Hi,
I use DS90UB960 to receive image from OV10635-DS90UB913(resolution 1280x720,30fps), and TDA2Px receive image from DS90UB960.
Then I found tda2px receive frame rate is half of camera real frame rate. TDA2Px receive 15fps,but camera real frame rate is 30fps.
I dump ds90ub960's regs.
I check the LOCK reg 0x4d is 0x13. It's locked.
I check the frame sync reg 0x18 is 0x00,DS90UB960 frame sync function is disabled.
I check the resolution reg 0x73-0x76, it's match of camera resolution.
DS90UB960 csi output clock is 800Mbps,it 's match of tda2px csi rate.
It seems it's all good.I have no idea why tda2px receive frame rate is half of real camera frame rate.
Could it be the cause of tda2px? May be the tda2px's MIPI CSI2 timing doesn't compatible of DS90UB960 ?
