A novice looked at the s3c2440init.s startup code and summarized it as follows:


1. Turn off the watchdog


2. Turn off all interrupts


3. Set the clock frequency


4. Initialize SDRAM


5. Initialize the stack in each mode (except user mode)


6. Copy the data segment and clear the ZI segment


7. Jump to main.c to execute the main function



I have carefully read the code of the .s file and the general process is as follows. If there are any errors, please let me know.
