Embedded Linux Booting Process (Multi-Stage Bootloaders, Kernel, Filesystem)

In this video, we will look at how the BeagleBone Black boots into an embedded Linux system. We will understand how the ROM Bootloader works for the AM335x SoC series, the first and second stage bootloaders (SPL/MLO and U-Boot) and how to load the kernel, device tree, filesystem and user space processes.

[@kushal8118]

really great video, if possible explain how DDR sets up and what all steps involved in future. These kind of explanation is very rare to get online. Also explain secure boot and what exactly kernel does before launching filesystem or init process. That's the core part which would give more information about the system. All the best and thanks for such a great video again.

Having MLO as first stage bootloader, one reason could be of processor mode switch from Real Mode to Protected Mode. It happens in x86 based processor but not sure about ARM chips

Awesome explanation... And so clear...

[@rajcodes100]

Sir - so if I have a board I need to load some files into the sd card before starting all of this process? I see that ROMbootloader immediately goes checking for MLO.That means MLO has to be pre loaded in the sd card .
