On the AVR, a boot loader section of 256 bytes to 4 KB can be reserved in its flash. This code can perform any number of user-defined tasks, from setting up a serial link with a remote system, to booting from a remote image over Ethernet using PXE.
At its core, an AVR boot loader is no different from any other AVR application, except that when compiling it one extra linker flag is added to set the starting byte address for the boot loader:
--section-start=.text=0x1800
Replace this address with a similar one for the specific MCU that you're using (for AVR depending ...
