I have custom made camera module with AR0330 sensor connected to TK1.
I’ve successfully managed to confiure sensor to required configuration (1080p@30FPS) and get an image out of it.
I can confirm that the signals looks right on oscilloscope, but I am not 100% sure that the sensor really produces the frames at 30Hz (but it should since I’ve followed another ones initialization code).
I am having those syncpt failures (zero registers removed):
[ 391.672970] vi vi.0: CSI_A syncpt timeout, syncpt = 180, err = -11 [ 391.683950] TEGRA_CSI_CSI_CIL_A_STATUS 0x00000001 [ 391.696746] TEGRA_CSI_CSI_CILA_STATUS 0x00010010 [ 391.705313] TEGRA_CSI_CSI_PIXEL_PARSER_A_STATUS 0x00000000 [ 391.717745] TEGRA_VI_CSI_0_ERROR_STATUS 0x00000001 [ 391.925095] vi vi.0: CSI_A syncpt timeout, syncpt = 182, err = -11 [ 391.933780] TEGRA_CSI_CSI_CIL_A_STATUS 0x00000001 [ 391.945749] TEGRA_CSI_CSI_CILA_STATUS 0x00010010 [ 391.955139] TEGRA_CSI_CSI_PIXEL_PARSER_A_STATUS 0x00000000 [ 391.966749] TEGRA_VI_CSI_0_ERROR_STATUS 0x00000001 [ 392.179054] vi vi.0: CSI_A syncpt timeout, syncpt = 184, err = -11 [ 392.189032] TEGRA_CSI_CSI_CIL_A_STATUS 0x00000001 [ 392.195223] TEGRA_CSI_CSI_CILA_STATUS 0x00010010 [ 392.200625] TEGRA_CSI_CSI_PIXEL_PARSER_A_STATUS 0x00000000 [ 392.207011] TEGRA_VI_CSI_0_ERROR_STATUS 0x00000001
There are ~4 failures per second and when I start recording using gstreamer to raw file, there are exactly one frame filled with real image followed by three empty frames each second. This makes me think that even the “valid” frame is not accepted and ends with timeout (it is possible since i can see tears in some frames, like the data are continuously overwriting).
If I am reading those register correctly, there are single bit errors each frame (it is really each frame, since I modified vi2.c to clear errors after read out) and lines are too short (which is also strange because in the captured frame is no missing pixel column).
Could this be problem with CSI-2 bus timing configuration or is there something else to configure?
Thank you for the assistance!
