Using DVI Output on DM365Leopard
One of the capabilities on what video displaying refers to, in dm365 leopard board, is to display by using a DVI format.
First of all, it is necessary to attach the LI-DVI1 module to the Parallel RGB (PRGB) port, which is numbered J7, so it is possible to have the right hardware configuration.
DVI configuration is achieved after three basic steps, both at RidgeRung's SDK configuration menu.
1) Make sure that the dm365_generic_prgb_encoder is selected to be built. This can be checked at:
Kernel configuration -> Device Drivers -> Multimedia support -> Video capture adapters -> Generic PRGB Encoder support
2) Set the video output and standard to work on PRGB and DEF-PRGB-STD respectively
Architecture configurations -> Video Output (PRGB) Architecture configurations -> Video Default Resolution (DEF-PRGB-STD)
3) Set the standard configuration at kernel extra arguments.
Kernel configuration -> Extra kernel arguments
At this point it is important to notice that, for setting the standard, it is required to identify the module to which the information is going to, This is made by the instruction "dm365_generic_prgb_encoder.mode="
A couple examples of standards to be configured would be:
