CHANGE_EDREG JTAG instruction via a JAM file

Hi,

I'm trying to generate .jam file to modify CRC checksum with the following file :

crc_error.jam

---------------------

NOTE "DEVICE" "EP2S30";

NOTE MAX_FREQ "10000000";

ACTION CONFIG_IO = EXECUTE;

PROCEDURE EXECUTE;

BOOLEAN X = 0;

DRSTOP IDLE;

IRSTOP IDLE;

STATE IDLE;

IRSCAN 10, $015;

DRSCAN 32, $FFFFFFFF;

STATE IDLE;

EXIT 0;

ENDPROC;

' END OF FILE

CRC 19a6;

---------------------

Quartus II Programmer send back the following message style for the previous crc_error.jam file and from the generated Quartus II MyFGPA.jam file (generated from .sof) :

"Error : programming error : multiple files specified for Programmer"

The JAM player doesn't support DO_PROGRAM or PROGRAM action for the crc_error.jam file

My configuration is built as follow :

- Stratix II EP2S30 with EPCS64

- .JIC file built from .SOF file

How can I generate properly .JAM file for EP2S30 and which software can I use to change CRC value on Stratix EP2s30 ?

Thanks a lot
