or connected to RS232 driver.

So, it must be a programming issue? Not hardly.

it should not be programming issue, The same codes run well on ATMEGA2560.  There should be a bug with arduino  ATMEGA644 SDK

If you have a real atmega644, and not a 644a or 644p, then I think that in fact it only has one UART!

Yup, only the larger AtMega1284 from that series has two UARTs.
