NXP i.MX RT series crossover processors were first announced last year as processors providing the same real-time capability as found in microcontrollers while providing performance similar to entry-level application processors thanks to an Arm Cortex-M7 core clocked at up to 600 MHz. i.MX RT series also lower BoM thanks to integrated PMIC and up to 512KB SRAM/TCM.
Later on uCLinux for NXP i.MX RT1050 evaluation board was released, and a few months ago, we covered the upcoming VisionSOM-RT industrial system-on-module powered by the crossover processor. That means we did not have production-ready commercial solutions so far, but this has changed recently, with for example Forlinx Embedded OK1052-C board.
The solution is comprised of a baseboard and a system-on-module with the following specifications:
- FET1052-C SoM
- SoC – NXP i.MX RT1052 single core Arm Cortex-M7 crossover processor @ up to 528 MHz with 512KB SRAM/TCM
- System Memory – 16MB or 32MB SDRAM
- Storage – 4MB to 16MB QSPI Nor Flash
- Board to board connectors – 2x 80-pin connectors with 0.8mm pitch:
- Display – 1x RGB888 LCD interface up to 1366×768 resolution
- Camera – 8-bit DVB interface for 5MP camera
- Storage – Up to 2x SD or SDIO card with 1-bit or 4-bit mode
- Audio – Up to 3x I2C, 1x S/PDIF
- Networking – 1x 10/100Mbps Ethernet
- Up to 8x UART, up to 4x host/device SPI interfaces, up to 4x I2C
- Up to 32x PWM, up to 2x CAN 2.0B buses
- 2x 12-bit ADC up to 20 channels
- 8×8 keypad
- Up to 2x ISO7816-3 interfaces for smart cards
- 1x 16-bit parallel SEMC (Smart External Memory Controller) bus
- Supply Voltage – 5V
- Dimensions – 43 x 31 x 1.6 mm (4-layer PCB)
- Temperature Range – -40 to +85°C
- OK1052-C Carrier Board
- Storage – Micro SD card slot, 256 bytes EEPROM
- Display
- LCD RGB565 I/F up to 1366×768 resolution
- Resistive touch via TSC2007 chip, 4x ADC
- PWM for LCD backlight
- Camera – 8-bit DVP connector for 5MP camera
- Audio – 3.5mm microphone and earphone jacks
- Networking – 100Mbps Ethernet (RJ45)
- USB – 1x USB host port, 1x micro USB OTG port
- Expansion
- 10-pin UART2 header, 10-pin SPI header, 8-pin keypad header; all 2.54mm pitch
- CAN bus screw terminal
- Resistor adjustable ADC
- Debugging – RS232 DB9 connector for serial debugging, 8-pin SWD debug port
- Misc – RTC + battery slot; 1x user LED; reset, wake-up and power buttons, power switch, BOOT DIP switch for booting mode selection
- Power Supply – TBD via power barrel jack
- Dimensions – N/A
The company provides both MCU code samples, and uClinux BSP with demos for all main functions of the board to their customers. Not of the code is provided publicly, so it looks like you’d have to purchase the board before having a look at the code.
Both the module and carrier board appears to be available now, but the price has not been disclosed either. You’d have to contact the company for more details about software support and pricing via their product page.

I’ve been told the board should also run Zephyr OS after a few changes: https://github.com/zephyrproject-rtos/zephyr/tree/master/soc/arm/nxp_imx/rt
It reminds me of the erly 2000s when bsps of overpriced dev boards were treated as trade secrets…
I thought this mentality was a thing of the past. Seems i was wrong.
I Have This Board, The FOrlinx RT1052 Linux Code are bought from emcraft.
I think once you’re using something over a few hundred megahertz you really should have a cortex A core with a proper MMU.
With so many peripherals writing data all over the place at a decent pace it won’t be long before something has crapped over something else and it’s just a matter of time before it crashes or worse goes out of control.
NXP should really offer something like the imx6ull with integrated DDR and a cortex M? co-processor.
why power not usb c ?
for laptop working why not for this dev
