I am looking more into this and I have more questions. I am using the spiffy2 interface with the following configuration
MASTER2_P24_CLK_P27_MOSI_P25_MISO. Is there a conflict using P27 for SPI and the clock on P11?
The SPI and the other subsystems are working without problems. The only problem we are hunting down is the clock drift.

If an external 32KHz LPO is utilized, then it must be connected to P43 and P44 of the 20737S module. In this case, one cannot use the alternate functions of P12 and P11 respectively.
Thanks for your reply. That's where we have the crystal. We are using the SPI2 as well with the setup I sent above:
I noticed in the forum that GPIO P27 (physical pin 1) is connected internally to GPIO P11. Since we have problems with out setup is it possible that there is a conflict betweeen these two setups?
I see, so the alternate function of P11 is P27. That was quite confusing. Now my problems start to make sense.
