<pdp7> anyone know of what instructions I could follow to try using yosys+vpr on the Arty Atrix7-35T instead of Vivado?
<pdp7>
<pdp7> I'm hoping I could do Linux-on-LiteX-Vexriscv without Vivado

<kgugala> @pdp7 you have a few options here
<tpb> Title: Add Base Litex minitest capable of running Linux on Vexriscv by tmichalak · Pull Request #1320 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com)

<kgugala> follow the regular arch-defs flow (clone, make env, make all_conda) and in the end go to xc7/tests/soc/litex/base and run make baselitex_arty_bin
benelson has joined #symbiflow
<kgugala> this will build all the required parts of the toolchain (architecture definition etc) and in the end will build the bitstream
<kgugala> this may take some time
<kgugala> and remeber to set export VPR_NUM_WORKERS=$(nproc)
<kgugala> (this significantly speeds up the flow)
<kgugala> the second option is to generate the binary toolchain with "make install"
<kgugala> "make install" is added in this PR https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1252
<tpb> Title: Add make install target by kgugala · Pull Request #1252 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com)
<kgugala> then you can use the binary toolchain to generate the bitstream
benelson has quit [Ping timeout: 255 seconds]
<kgugala> there is even initial support for the binary toolchain in edalize https://github.com/SymbiFlow/edalize/tree/symbiflow
<tpb> Title: GitHub - SymbiFlow/edalize at symbiflow (at github.com)

<pdp7> @kgugala: thanks, I will try it out!
Bertl_zZ is now known as Bertl
<ZirconiumX> There's also experimental support in daveshah's nextpnr-xilinx
<daveshah> I can't guarantee the VexRiscv linux still works with that (I know Rocket Linux does and VexRiscv Linux used to but I haven't tried for a while)
