You could know the chip ID W25Q32V

861110859

Because W25Q series chips, majority is your own custom manufacturer, ID have a lot of different, the need to add, tutorial area have to add the chip detailed tutorial, if not, please capture, speaking, reading and writing of related images, made clear the chip and the ID.

If you have the RT809F, want to know the ID of the chip, it is a very simple thing.
To play with parallel port, however, does not make sense.

他的意思是RT809F 能不能读写 UNIQUE ID ，我j觉得这个功能很重要，现在很多机你必须用原装芯片不可以换芯片为了你开机时候 CPU先确认SPI 芯片的 UNIQUE ID 如果你用其它的芯片写对的程序也开不了为了UNIQUE ID 不是原装的

这个问题，老大以经搞定了，有些芯片，如W25Q32V，使用了OTP编程，与QPI总线编程。809F在读取这些芯片时，会自动保存QPI总线状态寄存器的数值，你使用新芯片写入数据时，选择这个芯片的OTP方式编程，载入数据时，选择要烧写的数据+ 自动保存的QPI总线状态寄存器的数值 文件一同载入，即可！
