Ver   Who       Date     Changes


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
GicPtris the GIC instance pointer.
DmaPtris the DMA instance pointer.
Returns
None.
Note
None.
