Hi,
I'm looking for support, documentation or training to be able to use correctly VPS driver, focus on DSS, DISPC and HDMI.
I have used DisplayDSS project present in pdk (setup env, creatproject and also rebuild lib) thanks to scripts available.
But it's appears that this project is very huge and complex not useful to use.
I'm trying to setup a project just with parts that match with my use case (test case 11 of displayDSS project) .
Now I have an issue when I send IOCTL command to set DSS parameters (on validation VpsCore_dssValidateDssParams) dues to the size and format. I don't understand why.
Do someone help me on this topics ?
Here my strait forward code:
Vps_InitParams vpsInitPrms;
Fvid2_Handle dctrlHandle;
Bsp_PlatformSetPllFreq vPllCfg;
Bsp_PlatformVencSrc vencClkCfg;
int32_t retVal = FVID2_SOK;
// EDMA3_DRV_Handle hEdma;
// EDMA3_DRV_Result edmaResult = 0;
appPrint("\n hdmi dss task started...\r\n");
appPrint(" configuration match with DisplayDSS project -> test case : 11\r\n");
Fvid2_init(NULL);
VpsInitParams_init(&vpsInitPrms);
vpsInitPrms.irqParams.dssIrqNum = CSL_INTC_EVENTID_DSS_DISPC;
Vps_init(&vpsInitPrms);
//hEdma = edma3init(0, &edmaResult);
/* Create DCTRL handle, used for common driver configuration */
dctrlHandle = Fvid2_create(FVID2_VPS_DCTRL_DRV, VPS_DCTRL_INST_0, NULL, NULL, NULL);
vPllCfg.videoPll = BSP_PLATFORM_PLL_HDMI;
vPllCfg.pixelClk = 29232U * 4U;;
vPllCfg.chooseMaxorMinMN = (uint32_t) BSP_PLATFORM_VIDEO_PLL_CALC_MAX_MN;
retVal = Bsp_platformSetPllFreq(&vPllCfg);
