Hi there,

I started with u-boot and now try to get a general understanding of how it is organized. I use a devkit8000 so my work is mostly specific to that board. I tried to find the path the u-boot takes to bring up the system. These are my findings:

arch/arm/cpu/armv7/start.S - Startup code - Jump to board_init_f

arch/arm/lib/board.c

board_init_f()

- Is run from flash - main purpose is to initialize RAM - call: relocate_code

arch/arm/cpu/armv7/start.S

relocate_code

- copies the code from low addresses to high addresses

arch/arm/lib/board.c

board_init_r()

- call: board_init

board/timll/devkit8000/devkit8000.c

board_init()

arch/arm/lib/board.c

board_init_r()

- inits a bunch of systems. What is initialized is defined by defines - enters the main_loop which shows autoboot msg and/or console

So my question is: Is this correct? Did I miss something important?

Thanks! Simon
