Edge Node Firmware & FPGA Bitstream Repository

Secure Over-The-Air (OTA) dual-bank ROM packages, FPGA bitstream overlays, embedded real-time kernels, and neural network inference models for 1314996 edge sensing gateways.

01 // SIL-3 Dual-Bank Redundant Bootloader Architecture

All 1314996 SoC modules implement hardware-enforced A/B Dual-Bank Flash Partitioning compliant with ISO/IEC 61508 SIL-3 safety standards. During an active Over-The-Air firmware update, the target gateway downloads encrypted payload binaries into the passive bank while executing continuously from the active bank. Upon signature verification via embedded ECC-256 hardware root-of-trust, the watchdog timer triggers a seamless 12-millisecond atomic switch.

Cryptographic Verification Layer

SHA-256 digest validation coupled with ECDSA-P256 hardware signing. Corrupted payloads or unauthorized third-party bitstreams are discarded automatically without disrupting live sensing tasks.

Automatic Rollback & Watchdog

If a newly booted firmware fails to assert the hardware watchdog heartbeat within 1,000 ms of initialization, the system hardware controller reverts to the known-good primary bank.

03 // Automated REST / HTTPS OTA Ingestion API Guide

Field devices deployed on isolated industrial Ethernet or 5G private networks can trigger automated OTA checks using the standard 1314996-OTA-Agent daemon. Below is the standard HTTPS GET request format for querying the latest signed manifest:

# Querying firmware manifest via device HTTPS client
curl -X GET "https://ota.1314996.local/api/v4/manifest?device_id=EX4-00912¤t_fw=v4.8.0" \
    -H "X-Device-Cert: MIIDDTCCAfWgAwIBAgIU..." \
    --tls-max 1.3

The server responds with an encrypted JSON envelope detailing package size, SHA-256 checksum, and differential delta chunks to minimize cellular network bandwidth.
