我们很荣幸地发布适用于 Colibri Vybrid 模块: Colibri VF61 和 Colibri VF50 V2.5 Beta 1 Linux BSP。

该版本包含:

      • U-Boot 2015.04 boot loader
      • Linux 4.1.5 LTS kernel

本次发布版本的主要更新有:

U-Boot:

  • Introduce m4boot command which accepts a FIT image to boot the secondary Cortex-M4 core
  • Add fdt_fixup variable to make it easier to include scripts which fix-up the kernel's device tree (e.g. for evaluation/testing purpose)
  • Set DDR fix property in the kernel's device tree to enable Suspend-to-Memory support

Linux kernel:

  • Update to 4.1.5 LTS long term stable Linux kernel
  • Initial Suspend-to-Memory support using Vybrid's LPSTOP2 low power mode ("echo mem > /sys/power/state")
  • Framebuffer ioctl WAITFORVSYNC which allows to synchronize buffer swap on vertical blanking period
  • Support RS485 transceiver on UARTs

Linux user-space:

  • Update to Angstrom 2015.06/OpenEmbedded fido/Yocto 1.8:
    • glibc 2.21
