Hi,
I have a Beagleboard rev B board, and its not showing any output on terminal.

I have tried minicom on linux(KUbuntu), Teraterm and hyperterminal on windows, but i am not able to get any data on screen.

I have tried that on 3 machines, have double checked the cables and the settings but the problem is same, no output. what should i do.

I suggest you read the System Reference Manual. There is a section that takes you step by step to make sure you have the correct ribbon cable and null modem cable.

If this all checks out, then you need to request an RMA. There was an issue on early Rev B boards where the level shifter would fail. This was fixed on Rev B6 and later boards.

What I found was that ALL of my DB-9 / dual-row header ribbon cables
were not wired the right way.
They were all the common crimp-on DB-9 and crimp-on dual-row header.
You just can't get there from here.

Please see the following for a very clear description:

What does NOT work is this one:

Correct. You cannot use the Intel version. You must use the Everex version. This is spelled out on the System Reference Manual.
