Function Documentation

int XLlFifo_CfgInitialize ( XLlFifo * InstancePtr,

XLlFifo_Config * Config,

u32 EffectiveAddress

)

XLlFifo_CfgInitialize initializes an XPS_ll_Fifo device along with the InstancePtr that references it.

Parameters:

InstancePtr is a pointer to the Axi Streaming FIFO instance to be worked on.

CfgPtr references the structure holding the hardware configuration for the Axi Streaming FIFO core to initialize.

EffectiveAddr is the device base address in the virtual memory address space. The caller is responsible for keeping the address mapping from EffectiveAddr to the device physical base address unchanged once this function is invoked. Unexpected errors may occur if the address mapping changes after this function is called. If address translation is not used, use Config->BaseAddress for this parameters, passing the physical address instead.

Returns:
N/A

void XLlFifo_Initialize ( XLlFifo * InstancePtr,

u32 BaseAddress

)

XLlFifo_Initialize initializes an XPS_ll_Fifo device along with the InstancePtr that references it.

Parameters:

InstancePtr references the memory instance to be associated with the FIFO device upon initialization.

BaseAddress is the processor address used to access the base address of the Fifo device.

Returns:
N/A
