Linux Qsys Now "platform designer", ALT_PLL Altera FPGA IP doesn't save, crash.

@Serqetry, last year when I posted the above, I was working on the University of Colorado Boulder's FPGA specialization on Coursera. A couple things I learned. Ultimately, Altera (now Intel) do not do a good job of supporting Linux. They just don't. Other tools within the Intel tool chain became maddeningly difficult to get work (if ever) under Linux. Don't even getting me started on Nios. In the end, I spent days of time trying to get Linux to work. Honestly, I switched to Windows. And, Windows just worked. If you have the option to switch to a Windows PC with Intel tools, I would. If you don't, you're going to face an uphill battle as this is will likely be the first of many challenges. I know this doesn't answer your question. But, I wouldn't wish my journey last year (before I switched to Windows) on my worst enemy. Sorry.

I'm actually on Quartus Prime Like 23.1 for Windows and the same exact thing happens here (so it's not just a Linux issue).

I applied the modification above (the file was located in C:\intelFPGA_lite\23.1std\ip\altera\sopc_builder_ip\altera_avalon_mega_common )

but it did not help

You can get to the PLL Reconfiguration but when you click Next, the wizard closes and the PLL you were building disappears from the design.

I'm on Quartus Prime Lite 23.1 on Linux too, on the same Coursera class. I managed to configure the clocks by attaching gdb to the wizard, setting a breakpoint on the crashing function, and forcing return of two frames always when it gets called.

First, to enable attaching gdb to a running proces, run as root:

# echo 0 > /proc/sys/kernel/yama/ptrace_scope

Run the PLL wizard from Quartus. In a separate terminal, find the PID of the wizard process (the number from the second column):

$ ps aux | grep mega_altpllq

Attach gdb to it (substitute the proper pid), set up a few things, and resume the wizard:

$ gdb -p 260525

(gdb) set confirm off

(gdb) br _ZN27ALTCLKLOCK_CLK_SETTING_PAGE29should_enable_disable_controlERK10UI_QSTRING

(gdb) c

Proceed with the wizard. When switching to the (3) Output Clocks page, or on any modification of the data therein (which you need a handful of times), the breakpoint triggers. Switch to the terminal with gdb and do

(gdb) return

(gdb) return

(gdb) c

When you're done with the wizard, you can exit the gdb and close the terminal.

I also applied the change to the if in the .tcl file. I don't know if it's needed.

I agree with the sentiment that this is a fun class and that the tooling is a huge pain.
