This release includes major changes compared previous Freedom U SDK (FUSDK) release. The notable changes include:

  • meta-sifive was converted to a smaller layer containing the most important packages (e.g. OpenSBI, Linux kernel, U-Boot, etc). All other packages related to building a demo distribution are now in freedom-u-sdk repository (i.e. layer).
  • Layers (openembedded-core, meta-openemedded, meta-riscv, meta-clang) were updated to their latest revisions.
  • stress-ng was updated to 0.13.51.
  • linux-mainline_5.13 (Linux kernel) was updated to v5.13.19.
  • libunwind_git was updated to 97d74d396264720e86d4b8455216f4a7b06a54af commit.
  • qemu RVV, RVB and Zfh patches were removed for now. These extensions are being finalized (currently in a public review stage). The patches as-is do not apply to the latest stable QEMU version available in openembedded-core layer. The next stable QEMU version should have some of these available out-of-the-box.
  • qemuriscv64_b, qemuriscv64_b_zfh and qemuriscv64_v machines are not available (see above).
  • demo-coreip-xfce4 has VAAPI disabled for now as OE attempts to install packages with *initial* in their name, which should be excluded from the dependency list, but are not.
  • nghttp2 sub-packages client and server were removed from the main recipe as the content of them is empty.

Known Issues

  1. Newer OE/Yocto buildtools could cause build issues for nspr-native package. Use -r yocto-3.2_M2 -t 20200729 as described in README file if you are using OE/Yocto buildtools. See Yocto bug #14112
  2. We have found an issue with SanDisk "A2" microSD cards and thus do not recommend them.
  3. If the desktop is unresponsive/frozen (i.e. the keyboard doesn't work or/and the mouse doesn't work, the clock is not updating, etc.) try systemctl restart display-manager from the serial console.
  4. If the keyboard or/and mouse is not responsive/frozen check if the input device is available under libinput list-devices and if events are registered by libinput debug-events in the console. If events are registered try systemctl restart display-manager from the serial console. Otherwise manually unplug and plug the keyboard or/and mouse.
  5. If your desktop is very slow check Mesa OpenGL rendered (glxinfo | grep OpenGL). If it is OpenGL renderer string: llvmpipe restart the system. In rare cases Mesa might fallback to llvmpipe, but restart usually resolved the issue.
  6. Restart is not implemented in software for HiFive Unmatched.
