To implement frame buffer, a portion of main SDRAM is used. This area is allocated at runtime by linux frame buffer driver.
Every pixel on the display has 2 possible states, ON (light pixel) or OFF (dark pixel).On the frame buffer, the memory is mapped with 8bit for pixel. A byte of value 0xFF represents a ON pixel, and all the other values (0xFE to 0x00) represent a OFF pixel.
At the following URL the Vivado design is available for download: TBD. Please note that, even if this application note is based on BELK 2.2.0, this design has been implemented with Vivado 2013.4
There are also two GPIO, controlled by the linux driver, that manage the power supply of the display (5V and 12V from BoraEVB to Lumineq Display).
