网络部分，两路 RGMII 千兆以太网使用 YT8531SH-CA PHY（TSN 交换），两路 MII 10/100Mbps 以太网使用 RTL8201FI PHY（EtherCAT 或通过跳线改为 TSN）。USB 包含一路 i.MX RT1186 USB 2.0 Type-C OTG 与一路 MCU-Link USB Type-C，任一 Type-C 口均可为板卡 5V 供电。工业 I/O 采用 NXP TJA1057BT 高速 CAN 收发器。
扩展接口包括 Arduino UNO R3 + FRDM 排针（UART、SPI、I2C、ADC、PWM、GPIO）、兼容 FRDM-MC-LVPMSM 等子板的的双路电机控制排针、50 引脚 SRAMC 排针（异步 SRAM / FPGA）。其他还有电源滑动开关、5 颗按键、RGB LED 与拨码开关选择启动模式。
软件方面，FRDM-IMXRT1186 由 MCUXpresso SDK 支持，提供 FreeRTOS、lwIP、EtherCAT、多核、USB、安全与外设驱动等示例；开发工具涵盖 MCUXpresso for VS Code、MCUXpresso IDE、IAR Embedded Workbench、Keil MDK 与带 CMake 的 Arm GCC。该板同时支持 Zephyr RTOS，有独立的 CM33 与 CM7 目标及以太网、FlexCAN-FD、LPSPI、LPUART、ADC、PWM、GPIO 驱动。工业网络支持 EtherCAT、PROFINET、EtherNet/IP、Modbus TCP、TSN 与 OPC UA，另涵盖 TrustZone-M、EdgeLock Enclave、MCUBoot、OTA 升级、eIQ、FreeMASTER 与安全配置。
笔者早在 2022 年 NXP 将千兆 TSN 与 EtherCAT 引入其跨界 MCU 产品线时就报道过 i.MX RT1180。此前也已报道过多款 FRDM 板卡，包括基于 Cortex-M33 的 FRDM-MCXA 系列与运行 Linux 的 FRDM-IMX95-PRO，但 FRDM-IMXRT1186 是第一块基于 i.MX RT 系列的 FRDM 开发板。
NXP FRDM-IMXRT1186 目前状态为在售，售价 85.00 美元，设计文件、软件下载与用户手册可在 NXP 产品页面获取。

NXP recently introduced the FRDM-IMXRT1186 development board, based on the i.MX RT1186 crossover MCU, targeting industrial automation, robotics, PLC and edge computing applications. The MCU adopts a heterogeneous architecture: an Arm Cortex-M7 application core running at up to 800MHz handles computation, while an Arm Cortex-M33 core running at up to 300MHz handles real-time control and communications.
The board is equipped with 64Mbit HyperRAM, 512Mbit HyperFlash and 128Mbit QSPI Flash, provides two gigabit Ethernet ports for TSN switching, and two 100Mbps Ethernet ports for EtherCAT or TSN switching. It also has a USB Type-C OTG interface and a CAN transceiver; debugging is supported by an onboard MCU-Link debugger and a JTAG connector. For expansion, it provides Arduino UNO R3 and FRDM pin headers, a FlexSPI follower pin header, an SRAMC pin header and a motor-control pin header.
Key specifications
The SoC is NXP MIMXRT1186CVJ8C (i.MX RT1180 series, LFBGA196 package). The Cortex-M7 application core includes an FPU, 32KB I-cache, 32KB D-cache and up to 512KB of TCM with ECC; the Cortex-M33 security/communication core includes TrustZone-M, 16KB I/D caches and 256KB of TCM with ECC, and is accompanied by a TÜV-certified self-test library. On-chip memory provides up to 1.5MB of ECC-protected SRAM.
For networking, two RGMII gigabit Ethernet channels use the YT8531SH-CA PHY (TSN switching), and two MII 10/100Mbps Ethernet channels use the RTL8201FI PHY (EtherCAT or, via jumpers, TSN). USB includes one i.MX RT1186 USB 2.0 Type-C OTG and one MCU-Link USB Type-C; either Type-C port can supply 5V to power the board. Industrial I/O uses the NXP TJA1057BT high-speed CAN transceiver.
Expansion interfaces include Arduino UNO R3 + FRDM pin headers (UART, SPI, I2C, ADC, PWM, GPIO), a dual-channel motor-control pin header compatible with subboards such as FRDM-MC-LVPMSM, and a 50-pin SRAMC pin header (asynchronous SRAM / FPGA). Other features include a power slide switch, five buttons, an RGB LED, and a DIP switch for selecting boot mode.
On the software side, FRDM-IMXRT1186 is supported by the MCUXpresso SDK, providing samples for FreeRTOS, lwIP, EtherCAT, multicore, USB, security and peripheral drivers; development tools include MCUXpresso for VS Code, MCUXpresso IDE, IAR Embedded Workbench, Keil MDK and Arm GCC with CMake. The board also supports Zephyr RTOS, with separate CM33 and CM7 targets and drivers for Ethernet, FlexCAN-FD, LPSPI, LPUART, ADC, PWM and GPIO. Industrial network support includes EtherCAT, PROFINET, EtherNet/IP, Modbus TCP, TSN and OPC UA, while also covering TrustZone-M, EdgeLock Enclave, MCUBoot, OTA upgrades, eIQ, FreeMASTER and security configuration.
The author reported on i.MX RT1180 back in 2022, when NXP introduced gigabit TSN and EtherCAT to its crossover MCU product line. Several FRDM boards have also been reported previously, including the Cortex-M33-based FRDM-MCXA series and the Linux-running FRDM-IMX95-PRO, but FRDM-IMXRT1186 is the first FRDM development board based on the i.MX RT series.
NXP FRDM-IMXRT1186 is currently available for sale at a price of USD 85.00; design files, software downloads and the user manual can be obtained from the NXP product page.
