PA6 extension header

hello,

i'm using the extension header (2x10) to control some external peripherals. no problem so far.

i'm using the PA6 pin as an input - but when i call the MEMS init function the pin changes it's level to vcc
and it's not possible to pull this pin low.
i found out that the call  SPI_Cmd( SPI2, ENABLE ); is the point where the IO configuration seems to be changed.

i'm using the ST libs without circle OS.
the primer version is 1.2.

i didn't found out why this happens - any ideas?

thanks,
matthias
