I see posts about seeing console output via uart, but don't understand how that works. If I use putty, or hyper terminal (on Windows), I can connect to the device. My PC then receives unreadable garbage on the screen. Now what? The user manual for my board http://www.nxp.com/files/32bit/doc/user_guide/MX53UG.pdf says to test uart by entering: echo “test” > /dev/ttymxc2 on the device. I assume the result of that should be seeing "test" on my PC? That doesn't happen. Nothing appears to happen in fact. Further, I don't see how I can send a command to the device. I would really love to have a terminal interaction on my PC with the board. Is that possible?
Solved! Go to Solution.
I figured out reading the data at least! The baud rate was simply not right. Instead of using 9600, as is the documented default, I had to use 115200. Then I could read the output as it boot! Thank god. There's something at least. I still don;t know if I can have an interactive session though?
