Hi All, I'm working on video image capture(omap3 isp) interface(PSP 1.0.2), and have met many difficulties. 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. Thanks in advance.
I haven't been using the parallel interface nor I know anyone else who would have. Sergio, any idea?
Anyway, this sounds like a problem in the parallel receiver side. You could try also configuring the VD1 IRQ to happen much earlier, say on 10th line. See ISPCCDC_VDINT handling in ispccdc.c.
I'm going to update the patchset as soon as I get linux-omap booting again. -- Sakari Ailus sakari.ailus@xxxxxxxxxxxxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
