雄迈AHB-7804T-LMS系统烧写

淘宝买了块板子，里面有各种sdk，什么localsdk、netsdk，然而对于我来说，并没啥用。它的文件系统我又进不去，遂决定重烧系统。
在音频接口的前面有三个孔的端子，分别是R、T、D。
焊接插针，一开始D没焊好，虚焊了，有接收没输入，差点以为被锁死了，不能重烧写。后面被一网友提醒了下，遂重新检查了，发现果然有问题，重新焊接了，果然好了。
原装板子的uboot打印是这样的

后面就动不了了。
但你细心你就会发现这句话“Press CTRL-C to abort autoboot in 0 seconds8192 KiB hi_sfc at 0:0 is now current device”。重新上电，按着ctrl c，可以进入uboot，然后论坛上花了2百纳币下了个H3520Dv100的050的sdk，编译器是100nptl的。按照sdk中的全编译，然后按照《Hi3520D SDK 安装以及升级使用说明》中重新烧写系统，由于我的spi flash是8M，所以我将文件中的分布稍微调整了下，大小成倍缩小了而已。
最终，板子系统烧写成功
