1.00    hbm    08/19/2010 First Release
1.01a nm     03/05/2012 Initializing DmaCmd structure compatible to armcc.
                        Modified base address to secure register base
                        address.
1.02a sg     05/16/2012 Some code cleanup and reorganisation of the
                  functions within the example.
1.06a kpc    04/24/2012 Modified the APIs to make this file compatible with
                        peripheral test suite.
2.1   kpc    08/23/2014 Fixed IAR compiler reported error.
2.3   ms     01/23/17  Modified xil_printf statement in main function to
                       ensure that "Successfully ran" and "Failed" strings are
                       available in all examples. This is a fix for CR-965028.

int main

(

void

)

This is the main function for the DmaPs interrupt example.

Parameters

None.

Returns

XST_SUCCESS to indicate success, otherwise XST_FAILURE.

Note

None.

References XDmaPs_Example_W_Intr().

int SetupInterruptSystem	(	XScuGic *	GicPtr,
		XDmaPs *	DmaPtr
	)

This function connects the interrupt handler of the interrupt controller to the processor.

This function is seperate to allow it to be customized for each application. Each processor or RTOS may require unique processing to connect the interrupt handler.

Parameters

GicPtr	is the GIC instance pointer.
DmaPtr	is the DMA instance pointer.

Returns

None.

Note

None.

int XDmaPs_Example_W_Intr	(	XScuGic *	GicPtr,
		u16	DeviceId
	)

Interrupt Example to test the DMA.

Parameters

DeviceId

is the Device ID of the DMA controller.

Returns

XST_SUCCESS to indicate success, otherwise XST_FAILURE.

Note

None.
