| esden | whee! that was a fun stream! now I need to check why my setup's USB is so broken :D | 03:02 |
| esden | motwok: I want snake on TOMU!!! | 03:03 |
| esden | The archive of the first ~2hours of today's Tomu stream are up. The rest is still processing. https://www.youtube.com/watch?v=p4ASXFTsWLo | 03:05 |
| esden | somehow the internet connection crapped out and caused a stream splittage :D | 03:05 |
| esden | and the remaining part of the stream archive is now live too! https://youtu.be/7GKfuTod59U | 03:16 |

| xobs | michft: What command are you giving it? It should just be "dfu-util -D [program.bin]" | 04:00 |
| michft | sudo dfu-util -D build/u2f.bin | 04:06 |
| xobs | That should do it, yeah. Try restarting Tomu? Unplug it and plug it in again? | 04:36 |

| SergeiG | michft, looks like you need to upgrade bootloader first | 05:10 |
| SergeiG | michft, simply pulling latest toboot, flashing it with dfu-util and then flashing u2f.bin works for me | 05:16 |
| michft | will try | 05:17 |
| michft | Worked!!! | 05:20 |

| *** michft has quit IRC | 06:53 | |
| esden | But I am very happy to report that flashing the bootloader worked super easy using Black Magic Probe... totally out of the box and without configuration! :D | 06:56 |
| esden | and yes I needed to set 'mon tpwr enable' to provide power to the target ... obviously :D I do not have your newest board xobs so I have put together the v0.2 instead. As I had an unpopulated board of that version from mithro... :D | 06:59 |
| esden | I might actually order the v0.4 from oshpark in 0.8mm thickness and put that together for laughs and giggles :D | 06:59 |

| xobs | esden: I'm curious how it'll turn out. The case is 0.6mm, and I'd like to make it even thinner. But plastics. | 07:47 |
| *** nrossi has joined #tomu | 08:46 | |
| xobs | I haven't tagged v0.4 yet because I haven't made it yet. Still, it's considered "RC" status, in that, barring any terrible catastrophies, that's what we'll go with. | 08:58 |

| kyaputen | esden yes BPM works like a charm (well until you brick your tomu) | 15:53 |
| kyaputen | btw, mithro, are you still interrested in the CDC gcc port? I fear I will brick more units trying to make it work :( | 15:53 |
| mithro | kyaputen: Now we have xobs' dfu upgrade utility, I'm much less interested in the other bootloader -- I would still /love/ it to work from another example point of view but I guess you could just do examples instead | 17:15 |
| mithro | kyaputen: I would be very surprised if you actually "bricked" a Tomu -- how are you determine it was bricked? | 17:16 |
| kyaputen | I can't address it over swdp | 17:23 |
| kyaputen | I tried to put Reset to ground, plug it in while reset etc. | 17:23 |
| kyaputen | nothing works | 17:23 |
| kyaputen | I'm also surprised bc I think it should be recoverable from the docs | 17:24 |
| kyaputen | but somehow I'm not able to do it :( | 17:24 |

| florian | Hi, I ordered a couple of tomus on crowd supply because I would like to switch an existing project using similar hardware to tomu. I ordered a couple of weeks ago, but shipping will still take some time. Does anyone have a good suggestion for a similar board I could use for development until then? | 18:07 |
| florian | Or is the QEmu emulation a good alternative? | 18:12 |
| mithro | florian: The QEMU emulation is pretty basic -- its not really enough to do anything useful | 18:15 |
| mithro | florian: if you contribute to the project in some way I'm happy to send you some of the v0.3 boards from my stash | 18:15 |
| *** xobs has quit IRC | 18:17 | |
| florian | mithro: Sorry for the late reply. I'll have a look. Any pointers? I'm working with rust/cortex-m-rtfm, I would be happy to contribute samples and any other bits that emerge there. | 19:18 |
| mithro | florian: rtfm? | 19:20 |

| mithro | florian: Were in the world are you? | 19:24 |
| florian | yeah, the name is a bit unfortunate... ...but the ideas are quite cool. I'm in Denmark. | 19:26 |
| mithro | florian: you could also build your own like esden did recently | 19:35 |
| florian | Yes I might manage. I've built a fs-bb48 (similar board, https://www.gniibe.org/memo/development/fs-bb48/fs-bb48-idea.html) successfully, but only with a lot of help from the hardware guys at the institute I worked at at the time. That's why I was thinking of buying a dev board and porting to tomu once I receive mine. | 19:42 |
| tpb | Title: Flying Stone Bare Bone 48 (at www.gniibe.org) | 19:42 |
| esden | florian: yeah assembling the board by hand was really easy, these are really very few parts :D | 20:21 |
| esden | should look up the timestamp of the moment where I reflow the board with my hot air rework station... | 20:22 |
| esden | mithro: ohh I see xobs is not around at the moment ... I should probably dig into it myself and see if I can get the blinky examples working again somehow... | 20:23 |
| esden | just so others know, I have flashed the blinky example onto a v0.2 board using the dfu bootloader. Now the board blinks furiously as if one of the buttons was continously pressed and I can't connect over SWD to the board any more to wipe it :( | 20:24 |
