fastboot：找不到命令

如果按照如下方法设置adb后：
ADB function
Download the Android SDK.
Update the adb configuration to scan for freescale's pid:
Run the SDK's tools to generate a configure file:

android-sdk-linux_86/tools/android update adb

Modify the files:~/.android/adb_usb.ini, to add freescale vendor id:

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x0bb4

Create a new udev rule file under the PC's /etc/udev/rules.d/ named: imx-android.rules. And fill in the following line into the file:

SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"

Change the new udev rule file's permission:

chmod a+r /etc/udev/rules.d/imx-android.rules

Connect the Android Device
Restart the adb server
            adb kill-server
            adb start-server
fastboot命令还是不能用，则需要考虑是否有fastbot这个可执行文件是否存在。
一般fastboot可执行文件放在/usr/bin目录下。
