Olimex.com server maintenance

maint

We have scheduled maintenance for olimex.com server at 2:00 PM PST on Friday, May 24th, 2019. So our site will be down for couple of hours.

We apologize for the inconvenience.

Bye Bye G+, Hello Mastodon (Fosstodon.org)

mastodon

G+ is closing our account from April 2nd, we have no idea if they will keep our posts or will delete them, anyway there are always copies in Twitter and Facebook.

As many people do not want to use Twitter and Facebook for their own reasons, we searched for G+ replacement and it seems that Mastodon is the perfect choice.

So we are replacing now G+ with Mastodon and you can read our posts at https://fosstodon.org/@olimex

Rockchip is releasing low power SOC with NPU targeting deep learning.

1808

We are hacking cheap Chinese soldering robot aiming to make it usable with camera fiducials and solder joint inspection. I shared some info on Hackaday 2018 Belgrade conference.

As we want to make the robot easy to use we are looking around for capable SOC with Deep Learning capability. It seems the only embedded available solution now is nVidia.

Allwinner has put in their V5 SOC info about AI and Trensorflow support, but looking at info for the only available board on the market it looks just statement and no actual implementation.

The AI they advertise looks more like OpenCV / Tensorflow lite libraries using the V5 GPUs, but not real NPU.

Rockchip seems to be this time a little bit ahead of Allwinner and has released RK1808 and RK3399pro SOCs.

Some info also start to appear in their rockchip-linux repositories.

We got RK1808 brief datasheet and here are the SOC internals:

  • Dual core Cortex-A35
  • Internal 2MB SRAM
  • DDR 32-bit data width, 2 ranks max 2GB of DDR3/DDR3L/LPDDR3/LPDDR3L -1600
  • Neural Process Unit with 512KB internal buffer and Support for: max 1920 Int8, max 192 Int16 and max 64 FP16 MAC operations per cycle
  • eMMC 4.5 1-4-8 bit max 150MB/s
  • SD/MMC support
  • SPI Flash x1-4-8 data
  • video encoder/decoder up to 1080p
  • video input DPI 8-10-12-16 bit up to 150MB/s
  • camera input MIPI CSI up to 4 data lane, 2.0Gbps, MIPI-HS, MIPI-LP
  • LCD RGB 8/8/8 up to 1280×800@60fps
  • MIPI DSI 1920×1080 up to 4 data lane, 2.0GbpsA
  • Audio I2S
  • Gigabit Ethernet
  • USB2.0 HOST/OTG
  • USB3.0 5Gbps
  • PCIe 1/2 links with 2.5Gbps per link
  • SPI, I2C, UART
  • x4 10bit SAR ADC 1Msps
  • -40+125C operating temperature, targeting automotive and industrial vision apps

This chip is definitely not hobby friendly with FCCSP 420 0.3mm balls spaced at 0.5/0.35mm!

Price info is not available yet. First evaluation boards will be ready end of March 2019. Rockchip will sell SDK with the NPU API also at unknown yet price.

Rockchip also upgraded their RK3399 including inside RK1808 and naming it RK3399Pro.
They keep the same RK3399 ball layout, so people who already made RK3399 boards can upgrade with RK3399Pro without changing lot on their PCB layout.

How they do it? They bond RK1808 in the same package and connect RK3399 with RK1808 via USB3.0 this is why RK3399Pro has NO externally available USB3.0:

How they will manage power dissipation when they put together two quite power hungry chips is yet to be seen. RK3399 alone requires quite big heatsink as it dissipates up to 20W when the Cortex-A72 cores are running.

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.

An example configuration for manually setting the EEPROM of A20-OLinuXino-LIME-e16GB hardware revision K is given below:
