Hardware Requirements

Where possible, WITTENSTEIN high integrity systems (WHIS) will procure the processor specified by the customer on a commercially available evaluation board. If this is not feasible (for example, where no suitable evaluation board exists), the customer must provide their own hardware platform and board support package.

The customer bears full responsibility for supplying a fully functional and production-ready hardware platform suitable for SAFERTOS integration. WHIS does not provide hardware debugging, fault diagnosis, or hardware bring-up services.

Customer-supplied hardware requirements

To be accepted for use, the customer-supplied hardware must meet the following mandatory requirements:

1. The hardware must be complete, and fully functional, operating correctly “out of the box” without any additional effort required by WHIS.
2. A fully operational and validated debug interface must be present.
3. Any special cables, connectors, or adapters required to connect the selected JTAG emulator must be supplied by the customer.
4. If the hardware is delivered in a disassembled state, the customer must provide clear, comprehensive assembly instructions, including annotated photographs where necessary.
5. The customer must provide all required technical documentation, including schematics, datasheets, and any additional design information necessary for software integration.
6. For SafeRTOS packages requiring DAP or DHF documentation, the hardware must provide:
   • At least 1 accessible LED (or GPIO).
   • Ideally 2 UART interfaces.
7. The hardware, particularly the debug interface, must have been fully validated by the customer prior to delivery. This includes successfully programming and running a basic application using the intended toolchain and JTAG emulator.
8. The hardware, especially the debug interface, should have already been tested by the customer, using their selected JTAG emulator (e.g. downloading a “Hello World” program).
9. The customer must supply a working “Hello World” (or equivalent) application, along with all necessary build instructions, configuration settings, and tooling required to demonstrate correct hardware operation.

Important considerations

A) WHIS may, at its discretion, perform a basic verification test of the supplied hardware; however, this activity does not constitute project commencement and is solely intended to confirm that the platform meets the stated requirements.

B) If, at any stage, the hardware is found to be non-functional, incomplete, unstable, or otherwise unsuitable for SAFERTOS integration, WHIS will not undertake hardware investigation or remediation. Any resulting delays may require project rescheduling, and WHIS reserves the right to defer or cancel the allocated development slot.

Responsibility and Limitations

WHIS specialises exclusively in high-quality software development. Responsibility for ensuring the hardware platform (including the debug interface) is fully operational rests entirely with the customer.

If the provided hardware is found to require modification, repair, or additional development effort in order to support SAFERTOS integration:

• WHIS will not perform such work.
• The customer will be required to resolve all hardware issues independently or supply an alternative, fully functional platform.
• Any delays caused by unsuitable hardware will impact delivery timelines.
• If additional unforeseen effort is required due to hardware-related constraints, WHIS reserves the right to revise project scope, schedule, and commercial terms accordingly.
