Today, after compiling the kernel and burning the file system of qt4.5, an error occurs. When the system runs on the top, it gets stuck. After searching, it turns out that there is a problem with the Kernel configuration.

In fact, at this time, the kernel has been started normally, but an error occurred when starting the shell. This problem occurs only when the IOCTL call of the system has not been returned.
After finding some documents on the Internet, we found that nwfpe math emulation (in the floating point emulation item) was added to the kernel compilation option.
