Hi,

The AM335X LCD controller can be used in LIDD mode for this purpose, but the Linux SDK does not include support for this mode of operation. You can refer to section 13 of the AM335X Technical Reference Manual Rev. L for description of LIDD mode, but you will need to write your own driver.

The Linux driver included in the SDK supports only raster-mode displays. See this wiki: processors.wiki.ti.com/.../Linux_Core_LCD_Controller_User_Guide
