New iMX8QuadPlus System on Module is ready for prototyping

iMX8Quad Max board we developed is still waiting for components to verify the first prototypes, but we decided to develop one more SOC from iMX8 Plus series which we thought is filling niche where we do not have product.

This is how iMX8MPLUS-SOM was designed:

  • MIMX8ML8DVNLZAB – Quad Core Arm Cortex-A53 running at 1.8Ghz with Arm Cortex-M7 co-processor running at 800Mhz and 2.3 TOPS Neural Processing Unit.
  • 6GB LPDDR4 RAM
  • Power management
  • configuration EEPROM
  • status LED
  • LCD LVDS connector compatible with LCD-OLinuXino displays
  • MIPI DSI connector
  • 2x MIPI CSI comera connectors with Raspberry Pi compatible pinout
  • 220 signals on 6 0.05″ step connectors with essential peripherials like:
    • PCIe-3.0
    • 2x CAN FD
    • HDMI 2.0a
    • SPDIF
    • SAI
    • 2x USB 3.0
    • 2x Gigabit Ethernet one of them with TSN
    • eMMC 5.1
    • SDIO 3.0 200Mhz
    • 4 UART
    • 6 I2C
    • 3 SPI
    • JTAG

MIMX8ML8DVNLZAB operating temperature is -40+105C which makes it perfect for both industrial and automotive applications.

Evaluation board iMX8MPlus-SOM-EVB is now designed with Dual Ethernet, Dual USB 3.0, PCIe, HDMI.

NXP is going to provide mainline Linux support for this SOC.

It’s impossible to comment any pricing at the moment, but it will be very competitive compared with similar industrial grade products.

STMP157-SOM-EXT, STMP157-SOM-IND and STMP1(A13)-SOM-EVB are in stock!

Now our first STMP1 boards can be ordered on our web:

STMP1(A13)-SOM-EVB evaluation board (requires separate SOM)

STMP157-SOM-EXT extended temperature range -20+85C running on 800Mhz

STMP157-SOM-IND industrial temperature range -40+85C running on 650Mhz

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!

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

Implementation of OPC UA on ESP32-EVB

OPC Unified Architecture (OPC UA) is an open, implemented under GPL 2.0 license, machine to machine communication protocol for industrial automation developed by the OPC Foundation.

The OPC UA protocol specification consists of 14 documents for a total of 1250 pages. Due to this complexity, existing implementations are usually incomplete.

This is why we were puzzled to see on Twitter post by Selftronics that they made OPC UA server running on ESP32-EVB!

Here are the details of the implementation, the sources are at GitHub.

Fruit selection machine made with T2-OLinuXino-LIME2 and MOD-IO, runs OpenCV

As part of the OSIE project Nexedi SA, France built a small conveyor belt using entirely open-source products and technologies.

Their goal was to build a fruit selection machine, which would use AI (starting with OpenCV) to inspect fruits (and possibly many other small particles) and to do a physical separation (selection) of them.

Olimex have been chosen as a partner in the project because of the many of OSHW solutions which the company offers.

T2-OLinuXino-LIME2 and MOD-IO were used in the implementation.

Details for the project is available here.

New OSHW board with STM32F303 now can have CAN and USB working at same time, operates from -40+85C and with power supply from 4.2-40VDC

OLIMEXINO-STM32F3 is re-design of our popular OLIMEXINO-STM32 board.

What is new?

  • STM32F303RCT6TR is used which allow CAN and USB to work at the same time. The F1 Series of STM32 shared same buffer for both USB and CAN which leads to not be able to work with both CAN and USB at the same time. This is solved in F3 series
  • Increased amount of memory: 256KB Flash, 40KB RAM
  • Power supply is now from 4.2VDC up to 40VDC which allow OLIMEXINO-STM32F3 to work in Automotive applications without special power converters
  • Industrial temperature grade -40+85C
  • Real Time Clock backup battery holder for CR2032 Li battery
  • Lower cost

The price of OLIMEXINO-STM32F3 is EUR 14.95 for single unit and drops to EUR 11.96 for 50+ pcs order.
