DRV8312-C2-KIT: What's the SPI pinout

Part Number: DRV8312-C2-KIT

I want to connect my DRV8312-C2-Kit to a Raspberry Pi via SPI, but I can't find information about the pinout of the board connector J8. What's the pinout of this connector? I can't even tell, which pin is pin 1. There is a dot on the left and an arrow on the right of the connector, what do they mean?

On a related note, what's the purpose and pinout of the board connector J5? It's not even mentioned once in the Hardware Reference Guide pdf...

    For J8, the pin marked with the arrow (pin 5) is GND. Pins 1-4 are, in order, SPI-SIMO/SPI-CLK/SPI-SOMI/SPI-STE. For future reference, take a look at the schematic and board layout PDF in the hardeware dev package (HWDevPkg) in ControlSUITE.

    J5 is a jumper used to monitor "important" system signals, such as QEP lines, PWM lines, current and voltage feedback lines, etc. You can find the pin-out on page 2 of the schematic I mentioned above.
