	*5.apt-get update		*4. 添加DNS: echo ‘nameserver 8.8.8.8’ >> /etc/resolv.conf
	*6.~~then you can fetch and install any packages from ubuntu by using apt~~-~~get~~.		*5. apt-get update
			*6. 然后你就可以通过apt-get安装软件包了.

	6.~~Furthermore：~~		6.更多：

	~~Some functions are not available on the W2 now~~, ~~because the kernel is not fully functional~~, ~~we are working hard to make it more and more complete~~, ~~please follow our official website update~~.		一些功能在W2上面暂时无法使用, 因为kernel仍然在开发中, 我们正在努力完善W2的功能, 请多在论坛上多留意W2的信息.

	2.~~Write the bootloader to the Banana Pi~~ W2 flash:		2.将bootloader写入到 W2 flash:

	~~Banana Pi~~ W2 ~~board can boot from~~ EMMC flash or SPI flash ~~on the board~~, ~~the difference is the location of the~~ bootloader, ~~so if you will not participate in the development of u~~-boot, ~~this will not matter to you. So here is how to write bootloader to EMMC~~.		香蕉派 W2 可以从 EMMC flash 或者是 SPI flash 启动, 区别在于bootloader的位置不同, 接下来介绍如何把 bootloader 写入 EMMC, 如果你不准备开发u-boot, 则不必关心这个.

	~~Normally the W2 board you got had been programed in the factory~~, ~~but if the version of the bootloader isn’t the latest one~~, ~~I recommend you to program it by yourself again. The latest version of bootloader is available on the Banana Pi website~~.		通常见到的 W2开发板, 工厂已经提前烧录好bootloader了, 但是如果bootloader的版本不对, 这里你可以按照以下步骤自己烧录.

	~~Requirement~~:		要求:

	*1.~~A windows PC runs serial terminal tool like hypertrm~~. (~~I recommend using~~ “hypertrm”, ~~because other tools sometimes fail to transmit data~~);		*1. 首先需要安装一个PC端的串口工具, 如：hypertrm. (这里我推荐使用 “hypertrm”, 因为其它工具数据传输可能失败);
	*2.~~Latest version u-boot binary file from Banana Pi website~~ (dvrboot.exe.bin);		*2. 下载uboot二进制文件(dvrboot.exe.bin);
	*3.~~A hardware configuration binary file for W2 （RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866_padding~~.bin);		*3. 下载 W2硬件配置二进制文件（RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866_padding.bin);

	~~Steps~~:		步骤:

	*1.~~Connect the serial port between the host and the board correctly~~, ~~run the terminal software and set up the relevant parameters~~ (115200, 8N1, none);		*1. 通过串口将 W2开发板与PC连接, 然后运行终端软件, 设置串口参数 (115200, 8N1, none);
	*2.~~press~~ “ctrl+q” ~~then to power on the board~~, ~~and when the screen appears’~~ d/g/r '~~, it can be released~~;		*2. 按住 “ctrl+q” 然后重启开发板, 当终端界面出现’ d/g/r ' 后就松掉;
	*3.~~Input~~ “h” ~~and send hardware configuration binary files~~ (RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866_padding.bin) in Y-modem ~~mode on the terminal side~~.		*3. 输入 “h” 然后发送硬件配置二进制文件 (RTD1296_hwsetting_BOOT_4DDR4_4Gb_s1866_padding.bin) 在 Y-modem 模式.
	*4.~~Wait for the transfer to complete~~, ~~then input below in console~~:		*4. 等待传输完成, 然后输入下面的参数:
	s98007058		s98007058
	01500000		01500000
	*5.~~Input~~ “d” ~~and send u-boot binary files~~ (dvrboot.exe.bin) in Y-modem ~~mode on the terminal side~~.		*5. 输入 “d” 然后发送uboot二进制文件 (dvrboot.exe.bin) 在 Y-modem 模式.
	*6.~~Wait for the transmission to complete. Enter~~ “g” ~~then the u-boot will be programed to the EMMC automatically~~.		*6. 传输完成后, 输入 “g” 然后uboot将被自动烧录到eMMC.

