Signaltap - Crashing when attaching .sof file - Signaltap - Crashing when attaching .sof file Hi all, I generated a .sof file on a server running CentOS 8 and Quartus Pro 20.4. I am attempting to run a signaltap on the .sof after dragging it to a server running RHEL 7.9 and Quartus Pro 20.4. My process: 1. run /intel/intelFPGA_pro/20.4/quartus/bin/.quartus_stpw (Signaltap Pro) 2. Configure stp (see screenshot) 3. Attempt to attach .sof -> crash *** Fatal Error: Segment Violation: faulting address=0xfffffffffffffff8, PC=0x7f735f7b99c5 : 0x7f735f7b99c5: sld_sdr!SDR_DATA_SESSION::embed_sof_file(char const*, char const*) + 0x8b9 Thanks, George Replies: Re: Signaltap - Crashing when attaching .sof file Glad to hear that your issue is resolved. Replies: Re: Signaltap - Crashing when attaching .sof file I have solved my issue by programming from the programmer independently: run /intel/intelFPGA_pro/20.4/quartus/bin/.quartus_pgmw Replies: Re: Signaltap - Crashing when attaching .sof file Step 2 I am simply scanning for the device. Replies: Re: Signaltap - Crashing when attaching .sof file Hi, May I know what is the reason that you are attaching sof file in step 3 since you already program the sof file in step 2? May I know if you have another PC to test the same thing?
