMs they have no option but redesign.

Every big customer need longevity assurance. They do not want to change their design every couple of years when the SOC manufacturer obsolete their processors, they do not want to re-design every 6 month when new processor with 4-6-8-10-12-24 cores appear to the market with preliminary buggy software support.

So with the years one another idea evolved – we should try to make one universal SOM layout with known interfaces on known pinout, so if customer need more memory he just switch to SOM with same pinout but more memory, if need more power he switch to SOM with same pinout but more powerful SOC.

We have experience with Allwinner, Rockchip and TI, so we considered these processors as potential new SOM SOCs:

A20, A64, RK3399, AM335X

After long discussions we decided that the universal SOM should have these signals:

  • USB-OTG
  • USB-HOST1
  • USB-HOST2
  • HSIC
  • USB3
  • PCIe
  • Ethernet1 Megabit/Gigabit
  • Ethernet2 Megabit/Gigabit
  • WiFi+BLE
  • SATA
  • SD-CARD
  • CAN
  • IR
  • CSI
  • HDMI
  • VGA
  • Audio In
  • Audio Out
  • SPDIF
  • UEXT1 -> SPI1, I2C1, UART1
  • UEXT2 -> SPI2, I2C2, UART2

     

The first SOM204 we made is obviously for A20.

Here are the schematics of A20-SOM204 and SOM204-EVB.

Here is our A20-SOM204 prototype:

A20-SOM204

Features are: 1GB RAM, 4/8/16/32/64GB eMMC Flash, Gigabit Ethernet interface, 2K EEPROM,
Optional features not assembled by default: SPI Flash with hardware WP, Second Megabit Ethernet.

With this SOM we tested A20 with two Ethernet interfaces: one Gigabit and one Megabit working together. The practice prove A20 can have two separate working Ethernets, but there is one issue both share same clock, so if the both Ethernet works together they can be only Megabit.

The second SOM204 module we work on is with A64.
The features are 2GB RAM, 4/8/16/32/64GB eMMC, Gigabit Ethernet interface, 2K EEPROM
Optional features not assembled by default: SPI Flash with hardware WP, Second Gigabit Ethernet (USB-Gigabit), SATA (USB-SATA), CAN.

The third SOM204 module we work on is with RK3399.
The features are 4GB RAM, 4/8/16/32/64GB eMMC, Gigabit Ethernet, PCIe, USB3, 2K EEPROM
Optional features not assembled by default: SPI Flash with hardware WP, Second Gigabit Ehternet (USB-Gigabit), SATA (USB-SATA), CAN.

A20-SOM204 and SOM204-EVB will be for sale in November. Prices will be comparable to existing A20-SOM A20-SOM-EVB.

A20-SOM204 is separate product and not meant to replacement A20-SOM neigher we have intentions to discontinue A20-SOM. Both products will be active and in production.

Software support for all SOM204 modules will include Android and Linux.

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;

 

Microsoft licensing corruption scandal in Romania has ended on October 3rd

sandu-cocos-dumitru-stefan

This scandal covers buying Microsoft licensees for Romanian administration from 2004 to 2012 for total 228 millions USD.

During the investigation was found that more than 100 people, former ministers, mayor of Bucuresti and businessman are involved in this corruption scandal and more than 20 millions euro are paid as bribes.
The Romanian court ruled in March 2016 with sentences for 8 years of prison and 9 millions euro of asset forfeiture for the 4 persons on the picture.
These sentences were appealed and October 3rd the High Court of Cassation and Justice (HCCJ) confirmed the guilt and increased the sentences to 14 years in prison and 17 millions of euro of asset forfeiture for these same persons.

I have nothing to add but my admiration for the working Romanian Judiciary.

Bulgaria and Romania joined EU back in 2007 together and while Romanian people has will to change their future, the things in Bulgaria has very little improvements. In Romania there are near hundred of corrupted politics and public administrators in prison, in Bulgaria there are none. Supreme court in Bulgaria is overwhelmed with files, as everyone appeal his case for every small disputes up to the highest level. They have files which they have no capacity to review for next few years. So effectively there is no working Judiciary in Bulgaria. Тo judge someone here is just waste of money and time.

Bulgarian government spent almost 60 million of euro for Microsoft licensees from 2007 to 2011 and the “tender” winner is always one and same company.  I already posted about my wondering why such amount is spent for something with free alternative. Another question is why administration spends money for platform with 99% of all viruses existing and which is tool for US agencies to spy all around the world?

The information about Romanian corruption scandal was taken from here . I used Google translator so some numbers may be inaccurate 🙂
