New Debian 10 Buster images released for A20 and A64 boards and SOMs

buster

We have released Universal A20 and A64 images with Debian 10 Buster.

There are few known issues which we work on:

  • Certain types of eMMC memories might start in HS-200 mode instead of SDHS mode. This causes eMMC installation and boot problems.
  • HDMI always takes precendence over LCD. This is even if you have enabled a
    display manually (interrupted u-boot and executed “olinuxino monitor set XXX”).
  • Boards with 5.x eMMC chips are unable to boot directly from eMMC;
    this is caused by poor eMMC 5.x support in eGON BROM;
    this issue is not related to the Linux image
  • The board currently cannot store rootfs on usb driver. The init script
    starts before the usb subsystem initialization.
  • If the board has eMMC and SPI, it’s not possible to boot from SPI and rootfs
    on SATA. This is due to the fact that u-boot searches first the eMMC storage
    for boot scripts.
  • LCD-OLinuXino-15.6FHD is not fully supported.
  • The GT2005 camera module in A20-SOM-EVB and A20-SOM204-EVB is not working.

New release is preparing and will be updated by the end of the month.

 

 

New from our forum – experimental NixOS image for TERES DIY OSHW Laptop

Recent post from our forum explains how to build experimental NixOS image for TERES-I  – Do It Yourself, Environmental friendly, modular Open Source Hardware ARM Laptop.

Lime2-SD add on board for second SD card on A20-OLinuXino-LIME2

Lime2-SDa.jpg

Lime2-SD is small add on board which snaps on GPIO-1 connector and add second SD card to A20-OLinuxino-LIME2. It doesn’t interference with other parts on the board and do not increase the height.

Lime2-SD

Why we do this? Because this is an easy way to increase storage for Pioneer-FreedomBox-HSK . What we are preparing to offer soon is upgraded version of the Home Server Kit with 256GB storage made with 2 “disks” x 128GB micro SD cards. For these who already have Pioneer-FreedomBox-HSK they still can upgrade by ordering Lime2-SD .

Note that support in FreedomBox for Lime2-SD is not add, but you can try Lime2-SD with the current Armbian image for LIME2. To enable the Lime2-SD support you also have to add this dts overlay .

 

Writing applications for OLinuXino with GTK

GPIO

Many times I hear from customers – Linux has no good UI, it’s made for servers but we want to make apps with windows drop boxes, check boxes etc.

Recently we found Simon Long’s C GUI Programming book and made two “windows” examples for OLinuXino.

We recommend you first to download the book and read it then to look at the code we made and uploaded to GitHub.

In the README.TXT you will find step by step instructions how to install and configure GTK for OLinuXino.

Then you can try the code and modify for your need.

GPIO example allow you to read or write GPIO state to any of the GPIO connectors of OLinuXino.

I2C example will allow you to interface to any of our UEXT boards with I2C interface. The example we test with MOD-IO.

How to choose best LCD for your Linux computer? This is why we made LCD-OLinuXino selection guide

LCD10-METAL-FRAME-1

LCD-OLinuXino selection guide will help you to select best solution for your OLinuXino Linux SBC.

Inside we explain the different LCD connectors available in OLinuXino.

What LCD variants are available: 4.3″, 5″, 7″, 10.1″, 15.6″.

What signals are there when the interface is RGB or LVDS on the 40 pin connector.

How we implement plug and play capability with our latest Linux images and LCD driver boards, so you do not have to configure the LCDs, but they are recognized at boot time and all drivers configured.

What are the pro and cons and differences between resistive and capacitive touch screen technologies.

How to enable digital touch interface on A20 boards.

How to configure the software and drivers for the older LCD driver boards.

 

 

OLinuXino Open Source Hardware Single Board Linux Computers are now officially OSHWA certified

Ax0-OLinuXino-LIME-1

OLinuXino Open Source Hardware Linux Computers now are officially OSHWA certified. The first: A13-OLinuXino, A10-OLinuXino-LIME, A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO has their assigned OSHWA certification numbers, the others are to follow as the process takes time.

Searching the OSHWA directory only Beagle Bone and OLinuXino are officially certified.

Long Term OLinuXino supply – How it works?

Screenshot from 2019-05-16 14-50-39

We got question from customer of ours: “We are using your A20-OLinuXino in our product and I’ve heard that you are going to stop the production soon, is this true?”

Most of our customers are industrial machine producers and they need long term supply from their vendors. They do certification for their machines which cost a lot and they can’t afford to spend more money every year because the Linux module is not produced or changed. We already wrote several post on our blog that we supply our boards until there is demand for them and that we have long term supply agreement with Allwinner, but some people spread rumors and I have to write it and make it clear again: We will produce OLinuXino boards until there is demand. It’s even included in our GTC.

When back in 2014 I posted that we can supply OLinuXino forever many people were skeptical (well yes it is exaggerated 🙂 ) and wrote back – do not believe Chinese suppliers, they will let you down etc. etc.

Allwinner though is keeping their promise and we can buy all Allwinner SOCs we use without problem. Our volumes allow us to meet their MOQ.

For instance A13 SOC is very old and Allwinner discontinued it several years ago, it’s even not listed on their web as product, but we still keep buying it and producing A13 boards for our customers. We have also many customers which used our boards as template to make their own variants and now we supply them with A13 SOCs so they keep manufacturing them. You will not find A13 for sale anywhere even in China, but we are expecting next lot of 90Kpcs A13 to come from Allwinner in few weeks. Yes we have to order such quantities as Allwinner need 3 month to produce the SOCs from the order to shipment.

Many customers ask can you guarantee 10-15-20 years of supply? I doubt anyone in industry can see so long ahead. Allwinner is young company, founded September 2007, i.e. less 12 years old. Who knows what they will do after 20 years? We see that Western companies with much more history change owners every year and no one knows what the new owner will decide to do, so no one can give you 10-20 years prediction or will simply intentionally or unintentionally mislead you.

For A13 and A20 this agreement works well last 7 years. Both we at Olimex and Allwinner has no reason stop production, which brings money to both of us. We got visit from Allwinner sales manager in March this year and he said that they never though they can sell A13 and A20 for so long time. Most of other SOCs they sell target consumer market where lifetime is 1-2 years top.

Linux and Open Source Hardware works well for them and prolong their sales.
