I am trying to get UART2 on the expansion header and the different docs
appears to be conflicting. Using the Beagle Board HRM B5:
Page 83, Table 17 shows UART2 RX and TX as being available on the
expansion header's pin 8 and 10 using signals that can be configured for:
MCBSP3_FSX, GPIO_143, UART2_RX
MCBSP3_DR, GPIO_142, UART_TX
However, there does not appear to be such a combination as shown
for Pin 10 per the OMAP3530 TRM or the OMAP3530 datasheets.
The closest is ball AF5 (CBB package) which can be configured for
MCBSP3_CLKX, GPIO_142, UART2_TX.
There is another ball (AE6 on CBB) that can be configured for
MCBSP3_DR but that does not provide UART2_TX functionality.
To further complicate things, Pin 6 on the expansion header in the same table
shows it being capable of MCBSP3_CLKX. The schematics in the Beagle Board
HRM seems to be consistant with Table 17. I have not checked the gerbers for
what is actually routed since I don't have viewer handy.
Any guidance as to what is routed where?
