Running Linux on the application cores while FreeRTOS handles hard real-time work on a separate pair of processors is exactly the kind of split embedded developers want, and the new DEBIX T62P-01 from Polyhex Technology delivers it on a single 88 x 59 mm board. The heterogeneous layout comes from the Texas Instruments Sitara AM62P, which combines a quad-core Arm Cortex-A53 clocked up to 1.4 GHz with two Cortex-R5F real-time cores running at up to 800 MHz. One R5F core is meant for MCU-class control tasks and the other for device management, so time-critical loops stay off the Linux scheduler entirely.
Polyhex lists Linux 6.12.y, Android 16, and FreeRTOS for the R5F cores, and the AM62P is in good shape upstream: the SoC family already has device tree support in the mainline kernel, with recent patches landing for other AM62P boards. Graphics run on an Imagination IMG BXS-4-64 GPU rated at 50 GFLOPS with support for OpenGL ES 3.2, Vulkan 1.2, and OpenCL 1.2 EP, which makes the board viable for Wayland compositors, GPU-accelerated HMI stacks, and lightweight compute. There is no dedicated NPU, so any AI inference falls back to the A53 cores or the GPU.
The board ships with 2GB of LPDDR4 as standard and options for 4GB or 8GB, alongside optional eMMC in sizes from 8GB up to 256GB, QSPI NOR flash up to 4GB, and a MicroSD slot. Display output covers dual-channel LVDS and 4-lane MIPI DSI, both up to 3840 x 1080, plus a 4-lane MIPI CSI camera input handling 5MP, 8MP, and 13MP sensors. Networking is the standout for anyone building deterministic Ethernet setups: two Gigabit RJ45 ports with TSN support, one of which can take Power over Ethernet through an optional external PD module, backed by Wi-Fi 6 and Bluetooth 5.4. A 40-pin header exposes up to 4x UART, 2x SPI, 2x I2C, a CAN bus, 2x PWM, and 4x GPIO.
One detail aimed squarely at people who actually debug multicore silicon: a dedicated USB Type-C port breaks out three separate UART domains for the A53, R5F-MCU, and R5F-Wake channels, so monitoring the whole asymmetric system no longer means juggling three serial adapters. Security is handled in hardware with secure boot anchored to a Root-of-Trust, an Arm TrustZone-based Trusted Execution Environment, and an HSM covering AES, SHA, PKA, and a true random number generator. The board draws 5V/3A over a separate USB-C power input, weighs 50 grams, and is rated for -20°C to 70°C (-4°F to 158°F), with an optional wide-temperature variant spanning -40°C to 85°C (-40°F to 185°F).
As is typical for industrial hardware, Polyhex has not published pricing. Configurations vary by RAM (2GB, 4GB, or 8GB), optional 64GB eMMC in the standard SKUs, and the choice of standard or wide-temperature grade, with full specifications on the DEBIX product page.
