QCC300x --OTA步骤

在sink工程目录下创建一个目录，用来存放公钥和密钥，假设目录名称为<oem_for_ota>；

在该目录下创建两个python脚本，和自动生成ota文件，这里写成脚本文件，方便每次生成OTA生级包。

gen_key.py，用来自动生成密钥，内容如下：

Gen_ota.py，用来生成ota文件，该脚本会自动先搜索本地目录来查找目标xuv文件，若本地目录没有.xuv文件，则自动搜索父级目录，若找到则打包ota文件，否则报错退出。

其脚本内容如下：

import os, sys,time
os.chdir(os.path.abspath(os.path.dirname(sys.argv[0])))SRC_DIR = os.path.dirname(os.getcwd())+'\\'
CUR_DIR = os.getcwd()+'\\'
TOOL_DIR = 'C:\\ProgramFilesUser\\Qualcomm\\ADK_QCC300x.WIN.1.0.167\\tools\\bin\\'#
