FAQs on Software Development
Does TQ only develop software for its own hardware platforms, or also for third-party hardware?
TQ develops software both for its own TQ modules and baseboards and for customer-specific hardware platforms. Early coordination between hardware and software development is important – something that is naturally shortest in internal TQ projects, but is also ensured for customer hardware through structured interface definition.
Which embedded operating systems and build systems does TQ use in software development?
TQ develops embedded Linux board support packages for QorIQ®, Arm®, and x86 architectures using modern build systems such as Yocto, PTXdist, Buildroot, and OpenWRT. For real-time requirements, Preempt-RT Linux and Xenomai are used. Debian and Ubuntu are used as standard distributions. In addition, TQ also develops RTOS-based firmware for microcontrollers, such as FreeRTOS, ThreadX, and Zephyr, as well as UEFI/BIOS and bootloaders such as U-Boot and GRUB.
Can TQ also develop software for regulated industries such as medical technology or aviation?
Yes. TQ develops software in accordance with relevant standards – DO-178B/C (DAL C–E) for aviation, IEC 62304 for medical devices, and IEC 61508 for functionally safe systems. The development processes are set up and documented accordingly, including requirements engineering, threat analyses, and comprehensive testing.
How does TQ integrate IoT functions into existing products?
TQ offers retrofit integration for existing devices – using IoT gateways, cloud interfaces, and customer-specific IoT interfaces. Supported communication protocols include MQTT, OPC UA, Wi-Fi, LTE/LTE-M, ZigBee, and Z-Wave. This allows existing products to be retrofitted with cloud services and monitoring functions.
Does TQ also develop mobile apps to complement embedded systems?
Yes. TQ develops native and cross-platform apps for iOS and Android as customer-specific applications, service apps for status display and control, or desktop applications for communication with embedded devices. Both platform-specific and cross-platform code bases are possible.
How does TQ ensure the quality and security of the developed software?
TQ relies on a structured development process with code reviews, white-box and black-box testing, and defined approval points. In the area of cybersecurity, TQ conducts threat analyses and develops appropriate countermeasures. License conformity clearing ensures that open-source components are used in a legally compliant manner.
