Whats up everyone, welcome to the third part of bootloader development mini-servies. In todays video we gonna load kernel from memory and setup cross compiler so that you we can use C to program the kernel. If you didnt watch part 1 and 2 definitly do that before continuing and subscribe so that you dont miss any new videos.
