Usually, the memory ing of large files is seldom used, and such a requirement occurs. Therefore, record the process and give you an introduction, because the application is not complex, you may not be able to think about it. For some small files,

Check the Code through several days of data query. The problem was finally solved. I use the au1250 chip and the falsh of k9f1208. It mainly reads the kernel file in the USB flash disk. Then replace it with the old file. To implement this,
