    Hi gerger,

    if u've used the flash programmer in IDE, it automatically adds a boot loader program, in front of your code, if your reset address is in flash space while your program memory (a setting in library project properties) is in another memory space.

    The sources are in <nios2_root>/components/altera_nios2/sdk/src/boot_loader_sources. The IDE actually uses SRECs in <nios2_root>/components/altera_nios2...one for EPCS devices and another for CFI flashes.
