JTAG Device ID not detected on TE0701 Carrier REV 3 & REV 5 with TE0720

[navarro.arnaud]

Hello,

Currently I am working on two diffrent boards, the TE0701-03 and TE0701-05, mounted with the TE0720.
But now, I want to use chipscope from Xilinx. I used the JTAG port and the USB emulated JTAG port, and in both cases, Impact or Vivado Hardware Manager doesn't recognise the hardware. Of course I have red your Wiki, to see what how the buttons was configurated. We correctly switched off/on the 3rd button.
In Impact we got "Identify Succeed" but we got only one unknown device. I know that we should see 2 devices (ARM + FPGA). Do you know what can be the problem?
1 year ago, I used a old revision of the TE0701 and got no issue.

Thank you.

if the jumper settings are correct than the ARM+FPGA jtag chain should be visible.

for troubleshooting you can also use ToolZ, it will show the actual ID code that is captured from JTAG, so it would be visible if some switch is set incorrectly.

First of all, thanks for answering.

In your Wikipage, (https://wiki.trenz-electronic.de/display/4X5B/TE0701+JTAG+Programming+Guide), you don't talk about jumpers of the REV 3. There is only one thing about the button 3. That's why I am bit confused about the jumpers

I found it. I just swaped all the button positions.
