Linux-Driven SMARC Module Supports Up to Five Time-Sensitive GbE Ports

By Eric Brown

Kontron invented the ULP-COM standard that formed the basis of the SMARC form factor, and it has delivered numerous SMARC modules over the years, including Arm products such as the Nvidia Tegra K1 based SMC-NTKE1. Now it has unveiled the first module we’ve seen in any form factor with NXP’s dual-core, Cortex-A72 powered QorIQ Layerscape LS1028 SoC.

The 82 mm x 50 mm SMARC-sAL28 module runs a Yocto Project based Linux stack (with U-Boot) on the LS1028. The module exploits the SoC’s Time Sensitive Networking (TSN) support with up 2x or 5x TSN-capable Gigabit Ethernet ports.

The SMARC-sAL28 module is compliant with the IEEE 802.1 TSN standard, which offers guaranteed latency and Quality of Service (QoS) with time synchronization to enable “a timely and highly available delivery of data packets,” says Kontron. TSN Ethernet can replace more expensive, proprietary fieldbus technology while also offering the advantage of being able to “simultaneously communicate seamlessly to the IT level.”

No clock rate was listed for the LS1028 SoC, which NXP refers to as the LS1028A. The SoC integrates a four-port TSN switch and two separate TSN Ethernet controllers. Like NXP’s other networking oriented LSx QorIQ Layerscape SoCs, it supports NXP’s EdgeScale suite of secure edge computing device management tools. It’s the only LSx SoC that features a 3D graphics capable GPU.

The SMARC-sAL28 ships with 4GB of soldered DDR3L with optional ECC, as well as 2GB to 64GB eMMC 5.1 storage. The 3V-5.25V module supports -40 to 85°C operation.

Two models are available. One has 2x TSN-capable, switched GbE controllers “that can be directly used by the carrier,” says Kontron. The second version supports 4x switched TSN-capable GbE ports via the QSGMII interface with an additional TSN-capable GbE controller. This second option provides a total of 5x TSN-ready GbE ports ports “using a quad-PHY on the carrier.” This 5x GbE model sacrifices one of the 2x PCIe x1 interfaces, which can also be deployed as a single PCIe x4 connection.

The SMARC-sAL28 provides a dual-channel LVDS interface, one of which can be swapped out for eDP as a BOM option. The second LVDS offers a BOM option swap-out for either an HDMI or DisplayPort.

The module is further equipped with a single USB 3.0, 6x USB 2.0, and 4x RX/TX serial interfaces. Other I/O includes 2x I2C, 2x SPI, 12x GPIO, and single SDIO, CAN, and I2S connections. Options include a Wibu security chip with Kontron Approtect security software, as well as an RTC.

Further information

The SMARC-sAL28 is “coming soon” at an undisclosed price. More information may be found in Kontron’s SMARC-sAL28 announcement and product page.

SMARC SOMs Used for Walmart Robotic Retrieval System

Axiomtek has announced its ongoing collaboration with Alert Innovation. Alert Innovation has been tapped by Walmart to use its robotics technology to automate their grocery operations. The company has developed the Alphabot system, an Automated Storage and Retrieval System (ASRS) that is also an Automated Each-Picking System (AEPS). Axiomtek’s embedded computers and SMARC System on Modules (SOMs) are used in the system.
For a period of almost two years prior to the announcement of the Alphabot pilot test in a Walmart Supercenter, the Axiomtek team worked alongside Alert Innovation’s engineering team, helping to identify and customize products for Alert’s use, participating in schematic reviews and supporting driver development to ensure seamless integration. Since then, Axiomtek has continued to invest in and support the Alert Innovation Alphabot system’s mission.

A number of products have been tailored to balance performance and cost effectiveness, mitigate the challenges associated with refrigerated and frozen environments by adding conformal coatings and integrate application-specific interfaces. According to Alert Innovation, said Matthew Coady, Senior Director of Electrical Engineering and Controls. “We chose them because their products and team consistently met our stringent project requirements, delivering quality, performance, support, and all the features our applications required,” said Matthew Coady, Alert Innovation’s Senior Director of Electrical Engineering and Controls, “The SMARC SOM that we selected fits in our space-constrained application and helped us come to market quickly. If (and when) our application needs more processing power, memory or storage, Axiomtek has a range of products in their portfolio and roadmap that will help keep our hardware platform viable for many years to come. Axiomtek was quick to provide us with a BSP for our QNX operating system, and carrier integration support.”

