Help #2

[kmezynski]

I got repetitive issue, while doing @rw1nkler LiteX - Zephyr setup from his repository: https://github.com/antmicro-labs/2d-gpu/wiki/LiteX---Zephyr-tutorial

I'm using Ubuntu 18.04, so far I've installed all the prerequisites up to section: Prepare basic bit-stream, where I got stuck at command ./arty.py --with-ethernet. No matter what I tried to do, the reuslt was the same error:

ModuleNotFoundError: No module named 'liteiclink'

All the repositories were installed to the directory /home/kamil/Git/<repository_name>

My ~/.bashrc file looks following:

export PATH="${PATH}:/tools/Xilinx/Vivado/2019.2/bin"

export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/migen"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litedram"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/liteeth"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/liteiclink"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litejesd204b"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litepcie"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litesata"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litescope"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litesdcard"
export PYTHONPATH="${PYTHONPATH}:/home/kamil/Git/litex-zephyr-build/third-party/litevideo"

We couldn't solve this problem together for a few weeks, although I triple checked all the prerequisites and consulted with my friends whether they got the same issue. I'd be grateful for any kind of help.

Have you tried my repository? https://github.com/rw1nkler/litex-zephyr-build
Or this is just coincidence of names? @kmezynski

[kgugala]

@kmezynski I have updated the guide with installation of the missing packages. Basically run:

pip3 install git+https://github.com/enjoy-digital/liteiclink
pip3 install git+https://github.com/enjoy-digital/litex

before you start the build.

[kmezynski]

@rw1nkler Yes of course, I've tried to run this command on both litex and repository of yours.

[kmezynski]

@kgugala It helped in some way.. there's another problem with riscv toolchain:
OSError: Unable to find any of the cross compilation toolchains
I've installed RISC-V as it was described in section riscv toolchain. I've noticed, that after sudo make install I got make: Nothing to be done for 'install'.

[kgugala]

@kmezynski you don't have the toolchain binaries in your PATH. Please add the the directory where you installed the toolchain to the PATH and it should work

[kmezynski]

@kgugala I've tried it before by adding repository to PATH in various combinations and it didn't work.
export PATH="${PATH}:/home/kamil/Git/riscv-gnu-toolchain

[rw1nkler]

1. You have to add the path to the directory containing the toolchain binary.
2. If you are using my repo, the direnv can set all the environment variables for you. This is working, I'm using this repository on at least two different machines. Have you completed all the instructions from the README file? If you have problems with it we can organize the meeting.

[kmezynski]

@rw1nkler Wow everything went so smooth now... probably I should have listened to your tip from Help 1 (issue #5), instead of installing everything manually.

[rw1nkler]

Great! Seems like you almost did it manually, so now you should understand how this automated repo works. If you check your .envrc and .envrc.local you will find most of your manual work with paths and environment variables. (and their correct versions)
