Software Usage

• rz -> upload files
• littlevgl_demo

Setup

• Change params in build/env.sh and build\config\env-tf.sh
• source env-tf.sh
• _IMG_SIZE — 生成的镜像大小（越大，根文件系统剩余空间越多）
• _P1_SIZE — 给第一分区划分的大小（以 M 为单位）

Pack

• ./pack_tf_img.sh

Operationas

• write_all.sh — 为tf卡创建全套内容
• write_flash.sh — 为spi-flash写入全套内容
• write_dd.sh — 以dd镜像的方式写入全套内容（规定了分区信息）（生成方式见下一节）
• write_boot.sh — 向tf卡dd进Uboot
• write_mkfs.sh — 单纯的为两个分区进行硬盘格式化
• write_p1.sh — 单纯的向第一分区写入设备树内核等
• write_p2.sh — 单纯的向第二分区写入rootfs
• clear_partion.sh — 擦除分区表
• write_partion.sh — 写入分区表
• write_swap.sh — 增加swap
