应用背景 应用于开发智能家居和白色家电WIFI互联，完整的SDK 源碼，比如：空调，冰箱，以及电暖设备，LED照明，设计简单方便，为工程师开发节约时间。 关键技术 完整的SDK源码，可以快速移植在其他平台，工程师开发串行透明传输标准的API，全部OPEN SOURCE，应用的开发的成本低，效率高。

u-boot 在s3c2443上的移植,讲解在移植过程中的一些方法和需要注意的地方。-u-boot in s3c2443 the transplant, the transplant process to explain some of the methods and need to pay attention to place.

sst89c58下载器，使用keilc51的debug调试器下载。将本程序编译后写入sst89c58，并编程为remap 4kbytes。该芯片即有了keil环境下载功能,当p1.0拉低时，启动时进入下载程序，进入下载程序后将会自动删除block0,p1.0高电平时进入用户程序。 进入下载程序后，可以通过串口和keil的仿真环境连通，波特率自动调节,选择load HEX文件，即可将程序下载到sst89c58的低端32keeprom中。除了7e00-7fffh被占用-sst89c58 downloader, use the debug keilc51 Debugger download. This procedure compiled into sst89c58 and programming to remap 4kbytes. The chip has Keil environment that is the ability to download, p1.0 down, start the download entered into the download will be automatically deleted after block0, p1.0 to I enter the user program. After entering the download, through serial and Keil simulation environment connectivity, baud rate adjusts to choose load HEX documents, procedures and can be downloaded to the lower end of 32keeprom sst89c58 China. Apart from 7e00-occupied 7fffh
