我刚刚买了beaglebone green 之后升级官方的最新镜像,升级完成后发现无法通过u***模拟网络了,无法通过ssh登录。之后插上网线发现也不能识别,请问这该怎么解决?我通过串口打log看到系统升级应该是成功了,log中会打出下面的错误:
fsck: error 2 (No such file or directory) while executing fsck.ext4 for /dev/mmcblk1p1 fsck exited with status code 8 过一段时间系统还是可以起来。 我用ifconfig查看,发现eth0没有ip地址,显示如下: eth0 Link encap:Ethernet HWaddr 98:5d:ad:35:25:a6 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:5 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:418 (418.0 B) Interrupt:173 请大家帮帮忙,谢谢! 详细log如下所示; U-Boot SPL 2017.03-00002-gd12b1519b4 (Mar 14 2017 - 10:28:26) Trying to boot from MMC2 U-Boot 2017.03-00002-gd12b1519b4 (Mar 14 2017 - 10:28:26 -0500), Build: jenkins-github_Bootloader-Builder-532 CPU : AM335X-GP rev 2.1 I2C: ready DRAM: 512 MiB Reset Source: Power-on reset has occurred.
