Beaglebone Black 的 ubuntu 核心 webdm alpha 无法启动

  • 772

我已经尝试使用“Ubuntu Core WEBDM”映像为 Beaglebone Black 闪烁 SD 卡，即“ubuntu-core-WEBDM-alpha-02_armhf-bbb.img”，如此处步骤中所述。

但是系统没有启动。我在串行控制台中捕获了以下错误。提前感谢您的建议和帮助。

从控制台：

Net:   <ethaddr> not set. Validating first E-fuse MAC

    uEnv.txt（在你的 SD 卡上）似乎是错误的。改为${bootpart}，${mmcdev}:${mmcpart}即

    # where to load initrd
initrd_addr=0x88080000
# load Snappy environment and call into Snappy boot after processing this file
uenvcmd=load mmc ${mmcdev}:${mmcpart} ${loadaddr} snappy-system.txt; env import -t $loadaddr $filesize; run snappy_boot

    这应该修复错误“文件未找到 snappy-system.txt”并允许 U-Boot 继续。
