Hi team,
VOUT0 is connected externally to NVP6021, NVP6021 pin definition is as follows:
TDA4VM <==> NVP6021 H/W connection is as follows：
VOUT0_DATA2~9 is connected to NVP6021 Y0~7
VOUT0_DATA12~19 is connected to NVP6021 C0~7
The customer select 1920*1080p 25fps, NVP6021 timing:
SDK: appti-processor-sdk-rtos-j721e-evm-08_05_00_11
And the customer made the following changes in SDK:
app_init.c: appDssDefaultInit()
prm.timings.hFrontPorch = 0U;
prm.timings.hBackPorch = 0U;
prm.timings.hSyncLen = 720U;
prm.timings.vFrontPorch = 0U;
prm.timings.vBackPorch = 0U;
prm.timings.vSyncLen = 45U;
prm.timings.pixelClock = 74250000ULL;
app_init.c: appDctrlDefaultInit()
vpParams.dvoFormat = APP_DCTRL_DV_BT1120_EMBSYNC;
app_dss_defaults.c appDssDefaultInit()
else if(prm->display_type==APP_DSS_DEFAULT_DISPLAY_TYPE_DPI_HDMI)
{
appLogPrintf("DSS: Display type is HDMI !!!\n");
obj->nodeOverlayId = APP_DCTRL_NODE_OVERLAY2;
obj->nodeVpId = APP_DCTRL_NODE_VP2;
obj->nodeDpiId = APP_DCTRL_NODE_DPI_DPI0;
obj->overlayId = APP_DSS_OVERLAY_ID_2;
obj->vpId = APP_DSS_VP_ID_2;
//yaogang modify
//obj->videoIfWidth = APP_DCTRL_VIFW_24BIT;
obj->videoIfWidth = APP_DCTRL_VIFW_16BIT;
}
Is the above config ok OR is it required to make any modifications? Could you help check it? Thanks.
Best Regards,
Cherry
