What happens during the boot process after the Raspberry PI is turned on? I know that it differs from the standard Linux boot process ( no complex boot manager like Lilo/Grub ), I also know that the boot process has several steps, the device loads files like loader.bin, bootcode.bin, start.elf, kernel.img... But what is the exact order of these steps?

There is a boot manager; it is incredibly limited and only loads the files in a predefined order and can only deal with one operating system.– Alex ChamberlainJul 22, 2012 at 14:18

No boot manager like Lilo or Grub. I've rephrased the question.– asalamon74Jul 22, 2012 at 15:32

There is a boot loader, called Blob: elinux.org/Blob– dash17291Oct 25, 2012 at 13:48

As said here the boot process:
- GPU Core
- first stage bootloader, which is stored in ROM on the SoC
- bootcode.bin (loader.bin merged)
- start.elf
- config.txt
- cmdline.txt
- kernel.img
After this boot scripts will be called by the kernel: systemd or init

1Additional info: The kernel is then loaded and the rest of the boot process is handled by
initorsystemd.– JivingsJul 22, 2012 at 18:34 -

loader.binis not used anymore. It was integrated intobootcode.binand removed. Oct 8, 2012 at 6:46 -
