Pinnacle

A custom Yocto-based platform for NXP i.MX 8M (Mini / Nano / Plus), i.MX 93, and i.MX 95 — secure, power-efficient, industrial-grade.

• Validated on i.MX 8M family, i.MX 93 (FRDM), scalable to i.MX 95.
• Multi-stage boot: BootROM → SPL → U-Boot → ATF → OP-TEE → Linux.
• Secure boot (HAB / AHAB), EdgeLock security integration.
• RTOS on Cortex-M core (FreeRTOS / Zephyr) with RPMsg.

DDR, power, straps

• Schematic review: DDR configuration and calibration (critical on i.MX), power tree, boot-mode straps.
• Custom BSP: device tree for your board, pinmux via config tools, peripheral integration.
• Board bring-up and smoke test with a structured checklist.
• Custom bootloader: U-Boot SPL port, DDR init, boot-media strategy (eMMC / SD / QSPI).

HAB / AHAB secure boot

• Golden boot development and redundant boot via bootloader fallback logic.
• Memory partitioning, failsafe and rollback boot.
• HAB / AHAB secure boot provisioning and key-management support.
• Factory provisioning designed for regulated manufacturing.

Industrial kernel

• Kernel customization on NXP downstream trees, mainline migration paths.
• PREEMPT_RT porting and validation.
• Boot streamlining: SPL-to-app optimization, sub-2-second HMI boot targets.
• Driver work: V4L2 (MIPI CSI, ISP on 8M Plus), audio (SAI / codecs), display, CAN-FD, TSN.

Industry-specific images

• pinnacle-iot — MQTT, cloud agents, EdgeLock-backed device identity.
• pinnacle-industrial — Modbus, OPC UA, TSN networking, real-time I/O.
• pinnacle-automotive — CAN-FD stacks, RT patch, instrument-cluster fast-boot profile.
• pinnacle-medical — IEC 62304-aligned traceable builds, SBOM.
• HMI stack options: Qt, LVGL, Flutter embedded, Wayland / Weston tuning.

A/B, signed, audited

• A/B OTA (Mender / RAUC / SWUpdate) with golden recovery image.
• Automatic rollback on failed boot or health check.
• Cloud connectivity, staged fleet rollouts, delta updates.
• Updates signed and chained to HAB / AHAB root of trust.

Traceable tooling

• Evaluation images for NXP EVKs (including FRDM i.MX 93) and your custom hardware.
• Application SDK and Yocto eSDK for your application teams.
• Debugging: JTAG (Lauterbach / Segger), kgdb, gdbserver, core-dump pipelines.
• Profiling: perf, LTTng, boot profiling, power profiling.

M7 / M33 cores

• FreeRTOS / Zephyr on the Cortex-M core (M7 on 8M Plus, M33 on i.MX 93).
• RPMsg / Messaging Unit communication with Linux.
• Real-time control, sensor acquisition, low-power supervision on the M-core.
• Heterogeneous architecture design: which workload runs where, and why.

Audit-ready builds

• NPU integration: eIQ runtime on 8M Plus / i.MX 93 Ethos-U65.
• Power management: low-power modes, suspend / resume tuning for battery devices.
• Factory provisioning with per-device keys and identity.
• A platform your product can stand on for a decade.
