A20-OLinuXino-LIME Revision H is now in stock. The OSHW Linux computer now support eMMC and can be produced with industrial grade temperature -40+85C

A20-OLinuXino-LIME now is at revision H. What is new?

  • We now support eMMC Flash
  • Ethernet PHY is changed from Realtek to Micrel/Microchip as latter can be purchased in both commercial and industrial grade
  • SPI Flash with hardware write protect is supported which allow board to boot from net.
  • Industrial version of LIME is available with T2 Allwinner with all components -40+85C operating temperature
  • EEPROM now contain unique MAC address , serial number and configuration info

We decided to drop the odd shape which was made specially to fit LIME in the Hammond plastic box, instead it range of Metal Boxes is available.

Latest image supports all new feature.

It’s confirmed T2 -40+85C ARM processor is pin to pin compatible with A20

T2

We assembled T2 on A20-OLinuXino-MICRO, A20-OLinuXino-LIME, A20-OLinuXino-LIME2 and A20-SOM and completed full functional tests, all peripherials on T2 works exactly same as A20 with same Linux images and setup, which confirms that T2 is just re-branded A20 with extended temperature range.

We wait now first volume order of T2 to arrive and we will add T2 industrial versions of ourA20-OLinuXino-MICRO,A20-OLinuXino-LIME,A20-OLinuXino-LIME2 and A20-SOM boards.

This will include T2 SOC, MT41K256M16HA-125IT:E DDR3 memories from Micron , Ethernet PHY all in industrial temperature range. For this purpose we moved in the newest revision of our boards from Realtek to Micrel/Microchip as latter has availability in both commercial and industrial temperature range, while Realtek parts are sold only in commercial 0-70C operating temperature. The price of the industrial version will be around EUR 10-15 more than commercial to cover the cost of the extended temperature parts.

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.

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.

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-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.

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

LIME2 get better now with eMMC Flash A20-OLinuXino-LIME2-eMMC

A20-OLinuXino-LIME2-eMMC

A20-OLinuXino-LIME2-eMMC was developed first for customer of ours, but after we saw the result we decided that it’s good to add it in our web shop.

What difference make eMMC instead of NAND Flash?

eMMC behaves like SD-card so no need for special drivers, you write on it as you write on SD-CARD, it’s faster than NAND Flash, and it’s more reliable.

The eMMC Flash we use is industrial grade -40+90C SLC Flash from Micron. All other functionality remains same. Note thatA20-OLinuXino-LIME2-eMMC is still not 100% industrial temperature grade, the DDR3 and Ethernet PHY are in commercial temperature grade (0-90C for the DDR3 and 0-70C for Ethernet PHY), we have industrial grade DDR3 and can build A20-OLinuXino-LIME2-eMMC with such memories,so the next step to complete industrial grade temperature board is to find proper industrial grade Ethernet PHY chip.
