I need to set the expansion connector to access some signals of Beagle
c4.
To this I edit the u-boot release v2010.09 (http://groups.google.com/
group/beagleboard/browse_thread/thread/
5c3f3615de780018/8df71d9d5a957567?lnk=gst&q=daicav #
8df71d9d5a957567).
I read the following discussion (http://groups.google.com/group/
beagleboard/browse_thread/thread/4981a9811e02078c/8b96ba5c2366adc3?
lnk=gst&q=mux+mode #) and I was left with doubts.
If for example I want UART (UART2 in this case) on the expansion, this
is what I think we should do:
First, edit ~/u-boot-main/board/ti/beagle/beagle.h where all the pin
configuration, not just those associated pin expansion connector.
Then we see table 20 of BB SRM which lists the expansion connector
signals.
Here I see UART2_TX is in the mode 0 in the pin 6 of the expansion
connector, and UART2_RX is in mode 1 of the pin 8.
For me, the settings in this case should be:
MUX_VAL (CP (UART2_TX), (IDIS | PTD | DIS | M0))
MUX_VAL (CP (McBSP3_FSX) (IEN | PTD | DIS | M1))
Am I right? ...
thank you.
