Forlinx NXP LS1043A & LS1046A Networking SBC’s Support 10Gbps Ethernet

NXP LS1043A quad-core Cortex-A53 communication processor was introduced in 2014, while NXP LS1046A quad-core Cortex-A72 SoC was launched about 18 months later. Both are designed for networking equipment such as CPE (Customer Premise Equipment), routers, NAS, gateways, as well as single board computers and include one or two 10 GbE interfaces.

Forlinx Embedded has decided to leverage those two processors in their OK1043A-C and OK1046A industrial-grade single board computers designed for networking applications.

So the main difference is that LS1043A can support up to 7 Ethernet ports (1x XFI 10Gbps Ethernet + 6x Gigabit Ethernet), while LS1046A can handle up to 8 Ethernet ports (2x XFI 10Gbps Ethernet + 6x Gigabit Ethernet).

Both boards run Ubuntu 18.04 with Linux 4.14.4 or OpenWrt 17.01 with Linux 4.14.69 , and the company provides complete BSP with source code to their customers (no public download).

Target applications include industrial routers, edge computing gateways, IP-PBX, energy management, automation, and more. Both boards and corresponding modules appear to be available now at an undisclosed price.
