ZYNQ调试w25q128bv做flash启动系统
配置petalinux系统从flahs启动，发现BOO.BIN能启动，BOOT.BIN+image.ub启动不了。其中烧写和配置的时候，image.ub.bin偏移地址都是0x520000
烧写，然后启动

Zynq>一开始怀疑：uImage文件本身有错。错误原因可能是生成的时候出错，也可能是错误使用某个文件。参考文献说uImage是冲zImage copy过来，笔者也是这么做的。因此笔者怀疑是uImage文件错误用了zImage。在arch/arm/boot/下面还有一个uImage文件是在生成内核的时候产生的。
然后对比以前能启动的板子时候打印信息如下：
Hit any key to stop autoboot: 0
SF: Detected n25q128 with page size 256 Bytes, erase size 64 KiB, total 16 MiB

对比发现：
N25Q128和W25Q128 不可以相互替换，除非使用单线SPI通信，且只能使用F80000 ~FFFFFF或者0~7FFFF范围内的内存。 N25Q128的指令在不同spi模式（单线、双线、四线）下有所不同。
修改为：
再次烧写完，系统正常启动
