Webinars explore RTOS-to-Linux driver migration

Nov 20, 2008 — by Eric Brown — from the LinuxDevices Archive — 5 views

MontaVista Software announced two educational webinars on porting real-time operating system (RTOS) drivers to embedded Linux. Presented by's Bill Weinberg (pictured) on Dec. 9, the webinars will show developers how to migrate their device interfaces from VxWorks to Linux, says MontaVista.

Weinberg was a founding MontaVista employee who went on to contribute significantly to Carrier Grade Linux and other OSDL specs, working for several years as a Senior Technology Analyst for the group before it became the Linux Foundation. Ever erudite and always well-spoken, Weinberg is an intellectual omni-competent who regularly leads Linux events and, we suspect, regularly ghost-writes entries for widely read embedded and mobile industry blogs. He's shared quite a few papers and much candid industry insight with LinuxDevices through the years, and currently keeps his home-on-the-Web at

The webinars follow up on a somewhat similar webinar held on Oct. 23, in which MontaVista founder and CTO Jim Ready described how to port VxWorks applications to embedded Linux. Moderated as before by Don Dingee, the new webinars will take a deeper dive into driver migration, says the company.

Weinberg will offer background on the architecture and conventions of drivers built for VxWorks, says MontaVista. He will also offer guidelines for mapping code and constructs onto Linux, as well as tips for migration and debugging. Weinberg will also reveal how moving to Linux can provide RTOS developers with new opportunities for refining I/O architecture and formalizing system interfaces.

Specific topics covered during the webinars include:

  • Particulars of legacy VxWorks device interfaces
  • Heuristics, community and MontaVista resources, and examples for migrating to embedded Linux
  • Architecture and conventions of drivers built for VxWorks
  • Guidelines for mapping code and constructs onto Linux 2.6
  • Options for kernel and user space implementations and licensing implications
  • Migration and debugging tools and techniques


MontaVista is offering the free, one-hour webcast, “Migrating Legacy RTOS Device Drivers to Embedded Linux,” on Tuesday, Dec. 9. at 7AM and 4PM EST. Attendees will receive a free white paper on VxWorks-to-Linux migrations, says MontaVista. More information may be found here.
