JSCC iMX51 XBEE_DIN doesn't work

Hi,
I’m trying to use the XBEE socket at JSCC iMX51but when tried to send the frame, I don’t receive any answer.
The program has been tested on my computer before and is working well.

The jumpers J30 and J31 is setting in the position 1-2 and the receiver part is working on the CC iMX51, also the write function return the frame has been sent.

Do I have to configure something else in the kernel to use the XBEE_DIN?

Regards
Rafael

I think you need to ask that question on FreeScales web site.
