Detailed Description

Test for LCBB boot driver.

Author:

Ed Bacho - ebacho@slac.stanford.edu

    These routines are for testing the LCBB driver by setting it up as an echo server.
   
    The subroutines are structured to be used thru the WindSh rather than
    be called by other progs. They assume a single LCB board.

Enumeration Type Documentation

enum _LCBTB_OPTION

Enumeration values: LCBTB_OPTION_BUSYPRINT  print count every 1000 accesses LCBTB_OPTION_VERBOSE  lots of printouts LCBTB_OPTION_COMPARE_FOR_ECHO  use compare server for echo server

Function Documentation

int LCBTB_echo (  int  numMsg  )

single task message echo server using boot driver Parameters: numMsg  number of messages to process, 0=forever Returns: status THis function is used to test the boot driver. It will just echo back any messages received. Since it is the boot driver, it does not use interrupts. It is a single task which polls for a message. Note that the sending CPU does not need to be runnning the boot driver (or even jj's driver). The intent was that the other CPU could be running LCBT_eventTest().

Here is the call graph for this function:

int LCBTB_init (  int  latpAddr, int  useRedundantPath )

inits LCBB boot driver Parameters: latpAddr  LATp addr to assign to this board, 0=uses boardId as set useRedundantPath  0=normal path, 1=redundant path Returns: status

void LCBTB_latReset (  unsigned int  stall  )

sends LAT reset (requires a DMA) Parameters: stall  stall after reset in 50 nSec tics Returns: status To be used with great discretion, i.e. in case of emergency break glass.

unsigned int LCBTB_readFifoFault (   )

read Fifo fault register (requires a DMA) Returns: value in register

unsigned int LCBTB_readLatpCsr (   )

read LATp CSR register (requires a DMA) Returns: value in register

unsigned int LCBTB_readStats (   )

read stats register (requires a DMA) Returns: value in register

void LCBTB_regs (   )

Readall regs. Returns: none

Here is the call graph for this function:

void LCBTB_setEpu (  int  idx  )

Set boardID in Csr to EPU addr. Parameters: idx  which EPU,0=EPU0,1=EPU1,2=EPU3 Returns: none

void LCBTB_setOption (  unsigned int  mask  )

set test option mask, see LCBT.h for values Parameters: mask  mask of tests options Returns: none

void LCBTB_setSiu (  int  idx  )

Set boardID in Csr to SIU addr. Parameters: idx  which SIU,0=SIU0,1=SIU1 Returns: none

unsigned int LCBTB_writeFifoFault (  unsigned int  data, unsigned int  mask )

write Fifo Fault register (requires a DMA) Parameters: data  value to write to register mask  mask of bits to write, if 0 will default to full register Returns: value in register

unsigned int LCBTB_writeLatpCsr (  unsigned int  data, unsigned int  mask )

write LATp CSR register (requires a DMA) Parameters: data  value to write to register mask  mask of bits to write, if 0 will default to full register Returns: value in register

unsigned int LCBTB_writeStats (  unsigned int  data, unsigned int  mask )

write Fifo Fault register (requires a DMA) Parameters: data  value to write to register mask  mask of bits to write, if 0 will default to full register Returns: value in register
