The user manual for my board <A href="http://www.nxp.com/files/32bit/doc/user_guide/MX53UG.pdf" title="http://www.nxp.com/files/32bit/doc/user_guide/MX53UG.pdf">http://www.nxp.com/files/32bit/doc/user_guide/MX53UG.pdf</A> says to test uart by entering: echo “test” &gt; /dev/ttymxc2 on the device.&nbsp; I assume the result of that should be seeing "test" on my PC?&nbsp; That doesn't happen.&nbsp; Nothing appears to happen in fact.&nbsp; Further, I don't see how I can send a command to the device.&nbsp; I would really love to have a terminal interaction on my PC with the board.&nbsp; Is that possible?</P></BODY></HTML> Sat, 21 May 2016 16:57:09 GMT https://community.nxp.com/t5/i-MX-Processors/How-do-I-use-UART/m-p/491179#M78821 jonathantaylor 2016-05-21T16:57:09Z Re: How do I use UART? https://community.nxp.com/t5/i-MX-Processors/How-do-I-use-UART/m-p/491180#M78822 <HTML><HEAD></HEAD><BODY><P>I figured out reading the data at least!&nbsp; The baud rate was simply not right.&nbsp; Instead of using 9600, as is the documented default, I had to use 115200.&nbsp; Then I could read the output as it boot!&nbsp; Thank god.&nbsp; There's something at least.&nbsp; I still don;t know if I can have an interactive session though?</P></BODY></HTML> Sat, 21 May 2016 19:35:46 GMT https://community.nxp.com/t5/i-MX-Processors/How-do-I-use-UART/m-p/491180#M78822 jonathantaylor 2016-05-21T19:35:46Z
