OMAP-L138: SPI on OMAP-L138 LCDK Expansion header schematic

Part Number:OMAP-L138

Hi,

I am using OMAP-L138 LCDK in my project and need to use SPI to communicate with an external device.

I learned from other threads, that in order to get the SPI0 on extension header I need to  populate the R214 to R219 on the board, which are multiplexed with the Ethernet interface.

I don't plan to use the Ethernet in my project, so I was wondering whether I can leave the R172, R173, R177 to R179, and R184 or absolutely have to remove them?

What about R275 to R280 which are pulling those SPI0 lines up?

Regards,

Mohammad
