Hi @zaid786,

 

Can you try reducing JTAG frequency and check again?

Thanks,
Arpan

I am getting this message from today!

 

Windows 7 Pro + Vivado 2017.2

The 4 ILA cores inside are being detected properly.

 

Any hints why this is happening?

Check if the JTAG frequency is higher than dbg_hub clock frequency. If it is, lowers it down.

Besides, do not connect multiple cable to PC at the same time.

I tried reducing the JTAG clock frequency as indicated, but did not help, still get the following error

 

refresh_hw_device [lindex [get_hw_devices] 0]
INFO: [Labtools 27-2302] Device xc7vx690t (JTAG device index = 0) is programmed with a design that has 1 ILA core(s).
invalid vector<T> subscript

 

There was no additional information in the error message to debug as well.

Hi , my question is how fast is your ILA clock? What is the width of your probe?

Perhaps you could try this: 

 


Workaround: if an eFuse programing error occurs, the user needs to manually execute refresh_hw_device to update all the device settings.

 

It was a suggestion from a similar thread. I havent tried it out myself.

 

Best regards
