I would like to use objcopy to generate a raw binary file so that I can load it directly into memory. However, the following objcopy command gave me a huge file.

objcopy -O binary file.elf file.bin

What is the right options to use?
Please note that the elf file is for MIPS 3000 core and the "Entry point address" is 0xbfc00000. (I used --set-start= option and it did not seem to help)

Any tips would help. Thanks.

[linuxpc ~]$ readelf -h file.elf
