Hi, First of all you have to specify which version of camera interface driver you are using. Because, there are two versions of omap3 camera interface. First one is from TI, and second one is from Sakari Ailus. (second one is the latest) Besides the version issue, there are some point that you can check. 1. make sure that you are using parallel mode (if you are not using MIPI) 2. check your dataline shift 3. check your H/W connection and check parallel bridge setting And in case of you are using Sakari's new driver, you can check for the wait_hs_vs in isp_interface_config.

At the camera side, the 8 bits BT656 signal are connected to cam_d[0-7], which looks OK. The cam_fld, cam_hs and cam_vs are also connected, At the omap3 side, I use saMmapLoopback.c, it runs, however, it receives only HS_VS_IRQ, but no any image data. I checked FLDSTAT(CCDC_SYN_MODE), it's never changed. > Right now, I don't know what to check, if you can give some suggestions, your help will be greatly appreciated.
