TMDSEVM6657: TMDSEVM6657 - accessing SPI pins of TMS320C6657 processor inside expansion header

Part Number: TMDSEVM6657
Other Parts Discussed in Thread: TMS320C6657

Hello everyone,

I am working with TMDSEVM6657 evaluation board for TMS320C6657 processor. I would like to connect ADC and DACs to it via SPI interface. 

From technical documentation for this evaluation board I have found that SPI pins are located inside expansion header (TEST_PH1), and that coresponding SPI pins are pins 63, 65, 67 and 69. 

However, I have troubles finding the order of pins, or where exactly inside the expansion header are there located. Is the first pin the most left upper are the most right upper pin? The only indicator that I have is a small arrow on the board, which could indicate that the first pin the most right upper pin.

I would appreciate any comment or suggestion on how to setup and use this SPI port.

Thank you in advance.

Kind regards,
