SS928如何使修改加大文件系统容量

打包文件系统的时候设置文件系统大小，或者再创建一个文件系统分区在现在这个文件系统上挂载

将文件系统做大一些，然后devtmpfs tmpfs是内存空间和ubi0无关

我是采用整体编译的方式生成的镜像文件，是否有命令进行Linux命令后进行设置，还是在boot模式下可以用什么命令设置？

重新生成了一个rootfs_ss928v100_4k_256k_50M.ubifs重新烧入后。运行命令：
1、setenv bootargs ‘mem=512M console=ttyAMA0,115200 clk_ignore_unused ubi.mtd=2 root=ubi0:ubifs rootfstype=ubifs rw mtdparts=nand:1M(u-boot.bin),12M(kernel),50M(rootfs.ubifs)’;sa
2、setenv bootcmd ‘nand read 0x42000000 0x100000 0xC00000;bootm 0x42000000’;sa
reset后报错进不了系统：
