About a err message in NiosII

When I applied ByteBlasterII to download

my program into the dev board from Altera,

something internal error info cames out,

which seemed about the viability of my

ByteBlasterII programmer.

You see,the error message went like this

and ended with some other message:

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

nios2-terminal:

Warning: The JTAG cable you are using is not supported for Nios II systems.

You may experience intermittent JTAG communication failures with this cable.

Please use a USB Blaster revision B cable or another supported cable.

Please refer to the file

errata.txt included in the Nios II development kit documents

directory for more information.

connected to hardware target using JTAG UART on cable

"ByteBlasterII [LPT1]", device 1, instance 0

starting in terminal mode only (Control-C exits)

nios2-terminal: exiting due to I/O error communicating with target

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

Followed the error info,I found the file errata.txt

and skimmed it(about the part of configuration) .

However,I could not find anything that was helpful to me.

--Does the error info mean that all the ByteblasterII

cables can not be used for downloading programs

into NiosII?

--And as for me,does that mean that I have to find

(or just buy)a "USB Blaster revision B cable or

another supported cable"to complete my work?

--Could you please give some hints to resolve the

problem and make it work without buying

a new programming cable(such as a USB Blaster

revision B cable )?

Regards,

Don
