| pwarren | well, had a crack at the tomu-bootloader stuff on github.com/im-tomu. | 12:01 |
|---|---|---|
| pwarren | openocd does display differently if it's connected correctly, and appears to do _something_, can someone post the full output of what it's supposed to do? | 12:02 |
| pwarren | I flashed it, but still no worky on USB in my macbook hardware running linux. | 12:04 |
| pwarren | nothing appears in dmesg that is. | 12:04 |
| cyphar | it should tell you that "flash succeeded" or something like it | 12:18 |
| cyphar | I only just managed to get my own rPI working | 12:18 |
| cyphar | but for some reason my superglued wires aren't working (unsurprisingly) | 12:18 |
| cyphar | alright my flasher now works | 12:32 |
| cyphar | the output should look like | 12:32 |
| cyphar | pastebin.com/W7kP720X | 12:33 |
| NTU | I had a got at a 3D printed mounting sled, I don't think it's going to work. | 15:23 |
| NTU | It needs to be nearly as thin as the metal on a typical USB-A plug | 15:24 |
| NTU | Could file down the sides of the version +0.2 PCB, though | 15:25 |
| NTU | (Had a go, that is) | 15:30 |
| cyphar | NTU: the sled tim gave you is a bit too thick | 15:33 |
| cyphar | you just need to shave it slightly | 15:33 |
| cyphar | because it was designed after the prototype PCB thickness, which is thinner than the version you got at LCA | 15:34 |
| cyphar | ultimately just use some paper to jam it in if you're just testing | 15:34 |
| NTU | Yeah, I expect so. If there was a 3D model in https://github.com/im-tomu , I didn't see it, but I was just trying to make one with Blender and Cura on a https://printrbot.com/project/play/ https://en.wikipedia.org/wiki/Fused_filament_fabrication | 15:38 |

| NTU | Thinnest walls it can do is about 0.8mm (two thicknesses of 0.4mm), so yeah, a flat shim is probably simpler. | 15:41 |
| cyphar | the problem with a flat shim is that it covers the LEDs | 15:49 |
| cyphar | the reason the sled has a gap is so that you can add epoxy to stick the sled to the side of the board with the chips -- sealing away the solder pads forever | 15:49 |
| NTU | Ah! | 15:56 |
| NTU | Does that mean I have missed seeing an existing sled model? I was just going from the image in the slides | 15:56 |
| cyphar | oh, right. I have one with me and tim had a bag of them | 15:56 |
| cyphar | they look like thin rectangular prism which is hollow and has had two sides removed | 15:57 |
| cyphar | so there's a gap at the back and top | 15:57 |
| cyphar | github has a 3d view of https://github.com/im-tomu/tomu-hardware/blob/master/case/tomu_case.stl | 15:58 |
| tpb | Title: tomu-hardware/tomu_case.stl at master · im-tomu/tomu-hardware · GitHub (at github.com) | 15:58 |
| NTU | Ah. Sensible enough spot, just didn't spot it with https://github.com/im-tomu?&q=stl (maybe that's a content search?) or browsing. | 16:01 |
