After adding flags c_oflag=0 and c_lflag=0 and connecting grounds of both boards, the data was received on beaglebone!! It was able to transmit characters as well as a string.
Beaglebone side code:
https://github.com/cu-ecen-5013/final-project-atharvdesai1996/blob/master/writetobb.c
Tiva side code:
https://github.com/cu-ecen-5013/final-project-ruchaborwankar/blob/master/UART%20tiva%20and%20Beaglebone.zip
Output:-

Thus, UART communication established between TIVA and Beaglebone
