using CPI 16bit interface to caputre HDMI video on OMAP4460 platform

Other Parts Discussed in Thread: SYSCONFIG

hi:

    i am using CPI of omap4460 to capture hdmi video(720p@60fps) , the hdmi receive chip is adv7611. adv7611 convert the hdmi video to 16bits YUV 4:2:2 bits. in particular, the upper 8bits corresponds to Y component, and the lower 8bits corresponds to UV component. we probe the pin of adv7612 by scope, and find that it actually output the effective hs,vs and pclk of 720p@60fps.

     as for the software setting of OMAP4 iss, the pipeline is adv7611 -> ipipeif -> ISIF ->ipipeif -> resizer, INPSRC1 (IPIPEIF_CFG[15:14) and INPSRC2(IPIPEIF_CFG[3:2]) are both set as zero, in addition, the INPUT_SEL (ISS_CTRL[3:2]) is set as 0x3(Parallel interface).

    we can receive ISS level HS_VS_IRQ interrupt, but we cann't receive isp level interrupt, neither isif&ipipeif  nor resizer interrupt occurs.

     so, what is the problem? thanks

    to assist the analysis, the register of omap4 iss is show as below:

    i has solved the problem, the keypoint is to de-assert the mstandby to ISP, we should make sure that ISP be in active state before receiving images from a sensor.

    once ISP is out of standby state, it can receive isif and ipipeif interrupt.

    but ,i encounters another problem, the image captured by resizer has black bar on the left, and i found that the image caputured by isif also has black bar. (note: the pipeline i use is adv7611(hdmi)-> cpi->ipipief->isif->ipipeif->resizer).

    i also check the data on cpi interfac

    e, and found that i doesn't output such black bar signal.

    on the hdmi tx side, the timing is 720p@60fps, and it shows a pure while picutre, but the image captured on OMAP4 isif& resizer is such:

    to assist the analysis,  i dump the regiser as below:

    Hello Guohui Li1,

    I suggest you to see following patch:

    https://gitorious.org/omap4-v4l2-camera/omap4-v4l2-camera/commit/37328b0fdb23474191fd070d293d10d0e0989071

    ISP pipelines

    CSI2A -> IPIPEIF -> MEM

    To reset all links, and link CSI2A VP output pad to IPIPEIF input node, and IPIPEIF to respective v4l2 capture device node:
    ./media-ctl -r -l '"OMAP4 ISS CSI2a":1 -> "OMAP4 ISS ISP IPIPEIF":0 [1]','"OMAP4 ISS ISP IPIPEIF":1 -> "OMAP4 ISS ISP IPIPEIF output":0 [1]'

    To set format on "ov5650 3-0036" sensor output, "OMAP4 ISS CSI2a" and "OMAP4 ISS ISP IPIPEIF" input pads:
    ./media-ctl -f '"ov5650 3-0036":0 [SGRBG10 2592x1944]','"OMAP4 ISS CSI2a":0 [SGRBG10 2592x1944]','"OMAP4 ISS ISP IPIPEIF":0 [SGRBG10 2592x1944]'

    CSI2A -> IPIPEIF -> RESIZER(A) -> MEM

    To reset all links, and link CSI2A VP output pad to IPIPEIF input node, IPIPEIF output to RESIZER input, and RESIZER-A output pad to respective v4l2 capture device node:
    ./media-ctl -r -l '"OMAP4 ISS CSI2a":1 -> "OMAP4 ISS ISP IPIPEIF":0 [1]','"OMAP4 ISS ISP IPIPEIF":2 -> "OMAP4 ISS ISP resizer":0 [1]','"OMAP4 ISS ISP resizer":1 -> "OMAP4 ISS ISP resizer a output":0 [1]'

    To set format on "ov5640 3-003c" sensor output, "OMAP4 ISS CSI2a", "OMAP4 ISS ISP IPIPEIF" and "OMAP4 ISS ISP resizer" input pads:
    ./media-ctl -f '"ov5640 3-003c":0 [UYVY 640x480]','"OMAP4 ISS CSI2a":0 [UYVY 640x480]','"OMAP4 ISS ISP IPIPEIF":0 [UYVY 640x480]','"OMAP4 ISS ISP resizer":0 [UYVY 640x480]'

    Same as above, but enabling UYVY -> NV12 conversion in ISP Resizer:
    ./media-ctl -f '"ov5640 3-003c":0 [UYVY 640x480]','"OMAP4 ISS CSI2a":0 [UYVY 640x480]','"OMAP4 ISS ISP IPIPEIF":0 [UYVY 640x480]','"OMAP4 ISS ISP resizer":0 [UYVY 640x480]','"OMAP4 ISS ISP resizer":1 [YUYV1_5X8 640x480]'

    https://gitorious.org/omap4-v4l2-camera/pages/Home

    Run resizer in one-shot mode and wait for the resizer to complete the one-shot operation by waiting for the RSZ_SRC_EN to become zero.

    Best regards,

    Yanko
