I figure out the difference. When executing "make" command， I should do it like this:

make CODE_BASE=0
Then the generated code in boot_loader_epcs_sii_siii_ciii.elf will start at address 0x0. Now by virtue of this command
elf2hex --input=obj/boot_loader_epcs_sii_siii_ciii.elf --output=kernel_epcs_boot_rom_synth.hex --width=32 --base=0 --end=0x3ff --record=4 --lower
the required boot loader code file(i.e. the .hex file) will be generated.
