针对Simplicity Studio 4，使用串口命令擦出Flash里面存储的OTA image文件
Platform：Simplicity Studio 4、EmberZNet SDK 6.4.1.0
【SPP】Content：
有时候在使用EmberZNet协议栈对设备做OTA升级测试的时候，flash一块区域会存储着我们的镜像文件，当从新下载不同固件版本的文件时，会因为OTA自检到FLASH存在不同版本的IMAGE文件而自动升级到之前的版本，故在此情况下就需要擦出一下之前保存的image文件；
本次实现使用串口发送0x64的时候，实现擦除，在串口回调添加下面代码，打开协议栈串口打印：
boolean emberProcessCommand(int8u *input, int8u sizeOrPort)
{
int8u dat;
while (EMBER_SUCCESS == emberSerialReadByte(sizeOrPort, &dat))
{
if (100 == dat)
{
EmberAfOtaStorageStatus status;
emberAfGuaranteedPrint("[1:app]Enter the wipe out function\r\n");
status = emberAfOtaStorageClearTempDataCallback();
emberAfGuaranteedPrint("[2:app]status=%d\r\n",status);
}
}
return FALSE;
}当串口发送完0x64后，打印：
