| mithro | daveshah: Heyo - it looks like the latest nextpnr is throwing an exception on the LiteX-BuildEnv targets | 15:52 |
|---|---|---|
| daveshah | mithro: do you have a backtrace? | 15:53 |
| mithro | Just logging a github issue now | 15:53 |
| daveshah | Thanks | 15:54 |
| mithro | https://github.com/YosysHQ/nextpnr/issues/343 | 15:56 |
| daveshah | mithro: do you have the netlist/Verilog that is triggering this? So I don't have to set up the whole of buildenv | 15:58 |
| mithro | daveshah: I'll see if I can find it, the build doesn't push the verilog output when it fails | 15:59 |
| daveshah | mithro: hang on, are you sure this is using latest nextpnr? | 16:24 |
| mithro | daveshah: Maybe? :-P | 16:25 |
| daveshah | I *think* the issue might be a version of nextpnr from a couple of months ago before the JSON format for parameters changed | 16:25 |
| daveshah | (strictly speaking nextpnr was broken before and Yosys just changed its behaviour) | 16:25 |
| mithro | 0.0.0_2155_g1ecf271 | 16:27 |
| daveshah | mithro: yeah that's pretty old | 16:28 |

| daveshah | mithro: that's not 1ecf271 | 16:29 |
| daveshah | I guess that you are building a newer nextpnr but not then using it for the gateware build | 16:30 |
| daveshah | maybe a conda issue | 16:30 |
| mithro | Hrm... I'm a bit confused.. | 16:30 |
| mithro | timvideos/nextpnr-ice40/0.0.0_2247_gc365dd1/linux-64/nextpnr-ice40-0.0.0_2247_gc365dd1-20191011_225942.tar.bz2 | 16:31 |
| daveshah | The build is definitely not a recent nextpnr - because I added statistics for LUT/FF/carry packing about a month ago | 16:31 |
| daveshah | e.g. `Info: 2494 LCs used as LUT4 only` | 16:31 |
| mithro | Yeah, looks like it didn't pick up the new version | 16:31 |
