Support for Terasic DE1-SoC board with Cyclone V

[sedwards-lab]

The Terasic DE1-SoC board has a Cyclone V on it. Specifically, a 5CSEMA5F31C6 connected through an onboard usb-blasterII

Here's the two-line patch to add support for this board:

Incidentally, the FPGA is second on the JTAG chain, which the tool seems to handle correctly:

index 0:
    idcode   0xba00477
    type     ARM cortex A9

Also, your instructions for running quartus_cpf for converting .sof to .svf gave me an error (bad arguments). Here's what worked for me with Quartus Prime 21.1.0:

quartus_cpf -c --operation p -g 3.3 --freq 24.0MHz lab1.sof lab1.svf

I don't know how to create a private branch that could turn into a pull request

Thanks for these informations.

For svf the correct line is

quartus_cpf -c -q -g 3.3 -n 12.0MHz p project_name.sof project_name.svf

As mentioned here. But using an .rbf it's a bit faster to load.

To create a PR:

1. you have to fork this repository
2. clone your fork
3. git checkout -b nameOfYourBranch
4. apply modification + git add files + git commit -m "message" + git push
5. in github page create a PR.

Thanks again!

Now the board is officially supported. So I can close this issue.
