VPSS Initialization Issue

[kannan]

Hi,

In one of my project , I am using VPSS(Full Fledged) for scaling video. I used the following functions to init the IP core in SDK.

XVprocSs_SetFrameBufBaseaddr(pVprocss,DDR);

VprocSsConfigPtr = XVprocSs_LookupConfig(XVPROCSS_ID);
if(VprocSsConfigPtr == NULL)
{
xil_printf("ERR:: VprocSs IP not found\r\n");
}
Status = XVprocSs_CfgInitialize(pVprocss, VprocSsConfigPtr,VprocSsConfigPtr->BaseAddress);
if(Status != XST_SUCCESS)
{
xil_printf("VSSP init failed\n\r");
}
else
{
xil_printf("VSSP init passed\n\r");
}

To check function initialization , i am using Debugger in SDK.  The first two function is executed without any issue. when control comes into XVprocSs_CfgInitialize(pVprocss, VprocSsConfigPtr,VprocSsConfigPtr->BaseAddress), it stuck at 

if(InstancePtr->RouterPtr) {
if(XVprocSs_SubcoreInitRouter(InstancePtr) != XST_SUCCESS) {
return(XST_FAILURE);
}
}

I have attached the screen shot of debugging window. Please help me to debug it.

Thanks

The control stuck at this function

void XAxisScr_MiPortDisableAll(XAxis_Switch *InstancePtr)
{
u32 MiPortAddr;
u8 Index;

/* Verify argument. */
Xil_AssertVoid(InstancePtr != NULL);

for (Index = 0; Index < InstancePtr->Config.MaxNumMI; Index++) {

/* Calculate MI port address of which to be enabled */
MiPortAddr = XAXIS_SCR_MI_MUX_START_OFFSET + 4 * Index;

XAxisScr_WriteReg(InstancePtr->Config.BaseAddress, MiPortAddr,
XAXIS_SCR_MI_X_DISABLE_MASK);
}
}

Hi,

Is there any solutions for that?

Hi @kannan,

Could you start with the example design for the VPSS?

The application example design is really helpful as the VPSS requires steps to be done in a specific order.

Hi florentw,

Thank for your response.

I have no issue with example design.

I am getting timing violation in my design which is related to Video Processing Subsystem and AXI Interconnect.

Could it be possible of Initialization issue?

HI @kannan,

Yes you have a big timing violation so it might be the root cause. You should try to fix it first.
