You command line is incomplete, no mentioning of the -drive at24. The
intended usage is:
-drive file=/path/to/image,if=none,id=eeprom -device at24,drive=eeprom
You can also specify the desired at24xxx type explicitly, e.g. at24c256
for the 256K model. Otherwise the type is derived from the image size.
