TMX570LS12x and SPI2 documents

Other Parts Discussed in Thread: HALCOGEN

I am trying to access the SD card on the TMX570LS12x Hercules Development Kit (HDK) through SPI2.  The documents on the TMS570 have a section on the MibSPI function, but no section on the SPI2.  I can only find a few pin references to SPI2.  Is there really an SPI2 on the TMS570, and if so where is the documentation for the SPI2 on the TMS570?  I really need to talk to the SD card through SPI.

    Hello:

    TMS570LS12x provides 5 SPI modules.  There are 3 Multi-Buffered modules (1, 3 and 5) and 2 standard SPI modules (2 and 4).

    Control registers structure is the same on all 5 modules. In the specific case of SPI2, the base address is 0xFFF7_F600. Please also refer to Compatibility(SPI) Mode Configuration.

    Regards,

    Thank you for responding.

    I did find that the TMS570LS1227ZWT had the SPI2 available, I mostly through using the HalCoGen. Also saw that the datasheet showed pin assignments for it.   I did get the spi2  running through expermentaion.  I would very much like to know where the data specification that is specific to the SPI2 is located.  This way I would not have to read the MibSpi and  guess.
