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

  • Layers (openembedded-core, meta-openemedded, meta-riscv, meta-clang, meta-tensorflow-lite) were updated to their latest revisions.
  • Updated all files to a new override syntax ("_" separator character was replaced by ":"). There is no way to support old and new syntax at the same time.
  • xf86-video-amdgpu was updated to 21.0.0.
  • mesa was updated to 21.1.5.
  • binutils was updated to 2.37.
  • root password in the SiFive disk images is now stored in SHA512 encrypted form (the password itself did not change).
  • demo-coreip-xfce4 disk image gained new packages:
    • xf86-video-modesetting
    • xf86-video-fbdev
    • perf-python
  • demo-coreip-cli disk image gained new packages:
    • perf-python
  • stress-ng was updated to 0.13.0.
  • util-linux sub-package doc gained support for alternatives to fix man page conflicts at install time.
  • libunwind was enabled for riscv64. The recipe is set to non-release git commit 1527061fc5ce7cfd3911ac7ee8af04fdd4393477. The official support will land in v1.6.0 release (v1.6.0-rc1 is already available on their GitHub repository).
  • perf PACKAGECONFIG was chaged to add dwarf, libunwind, manpages, jvmti, and cap options.
  • linux-mainline_5.13 was rebased on top of v5.13.9 kernel and gained compatibility with qemuriscv64, qemuriscv64_b, qemuriscv64_b_zfh, and qemuriscv64_v machines.
  • Kernel defconfig was modified to include VirtIO options required for QEMU machines:
CONFIG_VIRTIO_BLK=y
CONFIG_SCSI_VIRTIO=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_CONSOLE=y
CONFIG_VIRTIO=y
CONFIG_VIRTIO_MENU=y
CONFIG_VIRTIO_PCI=y
CONFIG_VIRTIO_PCI_LEGACY=y
CONFIG_VIRTIO_BALLOON=y
CONFIG_VIRTIO_MEM=y
CONFIG_VIRTIO_INPUT=y
CONFIG_VIRTIO_MMIO=y
# CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES is not set
CONFIG_VIRTIO_FS=y
CONFIG_CRYPTO_DEV_VIRTIO=y
CONFIG_NET_9P_VIRTIO=y
CONFIG_HW_RANDOM_VIRTIO=y
CONFIG_DRM_VIRTIO_GPU=y
CONFIG_RPMSG=y
# CONFIG_RPMSG_CHAR is not set
CONFIG_RPMSG_VIRTIO=y
  • All QEMU machines (qemuriscv64, qemuriscv64_b, qemuriscv64_b_zfh, and qemuriscv64_v) now have PREFERRED_PROVIDER_virtual/kernel set to linux-mainline.

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 the command from #6 above 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.
