Detailed Description

LCB Local Cmd/Response exercise tests.

Author:

Ed Bacho -- ebacho@slac.stanford.edu These tests access only the LCB-resident registers that must be accessed through a DMA (i.e. they are in the LATp FPGA, or LATp side of the board.

Function Documentation

int LCBT_cmdLocalTest	(	int	num,
		TDATA_DTEST	testType,
		unsigned int	testParm
	)

read-only test on LCB local registers that require Cmd list DMA

Parameters:

	num	Number of accesses to do in the test
	testType	Specifies the data sequence for test
	testParm	Parm to use with testType

Returns:

total errs

int LCBT_cmdLocalTest2	(	int	num,
		TDATA_DTEST	testType,
		unsigned int	testParm
	)

2 task read test on LCB local registers that require Cmd list DMA

Parameters:

	num	Number of accesses to do in the test
	testType	Specifies the data sequence for test
	testParm	Parm to use with testType

Returns:

total errs This is similar to LCBT_cmdLocalTest except that two tasks are spawned and do the test concurrently.

int LCBT_cmdLocalTest3	(	int	num,
		TDATA_DTEST	testType,
		unsigned int	testParm
	)

3 task read test on LCB local registers that require Cmd list DMA

Parameters:

	num	Number of accesses to do in the test
	testType	Specifies the data sequence for test
	testParm	Parm to use with testType

Returns:

total errs This is similar to LCBT_cmdLocalTest except that three tasks are spawned and do the test concurrently.

(

unsigned int

stall

Returns:

status To be used with great discretion, i.e. in case of emergency break glass.
