DESCRIPTION

Data format definitions are non-standard and resulting in color components being swapped if wrong assumption is made in software.

To configure data packing/unpacking logic for each active data channel, the VPDMA (in the VIP) and/or DSS relies on the 'data type' value in the channel's data transfer descriptor. Due to mismatches in the component order directions between what the VPDMA and/or DSS specifies and what commonly used image identifiers expect, color components can be swapped in the display and in the video/image data written out to the memory for some RGB and YUV data types.

GUIDELINES

Software drivers should remap custom formats to the desired industry standard formats and/or treat data as word/byte swapped as appropriate. See also Device TRM for full explanation of data formats.
