X86下vxworks的romStart分析：

vxworks 压缩型BOOT的romStart分析：

binArrayStart：压缩的二进制image的起始地址

binArrayEnd：压缩的二进制image的结束地址

压缩的二进制image中没有romInit.o和bootInit.o

将ROM_OFFSET(binArrayStart)开始解压RAM_DST_ADRS地址，即RAM_HIGH_ADRS地址，

然后直接跳转到usrInit().

下面这段拷贝，具体含义是：

/*

* copy text to uncached locations to avoid problems with

* copy back caches

* copy the entire data segment because there is no way to ensure that

* binArray is the last thing in the data segment because of GP relative

* addressing

*/

知道可以说一下！呵呵

((FUNCPTR)ROM_OFFSET(copyLongs)) (ROM_TEXT_ADRS, (UINT)romInit,

((UINT)binArrayStart - (UINT)romInit)/ sizeof (long));

((FUNCPTR)ROM_OFFSET(copyLongs))

((UINT *)((UINT)ROM_TEXT_ADRS + ((UINT)BINARRAYEND_ROUNDOFF -

(UINT)romInit)), (UINT *)BINARRAYEND_ROUNDOFF,

((UINT)wrs_kernel_data_end - (UINT)binArrayEnd) / sizeof (long));
