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.
