| oter | I have a couple of litedram novice questions. 1/ does anyone have an example, or reference to litedram’s native use (not wb or axi)? 2/ on versa_ecp5, is there a way to skip or disable training so as to not require the vexrisc cpu at all (in exchange for some performance loss maybe)? Thanks! | 03:30 |

| sajattack[m] | does only the sifive toolchain support ilp32? mine from arch linux packages doesn't | 05:30 |

| sajattack[m] | idk why I'm suddenly having the ilp32 problem. looking at github, that's been in for 10 months, guess I should just use the sifive toolchain | 07:48 |
| sajattack[m] | but I'm surprised it worked previously | 07:48 |

| Claude | daveshah: compile on pi4 went trough. https://twitter.com/Claude1079/status/1234029585081274368 | 09:05 |
| daveshah | Nice! | 09:05 |
| Claude | thinking about offering a diy kit.. | 09:05 |
| Claude | but funny, even on a lowly pi4 the whole process (compile&download) is way faster than for a similar design using quartus on an i7@5GHz :P | 09:07 |
| sajattack[m] | I installed the sifive toolchain and it's still complaining wtf | 09:46 |
| sajattack[m] | `riscv-sifive-elf-ld: unrecognised emulation mode: abi=ilp32` | 09:47 |
| sorear | ld doesn't take -mabi options | 10:00 |
| sorear | ld options are completely different from gcc options and if you're doing ld $(CFLAGS) you are not going to have a good time | 10:00 |

| 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 | I'm hoping I could do Linux-on-LiteX-Vexriscv without Vivado | 13:44 |
| keesj | well | 14:43 |
| keesj | it works for the epc board and such and I think people are working on xilinx but I don't know the exact status | 14:44 |
| keesj | the joy is that .. aside from installing the xilinx tools the rest works pretty much the same hence... | 14:45 |

| sajattack[m] | the build system is kind of convoluted idk why it's LD'ing CFLAGS | 19:12 |
| sajattack[m] | ok maybe I traced it | 19:19 |
| sajattack[m] | I think maybe it's $CPUFLAGS on this line https://github.com/enjoy-digital/litex/blob/e2aebb427ece793537e64f28cc3193704e7be782/litex/soc/software/common.mak#L59 | 19:21 |

| sajattack[m] | if I remove it I get another error, `plugin needed to handle lto object` | 19:33 |
