2022.06.00

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.
• git-repo is no longer used to build Freedom-U-SDK, it has been replaced by kas.
• setup.sh has been replaced by a distro configuration, a few bbappends and a local_conf_header in kas yaml.
• Factorize the demo-coreip-* images definition.
• Some recipes from meta-sifive have been here, because there aren't parts of BSP.
• Block map of images are now generated; to speed up SDCard flashing.
• Vulkan samples are no longer available due to a random build issue.
• Tensorflow-lite examples and the SiFive demo are now installed in the demo-coreip-* images.
• Coremark is now installed in the demo-coreip-* images.
• GLMark2 is now installed in the demo-coreip-xfce4 images.

2022.04.00

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) were updated to their latest commit.
• u-boot was updated to 2022.04.
• linux-mainline was updated to 5.17.

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. AMD RX500 series GPUs are facing regression errors.
8. Intel AX200 series are encountering stability issues on wireless connections.

• stress-ng was updated to 0.13.12.
• mesa local copy was removed and replaced with a bbappend file.
• Removed python backports (python3-distutils-extra, python3-ptyprocess, python3-pybind11, xfce4-whiskermenu-plugin) added in 2022.02.00. These are already part of openembedded-core and meta-openembedded layers.
• nbd was updated to 3.24.
• nghttp2 was rebased to 1.47.0.
• openssh was rebased to 8.9.p1.
