conda.exe: cannot execute binary file

[just4give]

Hi,
I am trying to install FPGA Toolchain on Mac Catalin 10.15.7. I created a folder ~/Documents/symbiflow and set thant as INSTALL_DIR

Then as per readme I executed
bash Symbiflow_v1.3.1.gz.run from a folder when I downloaded the execution file. But I am getting following error.

As a result conda sub-directories are not loaded in the installed directory. Any idea how to resolve this issue?

I am seeing the same issue too (on Raspberry Pi OS).

hi @charkster

you are installing https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh - as the name suggest this is conda binary for Linux on x86_64. Raspberry Pi has ARM CPU. It cannot work

In general there is no prebuilt toolchain for ARM. However, I've seen somebody running the toolchain on rPI, so it is doable - you'd need to rebuild the required tools - namely Yosys and VPR (the rest is Python or bash scripts).

Also the flow requires Python3 (Python2 is not supported)

@kgugala Thanks for pointing this out. I will do the install on x86 Ubuntu.

@charkster to use it on RPi, you would have to build the tools from source, as @kgugala mentioned.

We have done this, the instruction below should be able to help you if you want to go this route:

@coolbreeze413 Thank you very much!!

[charkster]

@coolbreeze413 I have everything working except qlfasm (which comes from the conda flow and installs the x86_64 version). Would you know how to build or download qlfasm? Thanks. I needed to update my pp3_cells_sim.v and pp3_cells_map.v files for the new definition of qlal4s3b_cell_macro in eos-s3.

Try this for RPi 3:

Similar to
https://github.com/optimuslogic/pygmy-dev/blob/main/tools/tools-setup.txt

but using an older version of arch-defs for symbiflow

@gadepall Thanks!! that is just what I needed. Works great.
