I only tested this on A1 but it should work on A2.

* Rev A2 is the same as A1 except it has: the new LSR TiWi-R2
connectivity module populated (Rev A1 of PandaBoard contained the LSR
TiWi-R1 module and the footprint of the module has changed in TiWi-R2
to improve manufacturability. See the footprint migration document for
more details.)
