It’s a pleasant surprise to see our AM3352-SOM in High-End Audio product at M.O.C. Messegelände München

It was noticed by our friend and Audiophile Boris Ribov from Technical University in Plovdiv, who went to visit M.O.C. Messegelände München.

Our guess is AM3352-SOM is used as communication board there handling USB, Ethernet etc communication.

Sitara System On Modules expands with new processor AM3359 and SLC NAND Flash option

AM3352-SOM-EVB-1

We have more Sitara SOMs in stock:

  • AM3352-SOM with AM3352CZBZ100 running at 1Ghz
  • AM3352-SOM-IND with AM3352CZBZA100 running at 1Ghz (-40+85C)
  • AM3352-SOM-512-IND with 512MB SLC NAND Flash on board
  • AM3359-SOM-IND with AM3359CZBZA80 running at 800Mhz(-40+85C)
  • AM3359-SOM-512-IND with 512MB SLC NAND Flash on board

Sitara internal bootloader do not handle well big NAND Flash memories, so for the moment 512MB is what we can use with current design.

SOM204 version with eMMC will be available by the end of this year and it will allow up to 64GB eMMC Flash options.

 

A20-SOM204 and SOM204-EVB preliminary info is uploaded on our web

A20-SOM204-T

SOM204 is SODIMM form factor System-On-Module we are working for a while (actually from so long time ago that SOM204-EVB platform is made in Eagle which we dropped to use officially from quite some time ago).

The SODIMM connector has these signals:

  • Power supply: +5V, GND, LiPobattery, RTC_backup, Stepup-Output, Stepup-enable, USB+5V
  • Interfaces: Gigabit Ethernet, Megabit Ethernet, CAN, SATA, PCIe, USB2.0 HOST x2, USB-OTG, USB3.0 HOST, HSIC, UARTx3, SPIx2, I2Cx2, CSI, microSD, GPIOs with interrupts,
  • Display: HDMI, VGA
  • Audio: SPDIF, Line-in/out, Microphone, Headphone.

You can see complete SOM204 platform signals here.

The idea behind SOM204 is to make Universal interchangeable SOM with different performance and resources.

Our first SOM204 module is with A20 processor, it’s now in production and will be available for purchase next week.

The second SOM204 module is with A64, the third is with RK3328 which we expect to be ready for production around June. Next to follow is AM335X which will be ready by end of the year together with RK3399. The goal is to have 5 different modules by the end of the year.

A20-SOM204 comes with 1GB RAM, optional SPI Flash or eMMC Flash up to 64GB, two native Ethernets (this is the only A20 board with dual native Ethernets) Gigabit and Megabit, SATA and so on. The USB3.0 interface and PICe interfaces are not wired. On top on SOM204 platform LCD and additional GPIOs are exposed on FPC connectors:

A20-SOM204-B

The A20-SOM204 schematic is here.

A20-SOM204-EVB is evaluatuon board with A20-SOM204SOM204-EVB2

A20-SOM204 software is Armbian with mainline kernel and support for all SOM peripherials.

 

New Sitara AM3352-SOM-IND with industrial grade components work from -40C up to +85C

AM3352-SOM-1

Our popular AM3352-SOM module now is available in industrial temperature grade -40+85C under name AM3352-SOM-IND.

MT41K256M16HA-125IT:E memory used is with -40+95C operating temperature.

AM3352BZCZA100 processor used from Texas Instruments  is with -40+105C operating temperature.

AM3352-SOM-IND module can be evaluated with AM3352-SOM-EVB.

Debian Linux distribution is officially distributed, but recent patch add support for AM3352-SOM in Beaglebone kernel

World smallest System-On-Module with A20M released, dual instruction set x86 and ARM v7, can run any code in and OS!

SOM

What you see above is our first prototype of A20-SOM-NANO with only 30×15 mm this is the smallest A20 System On Module running Linux, Windows, Android and DR-DOS 3.3!

It’s based on the newly released A20M processor which is dual architecture and can run with ARM and x86 instruction set. This makes possible to use all existing software which runs on ARM and x86 platforms, even the old DOS programs can run on Linux and Window bash command prompt without any modification.

The best of all is that A20M is pin to pin compatible with A20 but with balls on 0.4 mm step and dimensions only 7×7 mm.

Allwinner specially designed this processor for our new module so you will not be able to buy it through their distribution channels.

These modules are assembling now and will be in stock next week!

 

A31-SOM update

a31-som

About year ago we posted on this blog about our work on A31 SOM module, a lot of time passed away so we would like to make clear statement about it’s status.

A31 SOM hardware was complete long time ago, but we found lot of bugs in A31 during the software development. Lot of things do not work as expected and the chip have overall poor performance. The video is with PowerVR which means there will be no Linux acceleration forever. All you will got running on it with hardware acceleration is Kernel 3.4 with Android. Memory do not work reliable above 200Mhz clock which is terrible performance. While we have hesitated if we have to put more effort on this chip we got notice from Allwinner that they discontinue A31 and A31s production which ended our hesitation.

A31 has very short life, Tom Cubie shared on IRC before while that Allwinner internally hate this chip with all it’s bugs too 🙂 so I guess Allwinner also got relieve to get rid of it.

Leasons learned, we move forward 🙂

RK3188-SOM, RK3188-SOM-4GB and RK3188-SOM-EVB are in stock now!

rk3188-som-evb

RK3188-SOM and RK3188-SOM-4GB system on modules are now in stock, these modules have same size as A20-SOM 81.28 x 55.88 mm and use same 0.05″ connectors, well they are not exchangeable though.

RK3188 is quad core, Cortex-A9 running at 1.6GHz. What does this means? Comparing to A20 you can expect everything to run about 10 times faster.

As power requirements, it takes more power than A20 obviously you pay for the performance and the higher clock rates.

For these who want to make their own board we made RK3188-SOM-EVB template with:

  • HDMI
  • 100Mb Ethernet
  • x4 USB hosts
  • USB-OTG
  • RTC clock and backup battery
  • +6-16VDC power supply
  • LCD connector where you can connect LCD-OLinuXino-XX LCDs
  • 2x 40 pin 0.1″ step GPIO connectors

RK3188-SOM starts from EUR 35 for 1000 pcs and it’s probably least expensive quad core Cortex-A9 1.6Ghz module on the market, the RK3188-SOM-4GB starts from EUR 40 / 1000 pcs.

The evaluation board RK3188-SOM-EVB cost EUR 70
