【Marvell ESPRESSObin】将系统移植到U盘

netlhx

实际使用过程中，发现系统有时会死机，怀疑是不是SD卡的问题，准备将系统移植U盘上，看问题是否还会发生。

将系统镜像文件写入到U盘中，系统镜像的大小为4G, U盘的容量为16G，空出来的部分考虑用来做文件共享空间。先写入系统镜像，如下



写入后上电，需要修改U-BOOT的参数，将原来的MMC替换为USB，如下

1. setenv bootusb 'usb start;ext4load usb 0:1 $kernel_addr $image_name;ext4load usb 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/sda1 rw rootwait; booti $kernel_addr - $fdt_addr'
   

复制代码

其实可以用下列的命令代替，效果相同

1. setenv bootcmd 'usb start; ext4load usb 0:1 $kernel_addr $image_name;ext4load usb 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/sda1 rw rootwait; booti $kernel_addr - $fdt_addr'  

复制代码

然后boot就可以了


然后启动，效果也挺好，贴一段启动画面

不过使用过程中发现OMV不能使用SDA2分区来做为外部存储空间，大概是为了将系统和数据分开来保存的考虑吧。
