int XV_frmbufwr_Initialize	(	XV_frmbufwr *	InstancePtr,
		u16	DeviceId
	)

Initialize the frame buffer write core instance.

This function initializes an XV_frmbufwr instance using the configuration corresponding to the specified DeviceId. It looks up the configuration, checks for validity, and then calls the core's configuration initialization function. If the configuration is not found, the instance is marked as not ready and an error code is returned.

Parameters

InstancePtr	Pointer to the XV_frmbufwr instance to be initialized.
DeviceId	Unique device ID of the frame buffer write core.

Returns

• XST_SUCCESS if initialization was successful.
• XST_DEVICE_NOT_FOUND if the configuration for the given DeviceId was not found.
