I usb LINFlexD_UART_MPC5744P testing the board of DEVKIT-MCP5744P. It's can send message to PC terminal, But MCP5744P can not get the message from PC termianl. I find the program beed locked on the line of "while (LINFlexD_1.UARTSR.B.DRFRFE == 0)". I add some judegment statement, as shown int the following figure. I find the timeout bit been set. How to solve this problem? anyone can help me? Thanks.
