Hi, LSP_2.00 have a very good archtecture. And I'd like to use it.
I've ported everything from dvsdk on to it. DSPLink, CMem, CodedecEnging, etc.
But when I try to run the demo, Cmem loading is ok, DSPlink loading is ok. but when run interface, system crashed.
I just printfed some infomation and found it crashed when call FBIOPUT_VSCREENINFO. No followed msgs printfed. As the Black an Italy line shows below.

can anybody tell me how pass through.
And because I have to run kdrive based win. I need to use new kernel over gcc-4.2.x for 20% higher performance than MVtool4.0.
Please help me!
And as anybody want I can share you my GCC toolchain and my DVSDK ports.
Thanks
