In the default development process,the bootloader load firmware(elf) from the address just after the sof file,because the bootloader can calculate the size of sof file.The default development process can be used to develop factory image(include sof and elf file and sof file offset in EPCS is 0x0).For user image(the sof and elf file offset in EPCS is user defined) you can use the bootlaoder generated by programe which download from the alterawiki.

In default development process, the"--after" option can make the flash file generated from elf have an offset in EPCS, the offset is the size of sof file. flash file contain the address infomation in it's formate.
