Safety, Compliance, and Legal

License

The NexatomTT SDK is licensed for applications operating Nexatom hardware. The package’s terms define permitted use/redistribution, restrictions and applicable exceptions; this summary does not replace them.

For the complete and legally binding terms of use, refer to the LICENSE.txt file included in the root directory of the SDK distribution.

Third-Party Notices

To provide high-performance hardware interfacing and data processing capabilities, the NexatomTT SDK distributes and links against several third-party libraries:

• FTDI D3XX Runtime: Distributed under the proprietary FTDI Chip software license.
• GCC Runtime Libraries: (libgcc, libstdc++) Supplied under their applicable GNU GPL terms with the GCC Runtime Library Exception; retain the full notices and exception text.
• MinGW-w64 winpthreads: Distributed under permissive open-source licenses.
• HDF5 (1.14.6): Utilized for processed data exports, distributed under the HDF Group / NCSA BSD-style license.

For exact copyright attribution, maintainer lists, and the full text of these licenses, refer to the THIRD_PARTY_NOTICES.md file included in the SDK root.

Firmware Safety Notice

[!CAUTION] Field Update Interruption Risk When executing a firmware field update via the SDK (or field_update_e2e.py), do not disconnect USB or interrupt power while writing. Check the final successful load/verification result; the progress API uses its documented COMPLETED/FAILED phases, not a FINALIZE phase.

• Image Validation: Only flash firmware images that adhere to the <NAME>_<VERSION>.bin convention and have been explicitly provided by Nexatom for your exact hardware model (e.g., UTT810).
• Boot Failures: A corrupt or incompatible default image can prevent runtime boot. Recovery depends on the service firmware and remaining valid slots; do not assume recovery is guaranteed. Preserve a known-good image where possible.

The SDK bundles the current firmware catalogue in its firmware/ folder (manifest plus images); later catalogues are published as firmware-catalog-N releases, which the Nexatom app finds through https://downloads.nexatom.in/firmware/latest.json. Load only an image whose manifest entry names your model, and check its size and SHA-256 against that manifest. Keep the complete platform package, FTDI/vendor licenses and notices. Linux includes the bundled FTDI D3XX userspace library and optional USB permission rule; Windows includes FTD3XXWU.dll and uses its matching FTDI driver. The compiler runtime is linked into the native library, so no separate runtime DLLs are needed.
