Part Number: TMDSLCDK6748
I am using a TMDSLCDK6748 evaluation board. I want to configure the SPI communication in the board using SPI0 communication. But only the SPI0_SIMO, SPI0_SOMI and SPI0_SCLK pins are available in the J15 there is no chip select pin out from any of the output jumpers. They seem to be connected to the LAN IC, U23, LAN8710A-EZK. SPI1 communication is available and seems to be connected to the camera header.
Please suggest a way to use the SPI communication in the board.

.Thank you .
SPI0_ENAn/EPWM0_B/MII_RXDV; SPI0_SCSn_5/UART0_RXD/MII_RXD3 and SPI0_SCSn_4/UART0_TXD/MII_RXD2 are available on the expansion headers.
You need to correctly pinmux C17, C19 and D18 balls of the TMS320C6748 device:
Then see page 11 of the schematic:
You need to populate R214 through R219 to physically connect the device ball to expansion header. After that you can use J15.P21, J15.P23, J15.P25, J15.P27, J15.P29, J15.P31 for SPI communication.

Please make sure you read the forum guidelines first.

In reply to Harikrishnan R S:
The camera interface is J16. See the schematic. What do you mean by pin headers for interfacing with J16?? Best Regards, Yordan
I have populated the resistors, but the output signals are getting distorted in those pins.
