Try things one at a time. You can't easily deduce which line is causing the problem. The output is buffered so sometimes its a bit difficult to correlate the cause of the problem with what actually makes it out the serial port.

Are you sure you are not reading from places in memory that are not in the EPROM? Try printing out the parameters to the EEPROM_Read2ByteSigned function.

Maybe the serial buffers are overflowing, are you checking the return values of printf?
