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

  • Layers (openembedded-core, meta-openemedded, meta-riscv, meta-clang) and bitbake were updated to their latest commit.
  • demo-coreip-cli-initramfs was moved to meta-sifive layer from freedom-u-sdk layer. meta-sifive layer contains MACHINE configuration files that directly refer to the initramfs recipe.
  • python3-tensorflow-lite-demo was moved to freedom-u-sdk layer from meta-sifive layer. These only contain demo files.
  • stress-ng was updated to v0.13.08.
  • nbd was updated to 2.23.
  • vmtouch package was added. It allows to load/check/remove files into/from memory cache.
  • All demo-coreip-* disk images were updated to include vmtouch package.

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. If NBD rootfs is used NetworkManager will not handle eth0 interface. This leads to resolv.conf not being generated (DNS resolving doesn't work), and system time is not synchronized via NTP. The Internet connection itself is working.
  7. If NBD rootfs is used NBD client will be terminated too early during systemd shutdown procedure leading to a few IO errors. This happens after the first sync for all filesystems and block devices. Systemd sends SIGSTOP to all processes unconditionally and that's enough for NBD connection to be terminated. To avoid this issue one should need to use --force/-f with poweroff and similar commands. From systemctl man page: If combined with --force, shutdown of all running services is skipped, however all processes are killed and all file systems are unmounted or mounted read-only, immediately followed by the powering off.
