在NanoPi Neo Board上构建自定义Linux

时间:2016-08-18 11:19:43

标签: linux arm embedded-linux buildroot nanopi

我是为嵌入式主板构建自定义Linux操作系统的小伙子 - 所以请忽略我的无知。

我有一块名为NanoPi NEO的电路板,它有自定义Debian linux。现在该主板带有一个.img文件,可以闪存到SD卡上并插入插槽,然后主板从卡上启动。

现在我正在尝试构建自己的自定义linux并闪存到SD卡。我已经通过论坛和手册,并设法做到这一点。

问题

我知道自定义linux构建有三个组件

  • boot0 - 加载BootLoader的东西
  • U-Boot - 众多BootLoader之一。 (该项目使用此方法)。
  • Rootfs - 文件系统和其他所有内容。

董事会制造商的网站提供了these建立自定义操作系统的说明。我按照这些说明执行了所有操作,包括正确分区SD卡(前面有空闲空间用于boot0,启动分区用uImage和Script.bin,以及分区用于rootfs)

问题是电路板在启动时加载内核但是没有安装文件系统并证明用户提示。

这是Dmesg输出。

所以我猜问题是rootfs没有被检测到并正确安装。请指导我。

1 个答案:

答案 0 :(得分:0)

我很确定问题是linux没有在uart上激活控制台。

看看内核日志:

for(i in 2:number_data_frames){ merged_df <- merge(merged_df, list_of_dfs[[i]], by="UserID") }

http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/configure-kernel.html中所述:

  

当列出多个控制台时,输出将发送到所有控制台,输入将从最后列出的控制台中获取。最后一个控制台是Linux用作/ dev / console设备的。

因此,请尝试通过调优[ 0.000000] Kernel command line: console=ttyS0,115200 console=tty0 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait init=/sbin/init u-boot环境变量使console=ttyS0,115200成为最后一个(或唯一)console选项。

要检查此建议,只需“按任意键即可停止自动停止”,然后使用bootargs检查默认printenv内容,运行bootargs,最后运行setenv bootargs ... ... ... 。但是,请务必检查bootd以及它所调用的内容,因为其中一项内容可能会在bootcmd执行期间调用setenv bootargs并覆盖您的手动选项。

P.S。 bootcmd可能会被省略。
