W25Q128 SPI FLASH can not boot correctly

[CVYang]

i use w25q128fv spi-nor flash as the boot media. i modified the bussinesscard.dts file "w25q64 to w25q128" and modified the spi-nor-ids.c SEC_4K to 0. and then make.
i can use the sunxi-fel write the flash.bin to the card, but it can not detect the SPI FLASH.
when i use sunxi-fel spiflash-info, it seems look "NO SPI FLASH DETECTED"
PLS！！！
