Welcome to the portal for Linux on Xtensa

This portal is the primary resource for the community of developers and users of the Linux operating system on Xtensa processors.

The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core. Processor and SOC vendors can select from various processor options and even create customized instructions in addition to a base ISA to tailor the processor for a particular application.

To quickly get started building Linux from sources for Xtensa: the preferred approach is to clone the latest sources via GIT, as described in the Wiki pages and Buildroot Build Instructions. Alternatively, you can download stable snapshots that include the Linux kernel, U-Boot, and Buildroot.

  The Wiki project is a community effort to collect information and documentation about Linux on Xtensa processors. Developers can also find instructions for building the kernel and development tools.
  Download current and stable snapshots of the Linux kernel, U-Boot, and Buildroot source code. Follow Buildroot Build Instructions on setting up your environment.
  This is the web interface for the mailman list server. It handles subscriptions to project mailing lists and also provides an archive of the lists.
  GIT repositories of the Linux kernel, buildroot, U-Boot, and other packages for the Xtensa architecture.

See Buildroot Build Instructions for general directions on using these git repositories. Also consider looking at the SMP HiFi 2 Development Board support page which has implementation details such as an example of setting up U-Boot as well as tips on dealing with cross compiling and buildroot package issues.

  Bug tracking (not yet in active use).
