May 2021 production delays and updates!

Everything is moving extra slowly this year.

On top of the Semiconductor shortages, now PCB factories also experience lack of raw materials and delay the production times more than double.

This is the reason our plans to release S3-OLinuXino, RK3328-SOM, STMP15x-OLinuXino-LIME2 and STM32MP15X-SOM to produced with delay.

At least we got the STMP15x-SOM and STMP1(A13)-EVB blank PCBs and by the end of next week they will be ready to order.

We used the time to update the product page with schematics and user manual.

Production updates for S3-OLinuXino, RK3328-SOM and STMP15x-OLinuXino-LIME2 will follow!

New Quad Core Cortex-A53 System-On-Module supports DDR3/DDR3L/DDR4 memories from 1 up to 4GB

Allwinner plans to release Linux capable RISC-V SOC this year

Searching for more info about their new H313 SOC I found old news from August 2020, where Allwinner announce the development of AP SOC with RISC-V and praising Open Source Hardware and the open ISA of RISC-V.

They say in this announcement that they will have AP (application processor) SOC with RISC-V in 2021!

There is lot of development around RISC-V in the last years. Espressif have their ESP32-C3 which is with RISC-V SOC, but it can’t run Linux as has not enough memory and video. We still can’t see affordable silicon capable to run Linux.

There is announcement for BeagleBoneV but still not in production and at quite higher price compared to ARM boards on the market.

Allwinner is known to be able to design and produce low cost SOCs. Let’s hope the semiconductor crisis caused by Covid19 will not delay their plans.

So is the year 2021 when we will see $35 Linux running boards with RISC-V?

I’m crossing fingers!

As soon as we can get our hands to these SOC we will make OSHW OLinuXino with it!

OSHW design and affordable SOC will lead to affordable boards and boost of the software development of RISC-V too.

To the best of our knowledge there is no Open Source Board so far which to be so complex and advanced.

Now we are running the first prototypes and crossing fingers everything to work 🙂

With the current state of the semiconductor industry production will not be possible to be run soon.

Linux support will need attention as NXP has no mainline Linux for this SOC, but only Yocto build for old kernel (4.14.98_2.3.3).

If there are people with experience and interest in this SOC we may share one of the first samples we build, so they can help on the Linux support.

The schematic of IMX8QM-TUKHLA Revision A is uploaded for review on out ftp.

S3-OLinuXino Open Source Hardware Linux dual camera board status uppdate April 2021

S3-OLinuXino is small open source hardware Linux computer with Ethernet, dual camera interface, running mainline uboot and Linux Kernel 5.12.

Our hardware went through few iterations, but last Revision.C now is in production and we will have it for sale on our web at the end of the April.

This board has small PoE plug-on top module which adds PoE functionality, so the whole setup board + cameras can be powered via Ethernet.

The camera connectors are made compatible with OV2640 2Mpix camera and Raspberry Pi Camera.

S3-OLinuXino has LCD connector where LCD-OLinuXino displays can be connected.

WiFi/BT module adds wireless functionality.

STMP157-SOM-512-IND industrial grade system on module status update April 2021

STMP157-SOM-512 is functional drop in replacement for A13-SOM-512 and have exactly the same features, but is industrial grade -40+85C.

All connectors have same signals on the both boards:

For STMP157-SOM-512 we made special STMP1(A13)-SOM-EVB:

With this board all SOM features can be explored:

  • two USB High Speed Hosts
  • one USB-OTG
  • WiFi/BT module with PCB antenna and option for external antenna
  • 100MB Ethernet
  • Flash connector for attaching SPI, NAND, eMMC Flash modules
  • Audio input, output
  • UEXT connector
  • LCD connector for LCD-OLinuXino-XX
  • GPIO connector

Needless to say the EVB works with A13-SOM-512 also.

Mainline uboot and Linux Kernal 5.12 with support for all peripherals is available.

