Still not working, and much more doubts :D
1) In board code isp_parallel_platform_data i added the bt656 = 1
setting and i see it gets applied, but reading code and omap trm i've
found that you must set ISPCCDC_REC656IF_ECCFVH flag too.
2) ispccdc.c:ccdc_config_outlineoffset(..) seems broken to me.
It is used only once in ccdc_configure:
ccdc_config_outlineoffset(ccdc, ccdc->video_out.bpl_value, 0, 0);
so the last two parameters are always set to 0, while they should be
(conditionally) set with for ex. EVENODD, 1
Moreover the implementation has this (hope it will keep formatting...):
switch (oddeven) {
case EVENEVEN:
isp_reg_set(isp, OMAP3_ISP_IOMEM_CCDC, ISPCCDC_SDOFST,
(numlines & 0x7) << ISPCCDC_SDOFST_LOFST0_SHIFT);
break;
case ODDEVEN:
isp_reg_set(isp, OMAP3_ISP_IOMEM_CCDC, ISPCCDC_SDOFST,
(numlines & 0x7) << ISPCCDC_SDOFST_LOFST1_SHIFT);
break;
case EVENODD:
isp_reg_set(isp, OMAP3_ISP_IOMEM_CCDC, ISPCCDC_SDOFST,
(numlines & 0x7) << ISPCCDC_SDOFST_LOFST2_SHIFT);
break;
case ODDODD:
isp_reg_set(isp, OMAP3_ISP_IOMEM_CCDC, ISPCCDC_SDOFST,
(numlines & 0x7) << ISPCCDC_SDOFST_LOFST3_SHIFT);
break;
default:
break;
}
But reading the omap trm (Figure 12-77) it seems to me that all the
LOFSTX should be set.
3) Last but not least, i'm using V4L2_MBUS_FMT_UYVY8_1X16 format in
tvp5150, but i'm not sure it is correct. What is the proper format for
bt656? Maybe V4L2_MBUS_FMT_UYVY8_2X8?
Thanks,
Enrico
