2026 July Toolchain and rootfs Binaries
Again, we have created new toolchains and rootfs binaries from upstream stable releases.
You can access them via links on our software page. Or easily access them here:
- Toolchain releases - For binaries of newlib, glibc and musl toolchains.
- Linux rootfs releases - For rootfs images of busybox and buildroot
Have a look at the readme documentation in or1k-utils for pointers on how the rootfs images are be used. We are working on some comprehensive tutorials to also help bring this all together.
The current toolchains available are built with:
- GCC 16.1.0
- Binutils 2.46.0
- GDB 17.1
- Linux (headers) : 6.18.22
- Newlib (elf toolchain) : 4.6.0.20260123
- Musl (linux-musl toolchain) : 1.2.6
- Glibc (linux-gnu toolchain) : 2.43
The current rootfs images available are build with:
You can checkout the release pages above for details on the release notes. We have fixed up a fwe significant bugs in the GCC releases so upgrades in highly recommended for any serious work.
Also, we have been hard at work at updating our Tutorials to be more useful. The tutorials leverage the toolchains and rootfs images to bring up QEMU simulators and FPGA boards including multicore SMP systems.
