Function Documentation

bool fwCcpc_JTAGChainScan	(	string	pCCPC,
		int	pChain,
		dyn_int &	pDeviceAddressList
	)

This function performs a JTAG scan operation on the specified CCPC.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	chain number from '1' to '3'.
[out]	pDeviceAddressList	list containing the addresses of the devices.

Returns:

true no error found.

false error found.

Example:

  (...)
  dyn_int myList;
  int     i;

  if (fwCcpc_JTAGChainScan("pclbcecs03", 1, myList) == 0)   // scans JTAG chain no.1 for connected hardware
     for(i = 1; i <= dynlen(myList); i++)
        DebugTN("Device Nr. " + (string) i + " has address " + fwCcpc_convertDecToHex(myList[i]));
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_JTAGDRScan	(	string	pCCPC,
		int	pChain,
		int	pSize,
		dyn_char	pDataIn,
		dyn_char &	pDataOut
	)

Perform a DR SCAN operation on the specified JTAG chain.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	chain number from '1' to '3'.
[in]	pSize	size (in bits) of the data to be shifted in. Note: the first bit to be shifted in will be the rightmost bit of the data.
[in]	pDataIn	data to be shifted in.
[out]	pDataOut	data that has been shifted out.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  dyn_char myData;

  if (fwCcpc_JTAGDRScan("pclbcecs03", 1, 24, fwCcpc_convertHexToByte("feedbabe"), myData) == 0)   // perform a IR SCAN operation
     DebugTN(fwCcpc_convertHexToByte(myData));
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_JTAGIdle	(	string	pCCPC,
		int	pChain
	)

IDLE operation: A state movement to ENDST_TLRST is performed.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	number of chain from '1' to '3'.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_JTAGIdle("pclbcecs03",1) == 0)   
     (...)
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_JTAGIRScan	(	string	pCCPC,
		int	pChain,
		int	pSize,
		dyn_char	pDataIn,
		dyn_char &	pDataOut
	)

Perform a IR SCAN operation on the specified JTAG chain.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	chain number from '1' to '3'.
[in]	pSize	size (in bits) of the data to be shifted in. Note: the first bit to be shifted in will be the rightmost bit of the data.
[in]	pDataIn	data to be shifted in.
[out]	pDataOut	data that has been shifted out.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  dyn_char myData;

  if (fwCcpc_JTAGIRScan("pclbcecs03", 1, 24, fwCcpc_convertHexToByte("feedbabe"), myData) == 0)   // perform a IR SCAN operation
     DebugTN(fwCcpc_convertHexToByte(myData));
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_JTAGReset	(	string	pCCPC,
		int	pChain
	)

RESET operation: A state movement to ENDST_TLRST is performed.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	number of chain from '1' to '3'.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_JTAGReset("pclbcecs03",1) == 0)   // perform a RESET operation
     (...)
  else
     DebugTN("Error found!");
  (...)

int fwCcpc_JTAGResetTAP	(	string	pCCPC,
		int	pChain
	)

Perform a TAP reset operation.

Parameters:

[in]	pCCPC	name of the CCPC.
[in]	pChain	chain number from '1' to '3'.

Returns:

= 0 no error found.

> 0 error found (related with CCPC Server).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwCcpc_JTAGResetTAP("pclbcecs03", 1) == 0)   
     (...)
  else
     DebugTN("Error found!");
  (...)
