Android system boot process

 Android system boot process:

1. Power Startup and System Boot: When the power button is pressed, the boot chip code is executed from a predefined place (solidified in the ROM). Load the bootloader into RAM and execute.

2. Bootloader: BootLoader is a small program before the Android operating system starts running, and its main function is to pull the system OS up and run.

3. Linux kernel boot: When the kernel boots, set the cache, protected memory, plan list, and load driver. When the kernel finishes setting up the system, it first looks for the init.rc file in the system files and starts the init process.
