miriac MPX-LS1028A NXP QorIQ LS1028A SoM Targets TSN Applications with HMI Display

NXP QorIQ LayerScape LS1028A communication SoC was first unveiled in March 2017 with two Armv8 cores, GPU and LCD controller for HMI systems, as well as Time-Sensitive Networking (TSN) capabilities useful in industrial settings.

As usual it takes a while before the company finalize their design and software support, but LS1028A has started to appear at least in one hardware platform that’s supposed to launch this quarter (Q2 2019): MicroSys miriac MPX-LS1028A system-on-module.

The board supports Linux, and MicroSys Microware OS-9 real-time OS is planned for Q3 2019 with support for the open source OPC UA-TSN project aiming to provide a unified standard for industrial automation and IIoT connectivity.

I had never heard about Microware OS-9, but it’s not exactly new as according to Wikipedia, the first version of the real-time system “OS-9 Level One” was written back in 1979–80 in assembly language for the Motorola 6809 CPU. However, since February 2013 Microware OS‐9 is owned by a partnership of three companies, MicroSys, Freestation(Japan) and RTSI (USA) who formed Microware LP to actively continue the development on OS‐9, and recent developments provide support for e.g. ARM Cortex A CPU series integrated for example in NXPs Layerscape LS1043A, LS1046A or LS1088A CPU.

There’s no price information for miriac MPX-LS1028A system-on-module, and limit number of samples are available through the company’s early access program. miriac SBC-LS1028A development kit which includes a SoM, carrier board, Linux BSP, and accessories should also become available, but not details are provided about the kit. More information may eventually be added to the product page.
