[Gumstix-users] DuoVero-Y UART 2

[Daniel Madill]

Is UART 2 TX/RX available for use on the DuoVero-Y COM expansion connector?
If not, are there any other signals on the expansion connector that are not
available on the DuoVero-Y compared to the DuoVero?

UART 2 was available on the older DuoVero expansion connector, but I notice
in the 001-GS4430Y-DTS-changes-for-enabling-WiLink8.patch file that it
enables "pin muxing for bt which is connected over UART2". The patch adds
lines to enable UART2. We were using UART 2 on the expansion connector with
the old DuoVero. Are these pins now N/C on the expansion connector or is
there now a risk of conflict with the serial device we have connected on our
custom daughter board to the UART2 lines? Also, if our software sends
anything to UART 2 will it now be talking to Bluetooth?

BTW, the patch file to which I'm referring is under
poky/meta-gumstix/recipes-kernel/linux/linux-gumstix-3.18/.
