ESP32-POE and ESP32-POE-ISO back in stock

Silicon Labs stopped selling Si3204 POE controllers which were inside our very popular ESP32-POE and ESP32-POE-ISO boards. There is no stock anywhere neither information when they will be back in stock. So back in August we start searching for alternative and we evaluated several other solutions. We liked most Texas Instruments and made some prototypes and verified that they works fine.

Then we run blank PCBs in production but unfortunately we hit two major Chinese Holidays, so instead the blank PCBs to arrive in the normal 2 weeks we had to wait 5 weeks to produce our order then another week to arrive here.

Meantime we sold out all our stock of ESP32-POE and POE-ISO and created solid backlog before we stop the sales on the web.

We are glad that this week we shipped all backlog orders and now the boards are again for sale!

The new revisions of the boards are REV.G and the PCB info will be updated on GitHub tomorrow. From user point of view nothing changes – the new revision operates exactly the same and have same functionality as the previous Silicon Labs based solution.

STMP157-OLinuXino-LIME2 Open Source Hardware Industrial Grade Linux computer is in mass production with 4 variants

STMP157-OLinuXino-LIME2 Open Source Hardware Linux computer running Mainline Linux is in mass production in four variants:

  • Industrial grade -40+85C (STMP157-OLinuXino-LIME2-IND) version running on 650 Mhz
  • Industrial grade -40+85C (STMP157-OLinuXino-LIME2H-IND) version running on 650 Mhz with HDMI output (when HDMI works operating temperature is commercial as HDMI convertor is not industrial grade)
  • Extended temperature -20+85C (STMP157-OLinuXino-LIME2-EXT) version running on 800 Mhz
  • Extended temperature -20+85C (STMP157-OLinuXino-LIME2H-EXT) version running on 800 Mhz with HDMI output (when HDMI works operating temperature is commercial as HDMI convertor is not industrial grade)

User Manual for the boards is available on the product web page.

Debian and Ubuntu Linux images are pre-build and ready to install and run.

The images are build with Olimex script Olimage which is available on GitHub.

Olimage user manual explains what is included in it and how you can modify uboot and kernel to include drivers for devices which are not included in Olimex official images.

Open Fest 2021 is back! Free your agenda for 14 and 15 of August when the biggest open source event in Bulgaria will take place in Sofia.

It’s good to see that slowly things come back to normal!

Open fest 2021 will be provided in normal face to face format in the open space – the King Boris garden – “Maimunarnika” where up to 1200 people can be hosted.

As always the participation is free of charge.

There will be the traditional soldering party with the help of the Open Fest 2021 volunteers from the Technical University club of Robotics.

Olimex is donating 50 pcs of our new Musical badge kits, which contain only PTH components and are very easy to solder even for beginners:

Musical badge is board with two sensor buttons which start and stop music play when touched.

The Open Fest dates are during our Summer Break so we are not be physically present there but will watch online the event.

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!

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-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
