I have an OrangePi and I'm trying to get a gc2035 camera working. I'm using a 3.4.103 kernel and I'm writing a sun4i_csi0 driver. It works in single frame mode but in video mode I get the first four frames then it repeats a sequence of the first three frames followed by the latest frame. The maximum frame rate I can achieve (with streamer or guvcview) is about 2.5 frames per second. So I'm dropping most of the frames but what I can't understand is why I'm getting a repeat of the first three frames.
The maximum frame rate is limited because the OrangePi is headless and I'm using X11 via ssh to access it. But if I get streamer to write a local file rather than send the stream I still get the repeat of the first three frames. I do see error messages from v4l2 reporting "waiting for a free buffer" and also "rate: queueing frame twice" messages. I have a GC2035 datasheet but the details are very limited and many registers are marked as reserved. Has anybody heard of my frame repeat problem or can anybody suggest where I can find the buffer list code ?
