[quote user="supreeth anil"]I think there are some timing/power up issues with ICDI hardware. Anyways I will test it further.[/quote]I think the problem might be that the neither the ICDI UART receiver or TM4C123GH6PM transmitter have a pull-up on the UART signals. At power-up the TM4C123GH6PM UART transmit signal may float to an indeterminate level causing the ICDI receiver to see the start bit of a character. The external RS232 converter might have a pull-up on the receive signal which avoids the problem.
