You mean both the devices are configured to 9600 baud?

What will be reason if real BAUD rate is not matching to one set by source code ?

Here, the set values need to be re-checked. As per the formula in SCI section, the values of SCIHBAUD & SCILBAUD needs to be correct to obtain the required baud rate.
