Hi,

The AM572x GP EVM has an HDMI output and LCD display with parallel interface. Neither of these need SPI for configuration. The LCD is configured at driver level with the correct pixel clock, resolution and color depth. For details see: processors.wiki.ti.com/.../Linux_Core_DSS_User's_Guide

Hi Biser thanks for replay.

Is there any control interface used for EVM LCD?

are you using any LCD controller driver (panel driver) for EVM LCD?

Thanks,
