Problem with JTAG-HS3 on Zynq7000

Question

Hi,

We have bought two JTAG-HS3 debuggers.

One of them works perfectly, but the other one keeps returning:

"1  whole scan chain (device configuration stabilizing)" or "1  whole scan chain (device configuration unstable)"

when using the "targets" command.

Any idea what could be the problem?

 

Best regards

  Lars

Hi @jpeyron

 

Yes, I use the same usb cabel for both debuggers.

I tried Adept 2 and that seems to work with both my debuggers. I can scan the chain and program the FPGA.

The XSDB tool from Xilinx still doesn't work with one of the two debuggers.

 

Best regards

  Lars
