STM32F4 Initialization

Hi, I just upgraded my previous project from Chibi 2.5 to 2.6.1.
I upgraded the board files also, with the new definition for using SPI2 peripherals on PB12-13-14-15; but when I run the demo, SPI2 does not work.
If I do pin configuration in demo software (main.c) SPI2 works fine, so question is: why board file configuration is not working?
thanks.

Which board? all the board files I see have those pins undefined or assigned to OTG HS.

Oh, well... it's a custom made board
It's a design of mine
which runs ChibiOS successfull since release 2.4.2

PS. this is part of my board.h, which defines SPI2 pins:

This is strange because board files do not depend on anything external. Not sure abut what the problem could be, you should verify if the GPIO registers are initialized correctly.

I forget to tell you I run another application (bootloader) just before the main app.
But the board configuration files are always the same.

I do initialize SPI device in a separate process: could this be the problem of incorrect initialization of spi pins?

The SPI driver does not initialize pins so it should not matter.
