For writing the data directly to the EEPROM using a USB-Blaster I use a .jic file. You can create a .jic file from a .sof file in Quartus via File > Convert Programming Files. Then you can put multiple image files, for instance a factory image and multiple application images, in 1 .jic file. In your case, you seem to write the EEPROM via the asmi core, so I assume you are trying to write a file with one image to a known location in the EEPROM. You cannot use .sof file format for that purpose. You need to use a .rbf file or a .rpd file, depending on the kind of FPGA you are using (you can create .rbf and .rpd files via the same tool, via Convert Programming Files). You can probably find which file you need in the documentation, or alternatively: you can first create a .jic file of your .sof file. Then you can create both a .rbf file and a .rpd file, and compare the contents to the .jic file, using a HEX editor (note that some of those files have an extra header). The file that matches the .jic file is the one you should use. Good luck!
