MontaVista Launches Carrier Grade eXpress (CGX) 3.1 and Steps Up Yocto  Alignment 

MontaVista Software, LLC, announces CGX 3.1, the latest edition of CGX distribution, basedon the Yocto project 3.1 LTS version. The new product is targeting kernel support for Linux 5.4 LTS and has 10 years of standard lifecycle support with extended support options available. MontaVista is focusing efforts to work through the community OpenCGX project and align with the Yocto Project development model.

Santa Clara, CA, June 25, 2020 –– MontaVista® Software, LLC, a leader in commercial Embedded Linux® products and services, today announced the availability of MontaVista’s Carrier Grade eXpress (CGX) 3.1 in Q3 of 2020. The CGX 3.1 release will include the baseline of components from Yocto 3.1, commercialized by MontaVista’s Carrier-Grade build and test infrastructure.

The CGX 3.1 release is planned to contain the Linux 5.4 LTS kernel, with the Yocto 3.1 LTS build system and user-space applications, including features such as:

  • Advanced security: Trusted Boot and Integrity Management solutions to mitigate the exposure of customer’s products on the field
  • Carrier-Grade Maintainability: Field-debugging, logging and tracing solutions to allow lower return rates and improved SW quality
  • Linux Hard Real-time support: Very low-latency processing for latency intensive applications such as industrial control and advanced data processing

CGX 3.1 will also contain improvements supporting the Continuous Integration and Continuous Deployment (CI/CD) facilities. The distribution will be structured to support the customer CI/CD systems by allowing multi-tiered access to software artifacts at different stages of development. This allow customers significant improvements in achieved high-quality and time-to-market, since testing can be conducted at a much earlier stage in development cycle, and defects can be found and corrected at an earlier stage as well. MontaVista is also offering collaborative development services for customer-specific BSP development allowing customers to use MontaVista test harnesses and expertise to produce high-quality products based on the CGX distribution.

The MontaVista CGX 3.1 platform is targeted to be available in Q3 of 2020. The targeted initial set of platforms include x86 and ARM-based architectures with modern SoCsupport, as well as QEMU virtual models for application development and early prototyping.
