刷机方法

暂无免拆机刷机法，必须要拆机引出USB进行线刷

刷机工具：https://pan.baidu.com/s/1aOAIZ3vyG8mgipj726Bhgg 提取码: 7eee
固件发布：https://github.com/hanwckf/build-beikeyun/releases/latest

准备工作

1. 去Github Release下载你喜欢的固件，解压xz包得到img镜像

2. 剪一根废旧的USB线，焊接到USB焊盘上，或者焊接一个排针在焊盘上，注意线序（可以从背面焊接，VCC可以不焊）

3. 进入maskrom模式

• 对于已经刷过第三方固件的机器，可按照本文后面的方法快速进入maskrom模式
• 对于从未刷机的原厂固件，按照以下步骤操作以进入maskrom模式：将USB线连接到电脑，然后用镊子短接主板背面的maskrom触点，最后再接入12V电源，等待两秒钟后松开镊子。

4. 下载安装线刷驱动 (DriverAssitant_v4.5.zip)和AndroidTool，然后运行AndroidTool，如果没有出现"发现一个MASKROM设备"的提示，请重新进行准备工作

选择img镜像刷入即可（loader已经预先设置无需更改）

5. armbian默认root密码为1234，第一次登陆后会让你设置新密码

其他注意

已经刷入Rock64的armbian固件后，可以在上电时长按主板正面的微动开关进入maskrom模式而无需短接触点，此时ttl输出如下（波特率：1500000）：

entering maskrom mode...

对于已经刷入任一第三方固件的机器，可以采用以下方法进入maskrom模式：
接好TTL（波特率：1500000），上电后在U-boot倒计时结束前按任意键进入U-boot命令行，输入以下指令擦除emmc前面的内容：

mmc erase 0 100

然后复位

reset

复位后就进入maskrom模式了
