33-iFix团队10月26号现场培训课程分享（七）

控制台命令是智能主板维修必须掌握的知识点，也是必备利器，掌握这个知识点可以让你的维修过程事半功倍。

控制台分BootLoader控制台和安卓控制台，这个概念一定要分清楚，BootLoader控制台下可以执行擦空、强制升级、DDR自检、存储容量查询、串口打开关闭等。

安卓控制台下最常用的就是屏参修改，这也是换屏的维修师傅比较喜欢的知识，因为换屏时，很多时候都没有一模一样的原装型号屏，基本通过代换完成，代换后由于屏厂家和参数可能不一样，出现花屏、倒屏、灰屏等。都会做后期调试，比如改逻辑板，边条等，当然也有很多是改硬件不能完成的，掌握安卓控制台改屏参，就会有更多代换可能性。

也有一部分是自己误调试引起灰屏，或者换板时内置屏参本身不匹配引起的灰屏都会用到这个知识点，在一文中对MSD6A818芯片方案做了一个介绍，大家应该有一些共鸣。

我们先来看看几大芯片厂家控制台进入方法：

下面我们先聊聊BootLoader控制台下的几个方案常用命令。

一、Mstar

1、擦空 ，在Mstar方案里，有三种组合，Nor+Nand，Nor+EMMC，单EMMC，针对Nand和EMMC的擦除命令有点区别，但是擦空的时候一定要注意，工厂提供的U盘升级软件是不是支持空片烧录，如果不支持，那么你就好好的哭一场吧，擦空后你会发现再也不能升级了，或者怎么升级也生不好，不过对有RT809H的维修工程师来说，这不是什么大事，只要擦除之前对Nand或EMMC做一个5%左右的备份就可以了，擦除后再写入5%。

当然对拥有RT809H的用户都会会心一笑，可以用编程器直接擦呀，而且编程器自带擦空功能可以对一部分EMMC有修复功能。

Nor+Nand：nand erase；nand scrub。

Nor+EMMC：mmc erase。

单EMMC：mmc erase。

2、升级， 升级是我们比较常用的一个命令，在Mstar方案中，不同的组合结构，不同的升级文件名，升级命令都不一样，例如6i48的命令有

usb reset

ustar

这个命令是针对U盘升级文件为nand、script两个文件夹的，并不是所有MSD6i48都一样，同时U盘升级文件要支持空片烧录，不然只有用网线升级。

控制台下显示命令行格式为下图。

上图就是输入usb reset后没识别到U盘的一段打印，不同的主板设计的U盘升级口不一样，这个要注意，这时候就要检查U盘是否插入升级口，U盘是否正常被识别。

上图为正常识别到U盘的打印信息，这时候才能继续输入升级命令。

输入升级命令ustar后回车，升级软件正常就会监控到升级打印进度。

上图是早期的网络电视机主板升级命令，再例如早期的智能机MSD6A801芯片方案，用第一批乐视S40/S50举例，升级文件名为bin格式，

升级命令为uup或者usb_check_bin都可以。

后期的MSD6A628和MAD6A918开始一直到现在，升级文件名均为bin格式，升级命令为更简单的"cu"，一定要小写。

在升级过程中，可以看到打印信息提示所需文件名（如下图），如果文件名错误是升级不成功的，所以遇到升级不成功需要检查U盘内的文件名是否与打印信息提示文件名相符。

3、打开串口，在我们维修Mstar方案的主板时，经常会看到串口关闭的打印，这种串口关闭的打印比较明显的标志就是 UART BUS OFF!! 串口关闭很是令维修人员头疼，因为它被关闭后，将看不到所有的打印细节，也就看不到引导是否运行完整，主程序是否加载正常。

如果想看到这些细节来分析故障点，那么就要串口必须打开，串口关闭分两种情况，一种是能进控制台，一种是不能进控制台。能进控制台的只需要输入串口打开命令就可以了，下面我们以TCL MS828板举例。
