I am working with the Altera Cyclone V SoC development kit and I’m having an issue with the SignalTap II logic analyzer.
I was initially able to add the block to a simple Quatrus project and debug different signals in the project. However after some changes I am receiving the following errors when I download a .sof file through the SignalTap II window.
Info (209016): Configuring device index 2
Info (209017): Device 2 contains JTAG ID code 0x02D020DD
Error (209040): Can’t access JTAG chain
Error (209015): Can’t configure device. Expected JTAG ID code 0x02D020DD for device 2, but found JTAG ID code 0x00000000.
Error (209012): Operation failed
The device is programmed, I can tell by a change to the LED configuration on the board, but once I get these errors the SignalTap II window indicates “Invalid JTAG configuration” highlighted in yellow next to the Instance Manager and there is no way to run the analyzer.
I have removed the changes, but the issue persists. One thing that concerned me is that when the analyzer comes up there are 3 options to program the .sof file to, with option 2 being the correct choice to program the FPGA but option 1 being selected by default:
@1: SOCVHPS (0x4BA00477)
@2: 5CSEBA6(.|… (0x02D020DD)
@3: 5M2210Z/E… (0x020A40DD)
I noticed this issue after I mistakenly attempted to upload the .sof file to @1. Has anyone here seen a similar issue with SIgnalTap II and have a solution?
