Function Documentation

int driverInit

(

)

Initialize VTC and TPG driver instances.

This function looks up the configuration for VTC and both TPG instances, then initializes them with their respective base addresses.

Returns

XST_SUCCESS if initialization succeeds XST_DEVICE_NOT_FOUND if device lookup fails XST_FAILURE if initialization fails

Note

This function must be called before using any VTC or TPG functionality

int main

(

)

Main function to test TPG video pipeline.

This function tests the TPG video pipeline by sequentially running tests for different video modes (1080p60, 4K30, and optionally 4K60). Each test configures the clock, video IPs, and verifies video lock status.

Returns

XST_SUCCESS if all tests pass XST_FAILURE if any test fails

Note

4K60 test only runs if TPG is configured for 2/4/8 pixels per clock

References XV_tpg::Config, driverInit(), XV_tpg_Config::PixPerClk, resetIp(), videoClockConfig(), and videoIpConfig().

void resetIp

(

void

)

Reset video IP cores.

This function asserts and then releases reset for all HLS-based video IP cores in the system using GPIO control.

Returns

None

Note

Reset is held for 300ms before release, followed by 300ms settling time

int videoClockConfig

(

XVidC_VideoMode

videoMode

)

Configure video clock generator for specified video mode.

This function programs the video clock wizard with appropriate PLL settings to generate the required pixel clock for the specified video mode and pixels-per-clock configuration.

Parameters

videoMode

Video mode that determines clock frequency requirements

Returns

XST_SUCCESS if clock configuration and lock succeeds XST_FAILURE if video mode is unsupported or clock fails to lock

Note

Supports 1080p60, 4K30, and 4K60 modes with 1/2/4/8 pixels per clock

void videoIpConfig

(

XVidC_VideoMode

videoMode

)

Configure video IP cores for specified video mode.

This function configures both TPG instances and VTC with timing parameters for the specified video mode. TPG0 generates color bars, TPG1 is configured for passthrough mode, and VTC generates timing signals.

Parameters

videoMode

Video mode to configure (e.g., 1080p60, 4K30, 4K60)

Returns

None

Note

Video clock must be configured before calling this function
