Methods of Trim and Transplantation of Embedded Linux Kernel

Linux operating system as an embedded system is widely applied in recent years, there is a big advantage for Linux system to apply in embedded products, it is plentiful in resources development and lower cost. Load the root file system is important to the operation of the kernel during startup, and it also an important part of the embedded system.
