Case Study: a European supplier of passenger information systems achieves faster builds and reliable OTA updates with Promwad's unified Yocto Linux platform

a European supplier of passenger information systems cuts TFT image build time from 1 day to 2 hours with Promwad

The client, a European supplier of passenger information systems, faced performance and scalability limits with their existing architecture, which risked slowing deployments and hindering competitiveness. They partnered with Promwad to develop a compact, energy-efficient, and highly productive onboard platform for their railway safety solutions.

Promwad built a unified Yocto-based Linux platform, splitting the legacy codebase into compact OS images for each device type, including TFT displays and telephony servers. This solution provided unified configuration, safe over-the-air updates, and automated builds. As a result, Promwad helped the client restore serial production and drastically reduced image build time from a full day to roughly two hours.
