1-EasyARM i.MX287A开发板

翻到了一块旧的ARM9开发板，主控是ZLG imx287，这里重新玩一下它

开发板资源

开发套件支持 NAND Flash、TF 卡、USB 三种启动方式，可通过跳线进行设置

关闭根文件系统写保护
进入 uboot 后，打印环境变量，找到 bootargs 参数信息。将 ro 改为 rw 即为可读可写

bootargs=gpmi=g console=ttyAM0,115200n8 ubi.mtd=5 root=ubi0:rootfs rootfstype=ubifs ro

setenv bootargs gpmi=g console=ttyAM0,115200n8 ubi.mtd=5 root=ubi0:rootfs rootfstype=ubifs
rw
