Bitstream Compilation Error for 122_88 projects.

[wptaylor]

Description of the setup:

• Device: N/A
• SD card image: N/A
• Application: led_blinker_122_88, sdr_reciever_122_88
• Other relevant information: Development setup followed as in Development machine notes. Major variable difference is the Hypervisor method: I used Hyper-V instead of VirtualBox.

Description of the problem:

Compilation of the bitstream for led_blinker_122_88 and sdr_reciever_122_88 fails at synth_1 immediately following impl_1.

Seems not to be a dev environment issue as led_blinker compiles consistently without issue.

impl_1 runs in both cases for significantly longer than other steps (2+ mins for led_blinker, 20+ minutes for sdr_receiver).

synth_1 runme.log is clean, with no ERRORs. impl_1 runme.log does not exist.

Have not attempted with most recent release. Will see if that fixes functionality.

Steps to reproduce the problem:

1. Clone active GitHub repo.
2. Run make clean <led_blinker_122_88 or sdr_receiver_122_88> all

Same behaviour with make NAME=sdr_receiver_122_88 PART=xc7z020clg400-1 bit as specified verbatim here. Same behaviour when run as root.

Tried with the most recent release (20240204) for led_blinker_122_88 and got the same behaviour. Terminal output of the erroneous stage is pasted below. Here is the runme.log file from tmp/led_blinker_122_88.runs/synth_1/.

If it crashes without errors, it may be that there is not enough memory in your virtual machine or the problem is indeed with Hyper-V.

If you are using Windows, then it is also possible to use Windows Subsystem for Linux (WSL) and install Ubuntu Linux via the application store.

Update: sdr_receiver compiles as intended. Is there a large memory requirement difference between 122_88 projects and others? If not, then it would seem to imply a specific issue with those compile chains (either in general or with my setup).

In any case, will try with a more powerful workstation/VM shortly. Will also try using WSL instead.

[pavel-demin]

I have just checked that the memory usage is quite similar (between 2.5 and 3 GB) when building led_blinker and led_blinker_122_88. If I remember correctly, the virtual machine should have at least 4 GB of memory to build all projects.

[wptaylor]

Interesting. I had allocated 8GiB+ (dynamic allocation) so I would be surprised if that was the issue. Will be checking with a Linux machine soon.

Issue is fixed when using a full Ubuntu Linux boot with higher specs. Still unsure cause of error. Will try and determine if I get time later.
