Industrial grade -45+85C STMP1-SOM is almost completely routed and pin to pin compatible with A13-SOM

STMP1_SOM_bot

A13-SOM-256 and A13-SOM-512 are low cost Linux running System on Modules which are very popular but lack industrial grade operating temperature.

STM32MP1XXX series of SOC from ST is the first mass produced SOC which operates from -45 up to +125C by default, so we decided to design SOM module with STM32MP1XX SOC which to be pin to pin compatible with A13-SOM and offer same interfaces and signals so it could be drop in replacement for A13-SOM without need to re-design the complete product.

As you can see for STMP1-SOM we decided to put the SOC on opposite side of the connectors, this allow if necessary to add aluminum heatsink without interference with mainboard.

STMP1-SOM_TOP

Also we add AXP209 PMU which allow lower power operating modes and LiPo battery backup and operation on battery only which is missing in the original A13-SOM.

STMP1-SOM will be offered with three SOC choices STM32MP151, STM32MP153 and STM32MP157.

The prices will start from EUR 15 for the non industrial grade memory which are similar to A13-SOM and EUR 18 for the industrial grade -45+85C memory version.

We expect first STMP1-SOMs to be available in July 2020.

Full mainline Linux support will be available at http://images.olimex.com/

Olimage – Mainline Linux images building script for all of our OLinuXino and SOM boards

DEBIANubuntu_904

We work for more than 6 month on our own Linux building script and now we are ready with it’s initial release, which is now on GitHub .

Why do we need it? The number of our boards with all variant hit over 70 pcs when you add to them the different LCD combinations and other peripherials the support and test of these images became little hell. Our latest Armbian based image was released 3-4 months ago as we didn’t manage to properly test all board features in the newer images.

So we first made universal images for all our groups of boards (based on the SOC used) and EEPROM where we store info so uboot and kernel to may recognize the board and configure properly the parameters at boot time.

Then we decided to make one-for-all build script which will automatically build images with recent kernel and uboot automatically.

We had to leave Armbian as we wanted things to be more under our control and decision. Also we wanted everything to be 100% tested when released. Armbian official builds are not tested at hardware level other than to see board boots, so many boards are with peripheral conflicts and we had to apply our patched on Armbian anyway to adjust the images for our boards.

Our official images now are at http://images.olimex.com.

There is release folder where we have minimal and basic images for Debian and Ubuntu and testing folder where new uboot and kernel images will be built and kept until properly tested. For instance Ubuntu 20.04 LTS and kernel 5.6 images will be put there in the next couple of weeks.

The Olimage script and repositories are developed in our internal Gitlab and will be only push to Github when everything is properly tested and images moved to release folder. Also we push all our patches upstream.

With the current kernel and uboot users can easily generate any Linux distribution as it’s matter of building rootfs.

Moving to the next release would be possible simple by

sudo apt-get update && apt-get dist-upgrade

then re-boot of the board, so when we release new images all you have to do is to run the above commands and you will have the latest images.

For the moments the builder has A10, A13, A20, A64.

iMX233 and RK3188 SOCs are obsolete and not produced anymore by Rockchip and NXP, so they will be not included in the script. We still produce and sell these boards, but they will be discontinued when we use our existing SOC stock.

AM3352-SOM and AM3359-SOM will be included in the script, but we have no fixed date when, as we have to put earlier S3-OLinuXino and STMP1-OLinuXino-LIME2 which are with higher priority.

Open Source Hardware LIME2-SERVER user manual is uploaded and explains how to assembly and how to install Linux images of popular projects

LIME2-SERVERа

LIME2-SERVER is Linux server with only 2W consumption, A20-OLinuXino-LIME2 and option for HDD or SSD.

The server has bild-in LiPo battery which allow it to run for hours without external power supply, Gigabit Ethernet connection and power adapter 5V 2A.

Today we uploaded on GitHub the initial version of the user manual which explains how to assembly the boxes in case you didn’t bought it assembled.

