make error

[kidonglee]

Dear Guys,

I am following the sequences in the page "https://www.cl.cam.ac.uk/~jrrk2/docs/docs/".
But I have a problem with the step of "Produce an FPGA Bitstream".
I have an error messages while building FPGA bitstream, as below.
With 'make nexys4_ddr_rocket', I also have the same message.
FYI, my environments are as follows,

• Branch : lowrisc-chip-ariane-v0.7
• OS : Ubuntu 18.04
• Xilinx : 2018.2

Are there any one who knows the solution on this problem?
Please help.
Thank you in advance.

Best Regards,

It looks like you downloaded an incomplete repo, suggest you delete your work area and start again from scratch.

Dear Jrrk2,
As I mentioned above, I follow the sequence of "https://www.cl.cam.ac.uk/~jrrk2/docs/docs/".
So, I cloned the branch 'lowrisc-chip-ariane-v0.7', as follow,

git clone -b ariane-v0.7 --recursive https://github.com/lowrisc/lowrisc-chip.git lowrisc-chip-ariane-v0.7

Do you mean that this branch is incomplete?
And could you please let me know how I download it?
Thank you very much.

Best Regards,

[wsong83]

Use the right clone command does not guarantee a success clone.
One of the usual reasons could be a time-out disconnection before a full clone due to slow or unstable internet connection.
What you can try is going into the cloned repo and repeatedly updating all submodules if the clone failed.

[jrrk2]

If you look at your log you can see that it failed inside the buildroot target. This target builds Linux and the userland from separately downloaded sources. This seems to be the step that failed and if it happens again with a clean tree then this is outside of LowRISC control. You should be able to find a pre-compiled root filing system in the release area of GitHub, but this usage is for users who are familiar with our previous releases and is outside the scope of support that is possible from this forum.