SMARC Module Features Hexa-Core i.MX8 QuadMax

By Eric Brown

iWave has unveiled a rugged, wireless enabled SMARC module with 4 GB LPDDR4 and dual GbE controllers that runs Linux or Android on NXP’s i.MX8 QuadMax SoC with 2x Cortex-A72, 4x -A53, 2x -M4F and 2x GPU cores.

iWave has posted specs for an 82 mm x 50 mm, industrial temperature “iW-RainboW-G27M” SMARC 2.0 module that builds on NXP’s i.MX8 QuadMax system-on-chip. The i.MX8 QuadMax was announced in Oct. 2016 as the higher end model of an automotive focused i.MX8 Quad family.

Although the lower-end, quad-core, Cortex-A53 i.MX8M SoC was not fully announced until after the hexa-core Quad, we’ve seen far more embedded boards based on the
i.MX8M , including a recent Seco SM-C12

iW-RainboW-G27M (back)

SMARC module. The only other i.MX8 Quad based product we’ve seen is Toradex’s QuadMax driven Apalis iMX8 module. The Apalis iMX8 was announced a year ago, but is still listed as “coming soon.”

Like Rockchip’s RK3399, NXP’s i.MX8 QuadMax features dual high-end Cortex-A72 cores and four Cortex-A53 cores. NXP also offers a similar i.MX8 QuadPlus design with only one Cortex-A72 core.

The QuadMax clock rates are lower than on the RK3399, which clocks to 1.8 GHz (A72) and 1.2 GHz (A53). Toradex says the Apalis iMX8’s -A72 and -A53 cores will clock to 1.6 GHz and 1.2 GHz, respectively.

Whereas the i.MX8M has one 266 MHz Cortex-M4F microcontroller, the Quad SoCs have two. A HIFI4 DSP is also onboard, along with a dual-core Vivante GC7000LiteXS/VX GPU, which is alternately referred to as being two GPUs in one or having a split GPU design.

iWave doesn’t specifically name these coprocessors except to list features including a “4K H.265 decode and 1080p H.264 enc/dec capable VPU, 16-Shader 3D (Vec4), and Enhanced Vision Capabilities (via GPU).” The SoC is also said to offer a “dual failover-ready display controller.” The CPUs, meanwhile, are touted for their “full chip hardware virtualization capabilities.”

Inside the iW-RainboW-G27M

Like iWave’s SMARC 2.0 form factor Snapdragon 820 SOM, the iW-RainboW-G27M supports Linux and Android, in this case running Android Nougat (7.0) or higher. (Toradex’s Apalis iMX8 supports Linux, and also supports FreeRTOS running on the Cortex-M4F MCUs.)

Like Toradex, iWave is not promoting the automotive angle that was originally pushed by NXP. iWave’s module is designed to “offer maximum performance with higher efficiency for complex embedded application of consumer, medical and industrial embedded computing applications,” says iWave.

Like the QuadMax based Apalis iMX8, as well as most of the i.MX8M products we’ve seen, the iW-RainboW-G27M supports up to 4 GB LPDDR4 RAM and up to 16 GB eMMC. iWave notes that the RAM and eMMC are “expandable,” but does not say to what capacities. There’s also a microSD slot and 256 MB of optional QSPI flash.

Whereas Apalis iMX8 has a single GbE controller, iWave’s COM has two. It similarly offers onboard 802.11ac Wi-Fi and Bluetooth (4.1). The Microchip ATWILC3000-MR110CA module, which juts out a bit on one side, is listed by Digi-Key as 802.11b/g/n, but iWave has it as 802.11ac.

Interfaces expressed via the SMARC edge connector include 2x GbE, 2x USB 3.0 host (4-port hub), 4x USB 2.0 host, and USB 2.0 OTG. Additional SMARC I/O includes 3x UART (2x with CTS & RTS), 2x CAN, 2x I2C, 12x GPIO, and single PCIe, SATA, debug UART, SD, SPI and QSPI

Media features include an HDMI/DP transmitter, dual-channel LVDS or MIPI-DSI, and an SSI/I2S audio interface. iWave also lists HDMI, 2x LVDS, SPDIF, and ESAI separately under “expansion connector interfaces.” Other expansion I/O is said to include MLB, CAN and GPIO.

The 5 V module supports -40 to 80°C temperatures. There is no mention of a carrier board.

Further information

No pricing or availability was listed for the iW-RainboW-G27M, but a form is available for requesting a quote. More information may be found on iWave’s iW-RainboW-G27M product page.
