Error during QSYS Generation: sequencer/sequencer.elf not found

As discussed in the email:

The main issue is that Nios II currently does not support WSL2, as mentioned here.

Therefore, you need to install WSL 1 and use this version.

To do that use the following steps.

• Open the start menu and type Turn Windows features on or off

• In the window that appears, click on Windows Subsystem for Linux and, when prompted, restart your PC.

• Open a command prompt as administrator and type wsl --list –verbose. You should get something like the following:

PS C:\Users\gxxxxxs> wsl --list --verbose

NAME STATE VERSION

* Ubuntu Stopped 1

If the version is 2, then continue to the next step. Otherwise, you can skip the next step.

• If the version is 2, type wsl --set-version Ubuntu 1 where “Ubuntu” is the name of the distribution from the previous step. You should get something like this:

PS C:\Users\gxxxxxs> wsl --set-version Ubuntu 1

Conversion in progress, this may take a few minutes.

The operation completed successfully.

Now, if you type wsl --list –verbose again, you should have “1” under the “VERSION” column.

• Type wsl -u root to enter the Ubuntu terminal and issue the following commands:

o apt update

o apt install wsl dos2unix make build-essential

Wait until the installation finishes.

After that, open Quartus and try generating the IP again.

For Linux, make sure that the 32-bit libraries are enabled and the build-essential package has been installed

sudo dpkg --add-architecture i386

sudo apt update

sudo apt install build-essential

Make sure the following packages are installed:

• g++

• gcc

• make

• libc6-dev

• dpkg-dev
