Yocto support for embedded ARM modules

31 January 2018 Computer/Embedded Technology

In parallel with the PTXdist-based board support packages (BSP) for ARM modules, the embedded specialist, TQ, is now also making available a corresponding Yocto Metalayer. Support will initially be provided for the current products, TQMa6x, TQMa6ULx, TQMa7x and TQMLS102xA.

In the last two years, TQ says it has encountered increasing demand for Yocto. Because of the growing number of projects, the company is offering a Yocto Metalayer based on Yocto 2.1 (Krogoth) for the ARM modules. Yocto Project users can include the Metalayer to make it very easy to create boot loader and kernel binaries tailored to the corresponding TQ module. The TQ BSP layer thus provides a solid basis for the production of customer-specific BSPs for the use of TQ modules in the widest variety of customer applications.

Chip manufacturers such as Texas Instruments and NXP support the Yocto Project and offer corresponding BSP layers for their respective evaluation boards. These BSP layers make the support available for the CPUs concerned and are thus the foundation for module-specific BSP layers. These in turn form the starting point for customer-specific BSPs for embedded systems using a TQ embedded module.

When using embedded systems, Yocto provides the advantage that porting of the operating system to customer-specific hardware is simplified. Meanwhile, Yocto has a good infrastructure that also permits the management and creation of platform-independent projects. With Yocto, a stable basis was established for build systems in the embedded systems field, which, amongst other things, takes into account aspects such as licensing issues.
