| *** yorick has joined #tomu | 15:18 | |
| yorick | so if I run the blink example and then talk to it with wishbone-tool, wishbone-tool ends up defunct and lsusb stops working until I replug the fomu | 15:20 |
| yorick | known issue? | 15:20 |
| yorick | (it works with the micropython and the usb-cdcacm) | 15:20 |
| yorick | xobs: I think you might be the only one who knows | 15:21 |
| xobs | yorick: I need to pull in a full USB stack into the blink example. | 15:31 |
| yorick | also, is it supposed to only blink red? | 15:32 |
| yorick | hmm no, it doesn't do that with the real toolchain | 15:38 |
| yorick | (but it still doesn't do wishbone) | 15:38 |
| *** Stormwind has quit IRC | 15:48 | |
| mithro | yorick: which blink? | 16:06 |
| yorick | mithro: from the fomu-workshop | 16:07 |
| yorick | but I blame my self-compiled toolchain | 16:07 |
| mithro | yorick: the RISC-V blink? | 16:07 |
| yorick | yeah | 16:07 |
| yorick | the ones from other people do actually blink different colors | 16:08 |
| yorick | so I'm compiling riscv32-none-elf-gcc8.3 now | 16:08 |
| mithro | https://twitter.com/GregDavill/status/1164515676041764864?s=20 | 16:09 |
| mithro | yorick: I wonder if that is your problem... | 16:09 |
| yorick | oh yeah, looks like it | 16:09 |
| mithro | yorick: make sure you compile with multilib support | 16:09 |
| yorick | mithro: I ran into that and just switched to riscv32 | 16:09 |
| mithro | https://twitter.com/GregDavill/status/1164514482275508224?s=20 | 16:10 |
| yorick | mithro: yeah, so no im | 16:11 |
| yorick | is it rv32i? | 16:12 |
| yorick | (yes) | 16:12 |
| mithro | yorick: I think @xobs is learning why I ship the tools inside LiteX-BuildEnv and refuse to support using stuff outside that :-) | 16:15 |
| yorick | mithro: I don't have /usr/lib, so I have to run the toolchain in a chroot env now, which is really annoying | 16:20 |
| yorick | mithro: also I'd like to build arbitrary nix packages :D | 16:21 |

| xobs | yorick: So I justn oticed that I wasn't properly generating USB string descriptors. Can you try updating valentyusb? Just cd into "deps/valentyusb", run "git checkout master; git pull origin master" | 17:30 |
| xobs | https://github.com/im-tomu/valentyusb/commit/7d06457b301966ea3135b52318578ef84e9b9d19 | 17:30 |

| xobs | Turns out I was forgetting to include the first two bytes of the string in the length calculation. | 17:30 |
| xobs | I don't know if that's causing compatibility issues, but it's concievable that's the source of some of the issues. | 17:33 |
