If one made the eruv with bread on day one, may he use different bread for the eruv on day two?

ShabbatEruvEruv Techumin

Synopsis

Using new bread for the eruv on day two requires a declaration (kri'at shem eruv) which constitutes forbidden hachana (preparation). Therefore, one must use the identical bread from day one; using different bread is invalid even b'dieved.
