TSE MAC and SGDMA

Thanks,

I think i am free the allocated buffer as shown below,

do

{

printf("Starting up the SGDMA Receive engines\n");

if(alt_avalon_sgdma_do_async_transfer(receive_DMA, &receive_descriptors[0]) != 0)

{

printf("Writing the head of the receive descriptor list to the DMA failed\n");

return 1;

}

/**************************************************************

* Blocking until the SGDMA interrupts fire *

************************************************************/

while(rx_done == 0) {}

printf("The receive SGDMA has completed\n");

/**************************************************************

* Verify the returned data and free up the data buffers *

************************************************************/

success_code = validate_results_rx(receive_descriptors,

NUMBER_OF_BUFFERS

);

printf("validate_result_rx_success_code %d\n",success_code); //0 for valid frame and 1 for other frame which i don't want.

if(success_code == 1)

{

/* Make sure SGDMA controller is not busy from a former command */ //In short we chech ready busy flag over here.

while ((IORD_ALTERA_AVALON_SGDMA_STATUS(SGDMA_ST_TO_MM_BASE) & ALTERA_AVALON_SGDMA_STATUS_BUSY_MSK))

{ }

printf("Its time to check another frame :) \n");

free(receive_descriptors_copy);//here i free my aloocated buffer

}

else

{

printf("You catch the correct frame\n");

}

} while(success_code==1);
