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.
