Debug Connector 60-Pin (J7)

This connector enables interfacing of LVDS signals to the DCA1000 EVM for data capturing purposes as well as SPI, I2C, JTAG, GPADC, and other control signals from the AM273x EVM for debug purposes.

The SPI interface must be muxed to the Debug Connector. For more details, refer to Section 2.1.3.
