Typically, a Linux-based system has the following structure of volatile memory. The first section is filled with a Linux kernel loader, which in turn can be executed in several stages. For example, a small-size bootloader is copied to the CPU internal memory, performs initialization of external memory and copies the second-level loader to the external RAM. The second-level loader (for example, U-Boot) copies the Linux kernel to RAM and hands over control to it. Finally, the system launches custom applications stored in the last section of the Flash memory. So obviously, it's necessary to update the memory sections with user applications and the OS kernel.