STMP157-SOM-512 and STMP1(A13)SOM-EVB boards are now in production and will be on the web for sale by the end of April.

STMP157-OLinuXino-LIME2-IND status update April 2021

The last issues with STM32MP1 mainline Linux kernel support were resolved and now we run STMP157-OLinuXino-LIME2 in production!

Revision B fixes all hardware issues in the initial prototype. STMP157-OLINUXINO-LIME2 is complete analog of A20-OLinuXino-LIME2 which is one of our best selling Allwinner board.

Mainline uboot and Linux kernel 5.12 images are available with all periperials working.

We will have STMP157-OLINUXINO-LIME2 on our web for sale by the end of April.

This is also our first board with Ethernet supporting Precise Time Protocol and Time Sensitive Networking implemented.

IEEE 1588 Precision Time Protocol (PTP) is implemented for the industrial grade Open Source Hardware Linux computer STMP1-OLinuXino-LIME2

The Time Sensitive Networking (TSN) is for real-time communication with hard, non-negotiable time boundaries for end-to-end transmission latencies.

The main use of TSN is for industrial machine controllers, robots etc.

For this purpose all devices in this network need to have a common time reference and therefore, need to synchronize their clocks among each other. Only through synchronized clocks, it is possible for all network devices to operate in unison and execute the required operation at exactly the required point in time.

The time in TSN networks is usually distributed from one central time source directly through the network itself using the IEEE 1588 Precision Time Protocol, which utilizes Ethernet frames to distribute time synchronization information.

Linutronix helped to implement IEEE 1588 PTP on STMP1-OLinuXino-LIME2.

For Uboot changes Olimex Uboot was used as base. The Kernel patch is sent upstream and can be seen on the mailing list

https://lore.kernel.org/linux-devicetree/20210316080644.19809-1-kurt@linutronix.de/

We also apply these patches in our next STMP1 Linux images release.

The results is correctly working PTP:

# ptp4l -H -2 -i eth0 --tx_timestamp_timeout=40 -f /etc/gPTP.cfg -m
|ptp4l[1434.665]: rms    5 max   13 freq  -1069 +/-   7 delay   325 +/-   0
|ptp4l[1435.666]: rms    8 max   16 freq  -1068 +/-  11 delay   325 +/-   0
|ptp4l[1436.667]: rms   10 max   19 freq  -1060 +/-  12 delay   324 +/-   0
|ptp4l[1437.668]: rms    8 max   17 freq  -1055 +/-  10 delay   322 +/-   0
|ptp4l[1438.668]: rms    6 max    9 freq  -1057 +/-   9 delay   322 +/-   0

Quad Core 64bit Open Source Hardware Linux computer A64-OLinuXino now have version with external antenna

A64-OLinuXino is Open Source Hardware Quad core 64 bit Linux Computer.

We also offer nice metal box for it named BOX-A64-BLACK:

The only problem was that A64-OLinuXino have option for on board WiFi-BT but it uses PCB antenna and when put in box the communication range was decreasing signiificantly.

New revision of A64-OLinuXino board now supports both internal PCB antenna and U.FL externally attached 2.4Ghz antenna.

So A64-OLinuXino can be put inside the metal box and have the antenna outside:

Open Source Hardware S3-OLinuXino update – The new board targeting industrial vision applications is now with mainline Linux support

S3-OLinuXino is board we create to may add vision to the PTH components Soldering Robot we are working on for some time.

Revision.B now is a bit different than the first prototype we made. It has these features:

  • S3 SOC Cortex-A7 running at 1.2Ghz
  • 1Gb DDR3 RAM inside S3 SOC up to 1333Mhz
  • MIPI Raspberry Pi camera interface up to 8Mpix camera support

Different NAND Flash, SPI Flash, eMMC flash options are possible with addon module

The only thing we still didn’t complete is USB-OTG functionality.

Mass production is planned for March 2021.