	3.~~Make a ubuntu root file system for W2 on a ubuntu PC~~.		3. 在Ubuntu PC上面制作一个根文件系统.

	Ubuntu ~~has the version for~~ arm64 ~~architecture~~, ~~it’s suitable for the Banana Pi W2~~, ~~most of packages built by ubuntu for arm64 can run on the W2 board~~.		Ubuntu 架构是 arm64, 适用于W2, Ubuntu上面大多数的arm64软件包都适用于W2.

			* http://forum.banana-pi.org/t/bananapi-w2-ubuntu-18-04-new-image-release-2018-09-17/6790

			2.在你的Ubuntu系统电脑上安装bpi-tools, 执行以下命令即可安装：
			* apt-get install pv
			* curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools \| sudo -E bash

			3.下载完镜像后, 插入TF卡到你的Ubuntu电脑中
			* 运行命令 "bpi-copy xxx.img /dev/sdx" 烧录镜像到你的TF卡中.

			4.烧录完成后, 把TF卡插到W2中, 按住W2的电源键启动W2.

			====在SD卡上制作bootloader====

	~~===Build your own image on W2===~~		由SW4控制, W2有两种启动方式
	~~====How to make a SD card with bootloader====~~

	~~there are two ways to boot w2~~, ~~controlled by SW4~~

	[[File:Bootsw4.jpg]]		[[File:Bootsw4.jpg]]

	*0 ~~boot from~~ emmc.		*0 从 emmc 启动.
	*1 ~~boot from~~ SPI + SD ~~card~~.		*1 从 SPI + SD 启动.

	~~After power on, there are 3 steps must be done before loading kernel,(Normally they all are called bootloader):~~

	*step 1: CPU init - the code is inside CPU;
	*step 2: init the flash device on which we boot from; (normally it’s called preloader)
	*step 3: u-boot;

	~~RTD1296 supports booting from eMMC and SPI flash~~, ~~so if we want to boot W2 from SD card~~, (that means we put u-boot on the SD card.) the second step code must be written to SPI flash, normally it’s done in factory before the board sending out, and the code is fixed and provided by RTK without source. We need not care about it, it does a simple job.		打开W2的电源后, 这里需要三个步骤来加载内核, 通常这三个步骤被称作bootloader

	~~In fact, if the board will boot from eMMC, the second code must be written to eMMC first too, remember that we introduced how to do it with~~ u-boot ~~together on other pages. Normally it’s also been done in factory.~~		*第一步 1: CPU 初始化 - 这份代码属于CPU内部;
			*第二步 2: 初始化我们要启动的Flash 通常这步被称作preloader
			*第三步 3: u-boot;

	~~The~~ u-boot ~~for eMMC and~~ SD ~~card are different~~, ~~normally eMMC u-boot 's name is~~ '''dvrboot.exe.bin''', ~~and u-boot for SD card name is~~ '''u-boot.bin'''.		RTD1296 支持从 eMMC 和 SPI flash 启动, 因此如果你想要从sd卡启动W2, (这意味着我们把 u-boot 放进 SD 中.) 第二步的代码必须要写到 SPI flash中, 通常工厂需要把这一步做好.
			实际上, 如果W2从eMMC启动, 第二步的代码需要写道eMMC, 请留意这里我们在介绍怎么烧录uboot, 通常这一步也是工厂做好.
			在eMMC和SD卡中的uboot是不同的, 通常eMMC的uboot名称为'''dvrboot.exe.bin''', SD卡的uboot名称为'''u-boot.bin'''.

	~~Write u-boot to SD card~~		把uboot写入SD卡

	~~The u-boot file for booting from SD card is here~~: https://drive.google.com/drive/folders/17ShSHLOvxeYA6tI9HQXOAb3O7RjqfD_6?usp=sharing		SD的uboot相关资料在这里: https://drive.google.com/drive/folders/17ShSHLOvxeYA6tI9HQXOAb3O7RjqfD_6?usp=sharing

	tftp 0x1500000 u-boot.bin		tftp 0x1500000 u-boot.bin
