nano login: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
