I was using my ICE-100B with a propietary board that integrated a BF506F when it started to fail. First I couldn't connect to the target DSP and appeared the next message in the screen:
"VisualDSP has detected 0 device(s) in the JTAG
Chain yet there are 1 device(s) listed in this platform.
Please verify that all settings are correct in the ICE configuration utility."
I have used this JTAG with this board before since three months ago and sometimes I could see this message, but I only needed to restart the VisualDSP and it works well. But now this message never dissapear.
Then, I selected the ICE Test option and I could see that in the device ID appears 0. I have used an ADSP-BF50F EZ_KIT LITE till now, and the device ID is different. Then, I tried to make a test, and the test fail when it arrived at the point: "Determining scan path length".
After that, I changed the USB port, but the result was worse. Now, Windows doesn`t detect the JTAG and the MON Led is off .
I don't know what is the problem. How can I repair my JTAG?
Thank you in advance,
