pdp7 | anyone know of what instructions I could follow to try using yosys+vpr on the Arty Atrix7-35T instead of Vivado? | 13:44 |
---|---|---|
pdp7 | 13:44 | |
pdp7 | I'm hoping I could do Linux-on-LiteX-Vexriscv without Vivado | 13:44 |

kgugala | @pdp7 you have a few options here | 14:00 |
kgugala | you can grab this PR https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1320 | 14:00 |
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) | 14:00 |
*** benelson has quit IRC | 14:01 | |
*** benelson has joined #symbiflow | 14:01 | |
*** benelson has quit IRC | 14:02 | |
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 | 14:03 |
*** benelson has joined #symbiflow | 14:03 | |
kgugala | this will build all the required parts of the toolchain (architecture definition etc) and in the end will build the bitstream | 14:03 |
kgugala | this may take some time | 14:04 |
kgugala | and remeber to set export VPR_NUM_WORKERS=$(nproc) | 14:04 |
kgugala | (this significantly speeds up the flow) | 14:04 |
kgugala | the second option is to generate the binary toolchain with "make install" | 14:05 |
kgugala | "make install" is added in this PR https://github.com/SymbiFlow/symbiflow-arch-defs/pull/1252 | 14:06 |
tpb | Title: Add make install target by kgugala · Pull Request #1252 · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 14:06 |
kgugala | then you can use the binary toolchain to generate the bitstream | 14:06 |
*** benelson has quit IRC | 14:07 | |
kgugala | there is even initial support for the binary toolchain in edalize https://github.com/SymbiFlow/edalize/tree/symbiflow | 14:07 |

pdp7 | @kgugala: thanks, I will try it out! | 15:22 |
*** Bertl_zZ is now known as Bertl | 15:26 | |
ZirconiumX | There's also experimental support in daveshah's nextpnr-xilinx | 15:40 |
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) | 15:42 |
