Other Parts Discussed in Thread: OMAP3530

hi,

 I have a demo board of OMAP3530. I want to apply it to capture data ,but not  video data.   

I want to apply ISP interface to capture RAW data to memory ( I want to save raw data  to memory ,and don't  process them ),

I config vs,hs ,et camera interface signal , I have get cam_vs,cam_hs,cam_pclk,cam_data and cam_flat signal .

But the data can't achive to the SBL ,I can see the debug reg of SBL .

    What you want to do should be possible as the CCDC in the ISP can dump data directly into memory using the RAW 8/10 bit JPEG mode as discussed in section 1.2.4.2 and 1.4.4.2 of SPRUFA2.

    I am not sure what you mean here, do you mean that the ISP is not writing out to memory? Unfortunately I have not had a chance to try out using the ISP much myself as I have no hardware to exercise it with, but there is some example driver source within OMAP35x_SDK_1.0.2\src\linux\kernel_org\2.6_kernel\drivers\media\video\omap that may be of help in comparing to your setup.

    Hi Bernie,

    It's been a while since the last post in this thread, but I'm trying to get hold of SPRUFA2 and the link above is dead. Any idea where I could get hold of the document?

    Thanks,
