| futarisIRCcloud | mithro: What do antmicro plan to do on the fomu? | 01:16 |
|---|---|---|
| mithro | Zephyr would be one thing | 01:21 |
| mithro | futarisIRCcloud: https://github.com/timvideos/litex-buildenv/pull/126 | 01:22 |
| tpb | Title: zephyr: Add build-zephyr.sh script. by mateusz-holenko · Pull Request #126 · timvideos/litex-buildenv · GitHub (at github.com) | 01:22 |
| mithro | xobs: we should get lto into litex upstream it seems to save space on the bios and stuff too... | 01:23 |
| mithro | https://github.com/enjoy-digital/litex/issues/139 | 01:23 |
| tpb | Title: Enable link time optimisation in builds · Issue #139 · enjoy-digital/litex · GitHub (at github.com) | 01:23 |
| mithro | futarisIRCCloud: https://github.com/timvideos/litex-buildenv/pull/127 | 01:24 |
| tpb | Title: scripts: Add Renode emulation support. by mateusz-holenko · Pull Request #127 · timvideos/litex-buildenv · GitHub (at github.com) | 01:24 |
| futarisIRCcloud | xobs: -flto does make a big difference | 01:26 |
| futarisIRCcloud | mithro: Have you tested this yet? I was about to do this, but got distracted by fomu working ... | 01:27 |
| mithro | futarisIRCcloud: I haven't tested at all | 01:33 |
| mithro | I also suggested the antmicro team reach out to you | 01:33 |
| mithro | My flight to Chicago for KiCon is just departing. Might be back later if I get wifi working | 01:34 |
| futarisIRCcloud | Ok. Enjoy KiCon. Be sure to catch up with Greg Davill. | 01:58 |
| pollo | hey, I was wondering: if I have a tomu with a program on it, what happens to that program if I update toboot? | 01:59 |
| pollo | is only the bootloader updated, or is the whole chip also wiped? | 01:59 |
| futarisIRCcloud | xobs: Are you planning on trying newer vexriscv today? ( https://github.com/SpinalHDL/VexRiscv/issues/70 ) | 02:16 |
| tpb | Title: No trap generated for `divu` on core without divide · Issue #70 · SpinalHDL/VexRiscv · GitHub (at github.com) | 02:16 |
| xobs | pollo: hi pollo, yes the way "booster" works is it loads itself as a normal program, and then overwrites Toboot. So it essentially wipes the chip. | 02:17 |
| xobs | futarisIRCcloud: I'm trying! But the build just hangs. | 02:17 |
| xobs | It's actually been hanging for 24 hours now. | 02:17 |
| xobs | I suspect it's in an infinite loop. But there's no way to prove that. | 04:13 |
| xobs | futarisIRCcloud: interesting, -flto only works with gcc 8.2.0. It doesn't work on 8.1.0 (it gives me the error "lto-wrapper failed") | 04:47 |
| futarisIRCcloud | xobs: Probably because of the version of binutils (being used with gcc) hasn't been updated... | 04:51 |
| xobs | I'm just using the toolchain from sifive. I updated my Windows build from 8.1.0 to 8.2.0, and it works now. So 8.1.0 must use some older version of binutils. | 04:52 |

| xobs | I just tagged v1.2.1, which seems to improve on handoffs from the bootloader to a running RISC-V program. micropython now works on the first try. | 05:46 |
| futarisIRCcloud | Cool | 05:47 |
| xobs | And I just published an updated version of micropython. I'm curious to know if people are still experiencing freezes. | 05:54 |
