SVGA support with Mistral OMAP35x

*** Read

Other Parts Discussed in Thread: OMAP3503, OMAP3530

I am trying to find out what hardware and software is required to support SVGA (800x600) resolution using RGB signaling to a display.  What video interface hardware should be used and what software drivers and/or libraries are available using the Mistral OMAP 35x?

I looked at the OMAP35x Linux PSP Release Notes for PSP 2.00.00.01 it says the framebuffer and v4l2 drivers do not work with DVI.

It also looked like there is Linux Graphics SDK to support OpenGL but it only works with SDK_V1.02 which is an older kernel.

Another source of confusion for me is the processor for this evm is supposed to be OMAP3503 yet the marking on the Mistrel board is OMAP3530 which is another type of OMAP processor.  It seems some for the Linux and graphics support one but not the other processor.  Is that true?

Can you help?

Thanks

Dick

    You may want to start with the SDK package for the Mistral EVM, the 1.0.2 version of the SDK does support DVI output with the 2.6.22 kernel, it is not available for the GIT kernel currently, I am not sure about the status of the GIT version of the DVI driver.

    This is true, you do lose some functionality with the GIT currently.

    The processor on the Mistral EVM is actually a OMAP3530, I think this has been covered in the past on the forums, but basically the original software package for the EVM only supported the 3503 feature set (no DSP or Graphics) so they called it the 3503 EVM even though the actual hardware is a 3530. In any case you can certainly use the graphics and DSP capabilities of the OMAP3 on the Mistral EVM (especially now that software is out there, though it is not using the latest kernel).