Also basic instructions to use Ubuntu Bionic and Debian Buster images we provide.

KODI and NextCloud installation.

Additional info how to build and install Home Assistant, Yunohost, TOR server will be included in the next revision.

BAY-HDD/SDD is easy way to add external storage to LIME and LIME2, now Pioneer-FreedomBox-HSK can have 2000GB external storage in robust enclosure

LIME2-SERVER8

BAY-HDD-500GB, BAY-HDD-1000GB, BAY-HDD-2000GB and BAY-SSD-512GB are external disks with special bridge board to plug in A20-OLinuXino-LIME and A20-OLinuXino-LIME2 servers providing all necessary connections and power supply for external disk.

It’s plug and play recognizable by Pioneer-FreedomBox-HSK and adds significant amount of storage to the platform.

 

The A20 driver for HDMI audio is almost done!

kodi

UPDATE 20-01-2020: Now the A20 HDMI Audio driver patches are submitted  and KODI images with working HDMI Audio are on our ftp

We blogged few weeks ago about the KODI image done for A20 and A64 by our friends Dimitar Gamishev and Stefan Saraev.

A64 had everything working fine, but the A20 image had no HDMI audio, as there is no such driver in the mainline kernel. This of course made A20 not useful for media center.

We decided to try to solve this problem by ourselves by writing this missing driver and today we have success!

The audio driver for HDMI is working, but is still far from complete as we have to add channel management etc, but with our driver we can hear audio via the HDMI with A20!

We will complete and send the patches to mainline after our Christmas-New Year vacation, so somewhere in January the KODI image (and of course all Olimex official images) for A20 will be updated and will have HDMI audio too!

 

A20 and A64 OLinuXino now with Libre Elec and Kodi support!

libreelec

LibreELEC is small OS which has everything to run KODI on top of it. Thanks to Dimitar Gamishev and Stefan Saraev now A20 and A64 OLinuXino has support for it.

A20 has one annoying problem there is no HDMI audio as listed in Linux-Sunxi mainlining efforts.

A20-mainline

If someone is capable to do this and have time to spend would be great, as it seems nobody cares to use A20 as media player 🙂

On A64 everything works and HDMI has audio as well.

kodi

so KODI is running full featured:

movie

Both A20 and A64 decode up to 4K movies but of course can’t display  such resolutions.

Build scripts are on GitHub. Images will be add to our FTP.

 

New mainline Linux images with Kernel 5.3.8 for A13-OLinuXino and A13-SOM are uploaded

adni18_Linux_Christmas

A13-OLinuXino and A13-SOM got new mainline Linux images based on Kernel 5.3.8 on our ftp.

The two distributions we usually release are Ubuntu 18.04 LTS Bionic and Armbian/Debian buster next with build instructions and ready to burn to SD card images.

New IP Camera OSHW board in design RFC

img2

We started recently new design with Allwinner S3 SOC.

The board have these features:

  • Allwinner S3 Cortex-A7 running at 1.2Ghz
  • AXP209 PMU with Lipo charger and step-up for UPS
  • internal 1Gb DDR3 RAM at 1333Mhz
  • 100Mb Ethernet interface with PoE option
  • NAND/eMMC/SPI Flash on socket
  • WiFi / BT module with RTL8723BS
  • Audio In and Out
  • UEXT connector
  • Lipo battery connector
  • Configuration EEPROM
  • LCD connector for LCD-OLinuXino
  • MIPI camera connector with RPi pinout
  • CSI camera connector
  • Dimensions: 60 x 50 mm

img1

S3 SOC is on bottom so heatsink could be add if overheating due to the small PCB area.

img3

We want to build intelligent camera solution which can be powered by PoE and can work with both wired and wireless Ethernet connection.

We add MIPI camera connector with RPi pinout as there are plenty of cheap 5Mpix cameras available.

We also will provide CSI camera with 5-8Mpix separately.

Why we do this board? We want to have intelligent IP camera among our tools and we put features which are necessary to fit our potential projects. This board have also potential for Voice over IP , Video over IP, Security, Home remote monitoring etc.

Initial upload on GitHub is with our schematic and components put on PCB locations, routing is ahead, so we would like to hear your opinion.

Did we forgot something?

Can we do something differently or better?

Let us know what do you think.

STM32MP1-OLinuXino development update, we managed to build Ubuntu 18.04.LTS with Linux Kernel 5.3. Now we need your feedback on GPIOs

kit

One of the benefits to work with European SOC vendor and distributors – just few days after we show interest in the new STM32MP1 series of SOCs DHL come with one big carton where we got STM32MP151AAC and STM32MP157AAA3 samples plus the most comprehensive ST kit with all features of the high end STM32MP157AAA3. The credits go to EBV as we got these totally free of charge. The kit came with comprehensive documentation for both board, software support etc. In regard of customer friendliness Chinese SOC vendors has long way to go.

We needed one day to build our own Linux image as we didn’t like (no offense) the Yocto ST uses, so here is Ubuntu 18.04.LTS with Kernel 5.30 boot:

screen

Overall we have very positive vibes that STM32MP1 is good candidate for new industrial grade OLinuXino-LIME2!

The specs of the STM32MP1-OLinuXino-LIME2 we work now are:

  • STM32MP151AAC or STM32MP157AAA3 they are pin to pin compatible so one board will be used for both
  • 1GB DDR3L industrial grade memory -45+90C
  • Gigabit Ethernet with PoE plug-in option (*)
  • AXP209 PMU with LiPo charger and step-up so everything works even with no external power supply
  • two USB 2.0 high speed hosts
  • USB-OTG 2.0
  • HDMI+CEC
  • LIME2 board shape and same connector positions
  • replacing with CAN the SATA connector
  • micro SD-card
  • SPI/NAND/eMMC Flash on socket and different options(**)

(*) we love what Raspberry Pi did with their PoE hat, board which is working as normal, and have PoE functionality if PoE hat is attached. We intend to add such PoE feature to our other Allwinner boards too, but will take time to re-design them all.

(**) this is new experimental feature instead to keep many different LIME2 board versions which only differs the amount of flash on them. The Flash will be on plug in module, something which Odroid does for years and we do wonder why we didn’t do earlier, as now keeping so many versions of LIME, LIME2 and MICRO is killing our production manager and logistics :). If these Flash modules work as expected we will re-design our LIME, LIME2 and MICRO to use them also .

STM32MP1 series has some very unique features missing in Allwinner SOCs like:

  • 6× I2C up to 1 Mbit/s
  • 4× UART + 4× USART up to 12.5 Mbit/s, ISO7816, LIN, IrDA, SPI slave
  • 6× SPI 50 Mbit/s, 3 FD I2S audio class accuracy
  • 4× SAI stereo audio: I2S, PDM, SPDIF Tx
  • SPDIF Rx with 4 inputs
  • 8-14-bit camera interface up to 140 Mbyte/s
  • 2× ADCs with 16-bit max. resolution 3.6-4.5Msps
  • 2× 12-bit D/A converters 1 MHz

We will try to arrange GPIOs with similar functions so A20-LIME2 current customers to may exchange with STM32MP1-LIME2 if they want or to have second SOC choice, but we are open to listen to your tips and suggestions how to arrange the ADC/DAC signals and extra I2C, UARTS, SPIs on the GPIO1-GPIO4 connectors optimally.

STM32MP1 series has only one operating temperature range -45+125C.

Many people may think that on 650Mhz the Cortex-A7 cores are running slow, but this is because this SOC has to work reliable from -45 to +125C. All SOCs which run on extended temperature range run on lower speed clocks compared with same parts which run on commercial 0-70C. If you want to run your STM32MP1 board at home in non demanding apps, we are pretty sure you will be able to overclock it at much higher values and it will work, but when we talk industrial devices and reliable 24/7 operation the clocks are always announced with most conservative values.
