I am trying to print a char 'a' via uart3 in Tower k53n512.But after configuring the setting and baud rate still i am getting a wrong output at console..i have attached the nxp given code and the error photo..
please take look the attached project
Real term shows a error:UART framing error with some junk people coming along with some delay..
