I've installed the SymbiFlow toolchain as described here, but when I want to run the counter_test example, I get an error:

❯ TARGET="arty_35" make -C counter_test
make: Entering directory '/home/oguz286/Projects/FPGA/symbiflow-examples/xc7/counter_test'
mkdir -p build/arty_35
cd build/arty_35 && symbiflow_synth -t top -v /home/oguz286/Projects/FPGA/symbiflow-examples/xc7/counter_test/counter.v -d artix7 -p xc7a35tcsg324-1 -x /home/oguz286/Projects/FPGA/symbiflow-examples/xc7/counter_test/arty.xdc 2>&1 > /dev/null
cd build/arty_35 && symbiflow_pack -e top.eblif -d xc7a50t_test 2>&1 > /dev/null
make: *** [Makefile:53: build/arty_35/top.net] Error 1
make: Leaving directory '/home/oguz286/Projects/FPGA/symbiflow-examples/xc7/counter_test'

I've tried running the counter example in the symbiflow-arch-defs repository, and that worked fine. I'm on Arch Linux if that's important somehow.

Hi @GuzTech , can you alter the Makefile and rerun (or rerun the last command explicitly), and capture the stdout/stderr to a file instead of having it sent to /dev/null, and post the error and surrounding text here?

Sure! I've removed the > /dev/null part of the part that runs symbiflow_pack and now I get this error:

❯ TARGET="arty_35" make -C counter_test
make: Entering directory '/home/oguz286/Projects/FPGA/symbiflow-examples/xc7/counter_test'
cd build/arty_35 && symbiflow_pack -e top.eblif -d xc7a50t_test 2>&1

@GuzTech , I need to call in the experts :)

@kgugala , @acomodi : Unexpected command-line argument '@VPR_ARGS@' -- any ideas?

Ah I found the problem. Because I first tried the symbiflow-arch-defs repository, there apparently were some environment variables set that messed things up. I've opened a new terminal and now that step works.

Now I run into the same problem described in #108 but I'll look into it tomorrow. Thanks for the help :)

EDIT: It does product the bitstream and it works just fine on the board.
