I use MCBTR9 Board, the serial interface works in the ordinary system, but if the system is integrated with task(RTX), then it does not work. could you please advise me, what i do.
I suppose your example code for the UART of the MCBSTR9 works. have you remembered to initialize your UART before any task attempts to use it?
yes i initialized the UART0.
* verify connection settings (baudrate, stop bits...) * test TX line with scope to verify no signal * can you run your application in the simulator?
