2020.06.00

• All layers (openembedded-core, meta-openembedded, meta-riscv) updated to their latest revisions.
• Kernel updated to v5.7.2.
• U-Boot updated to v2020.07-rc4.
• GCC update to 10.1.0.

Known Issues

1. Avoid overclocking SoC using CPUFreq if you are using HiFive Unleashed Expansion Board from Microsemi as this will hang the board. Hard reset will be required.

2. If Xfce4 desktop disk image is used with HiFive Unleashed Expansion Board and GPU then rebooting is required after the 1st boot.

2020.05.00

• All layers (openembedded-core, meta-openembedded, meta-riscv) updated to their latest revisions
• Kernel updated to v5.6.12.
• U-Boot updated to v2020.04.
• Notable new packages added: dtc and pcimem.
• openembedded-core now requires GCC 6 or higher on the host system. README has been updated with information on how to install the official openembedded-core build tools or build your own. Pre-built build tools from the same release source are also attached in the assets below.

2020.04.00

• All layers (openembedded-core, meta-openembedded, meta-riscv) updated to their latest revisions
• Kernel updated to v5.6.2
• GCC updated to 9.3.0
• Added back 3 packages removed in 2020.03.00 due to Python 3 migration (two Xfce4 packages and fio)
• ATI drivers updated (for HD6450 and similar GPUs)
• AMD drivers added (tested with RX550 and RX570, POLARIS GPUs)
• Glamor (2D acceleration using GPU) enabled (tested with HD6450 and RX550, no artifacts)
• Wayland distribution feature disabled as we use X11
• LLVM updated to 10.0.0 (final release, only used by Mesa for GPUs)
• Mesa updated to 20.0.3
• Vulkan enabled for AMD GPUs (tested with RX550)
• spidev driver enabled
• Disk images no more include debug packages by default and thus there is less to download
• Separate disk image with debug packages can be built by adding -debug prefix to the build target (e.g. demo-coreip-cli-debug or demo-coreip-xfce4-debug)
• Notable new packages added: libgpiod, libgpiod-tools, libgpiod-dev, i2c-tools, spitools, glibc-utils, libgomp-dev.
