Hi all
I'm working with a board running OMAP3530 but after a lot of days of tries I'm still unable to have gstreamer working for play video. I have my custom kernel based to the original 2.6.32 version supported by TI and I'm currently use the filesystem contained into the SDKDV package version 4.0.x. I suppose to have configured the correct memory addresses for cmem but when I launch a predefined example like "runDecode_MPEG4_AAC" I can see my display become dark and I can not see any vide, I see in the serial console de following error:
