用于Beaglebone Black的ubuntu核心webdm alpha无法启动
我已经尝试了用于Beaglebone Black的闪存SD卡和’Ubuntu Core WEBDM’图像,即’ubuntu-core-WEBDM-alpha-02_armhf-bbb.img’,如步骤中所述。
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: not set. Validating first E-fuse MAC cpsw, usb_ether Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc0 is current device SD/MMC found on device 0 reading boot.scr ** Unable to read file boot.scr ** reading uEnv.txt 237 bytes read in 12 ms (18.6 KiB/s) Loaded environment from uEnv.txt Importing environment from mmc ...

看来uEnv.txt (在您的SD卡上)是错误的。 将${bootpart}
更改${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“File not found snappy-system.txt”并允许U-Boot继续。
