2.2 BSP Rel. 1.0 for PPMC-275 Programmer's Guide

API Call Reference List of APIs
void frcDmaTestStart0(DMA_ENGINE dmaEngine, unsigned int xferSize, char srcIf, char tgtIf,
char dmaData, unsigned int dmaDtl)
This routine spawns a task on the CPU that copies data from
DRAM/SRAM/PCI to DRAM/SRAM or PCI. After initiating the
transfer, it waits for the completion signal from interrupt handler.
It then computes the checksum at the destination to verify that the
transfer is indeed complete without any errors.
INPUT
DmaEngine One of the 4 DMA engines
XferSize Transfer size
srcIf Source interface which indicates DRAM/SRAM or PCI
tgtIf Target interface which indicates DRAM/SRAM or PCI
dmaData Data that has to be transferred.
DmaDtl The DMA command that has to be combined with the
block_transfer_mode command.
OUTPUT Output Transfers the dmadata between the two interfaces through
the DMA engine
RETURNS Not Applicable.
