System Console : Jtag master

Question

Hi

I am trying to use system console to configure my design. However, system console sometimes can connect to my design and sometimes cant.

Error:

error: java.lang.StringIndexOutOfBoundsException: String index out of range: -1

while executing

"open_service master $jtag_master"

Besides, i have trying to program other design. It always work.

I have no idea where to debug.

Any idea?

Thanks

What is the value of $jtag_master when this fails?  What does [get_service_paths master] return?

Hello,

I am having the same problem. What do mean by creating a system that can talk to your design?

Or better question, What kind of mistakes would make your system console not talk to your design??

Please let me know it is very needed...

Thank YOU

Please find here (http://www.alteraforum.com/forum/showthread.php?p=151952#post151952) a walkthrough on how to use the system console in conjunction with the JTAG master.

Be aware that TCL uses whitespaces to separate multiple arguments like in the following code

set path ] 0]

If you omit the whitespace between the two arguments of lindex the path variable will be set to nonsense.

set path ]0]

This code will execute but the subsequent service request will fail because of the non-existent master.
