RS-232 communication link...

Hello,

We are trying to establish the communication link between the Beagle board (as host device) and slave devise(some ADI DSP board) using the UART available on the beagle board. We are sure both physical ports of the beagle and salve(DSP) are working fine. But due to some reason we are unable to get the echo back to host Beagle terminal.

We are using the angstrom Linux running on Beagle. It seems we can’t see minicom on Beagle(as host) we can’t open the minicom terminal and do basic testing. We used one of the applications which can open up the port on Beagle and send the data to slave and echo back but it is not working. Same application works from the actual Linux PC to DSP.

Do we miss any thing while establishing the communication b/w Beagle and slave device?

Can you please suggest or provide us the application which works for Beagle as host and can communicate to slave device over UART?

Also can we have minicom on Angstrom Linux?

We appreciate your help!

Best regards,

Kishore.

I'm using Lua library luars232, but there's some Python library available
also. It's easiest way for prototyping and testing.

Also can we have minicom on Angstrom Linux?

Yes, there's recipe for minicom, so maybe you just need to dpkg install it.
And you can always bitbake it yourself.
