hi ,
I have a problem about dm365 bt.656 digital output configure. In my system , I want to output a SD PAL video through VPBE bt.656 interface. But the output video display a reversed odd field and even field, that looks like field ID or the field data is reversed. I cannot find the how to fix it .
The VENC parameter is configured as following:
dispc_reg_out(VENC_VMOD, 0x1043);
dispc_reg_out(VENC_CLKCTL, 0x11);
dispc_reg_out(VENC_VIDCTL, 0x6000);
dispc_reg_out(VENC_YCCCTL, 0x1);
dispc_reg_out(VENC_OSDCLK0, 1);
dispc_reg_out(VENC_OSDCLK1, 2);
dispc_reg_out(VENC_VDPRO, 0x20);
__raw_writel(0x081141CF, IO_ADDRESS(DM3XX_VDAC_CONFIG));
/* VPBE PINMUX */
unsigned int temp = 0;
void __iomem *pinmux1 = (void __iomem *) IO_ADDRESS(0x01C40004);
temp = __raw_readl(pinmux1); //select VCLKL and HVSYNC
temp &= ~(0x01 << 22); //VCLK Enable
__raw_writel(temp, pinmux1);
dispc_reg_out(VENC_SYNCCTL, 0);
osd_write_left_margin(mode_info->left_margin);
osd_write_upper_margin(mode_info->upper_margin + 2);
dispc_reg_merge(VENC_VMOD, VENC_VMOD_VENC, VENC_VMOD_VENC);
dispc_reg_out(VENC_DACTST, 0x0);
dispc_reg_out(VENC_CMPNT, 0x0);
