| lkurusa | Hi! | 08:31 |
|---|---|---|
| lkurusa | i have a tomu from LCA2018 with DFU flashed | 08:31 |
| lkurusa | i've tried to get the U2F token working, but for some reason whenever I do `u2f-host -aregister` on my machine I don't see any blinking LED on the tomu | 08:32 |
| lkurusa | nor does touching either buttons do anything | 08:32 |
| lkurusa | lsusb reports Tomu as "Bus 003 Device 024: ID 0483:cdab STMicroelectronics" | 08:32 |
| lkurusa | any pointers would be appreciated :) | 08:33 |
| xobs | Hi lkurusa (IRC) . The bootloader you flashed at LCA2018 didn't automatically enter Toboot. I got enough confused feedback that I changed that behavior. | 08:33 |
| xobs | You should probably update to v2.0-rc7 (install toboot-boosted.dfu from https://github.com/im-tomu/tomu-bootloader/tree/master/prebuilt) | 08:34 |

| xobs | To actually enter toboot, which will allow you to upload new software, you'll need to force entry into it by shorting out the two outside contacts. See https://github.com/im-tomu/tomu-bootloader#using-toboot | 08:34 |

| lkurusa | oh fun | 08:35 |
| lkurusa | do i just dfu flash that .dfu file? | 08:35 |
| xobs | Yep. When you look at available devices (`dfu-util -l`) after flashing that file, it should list "toboot v2.0-rc7" in the available devices. | 08:36 |
| lkurusa | Thanks, let me try that. | 08:37 |
| lkurusa | how do i enter DFU mode again? >< | 08:38 |
| xobs | Short out those pins: https://github.com/im-tomu/tomu-bootloader#using-toboot | 08:39 |
| tpb | Title: GitHub - im-tomu/tomu-bootloader: Bootloader for the EFM32HG Tomu Board (at github.com) | 08:39 |
| lkurusa | that's way harder than it looks | 08:46 |
| lkurusa | yay flashed the bootloader | 08:51 |
| lkurusa | so now i've updated the bootloader, i restart the tomu and then i just flash the u2f firmware? | 08:51 |
| xobs | Correct. | 08:51 |
| xobs | Note that the u2f firmware, by default, auto-boots. | 08:51 |
| xobs | So if you want to upgrade it in the future, you'll need to do the shorting-the-pins trick again. | 08:52 |
| lkurusa | that's fine with me | 08:52 |
| lkurusa | i'll try flashing the u2f.bin now | 08:52 |
| lkurusa | ok this is broken now | 08:57 |
| lkurusa | the same result, so i shorted out the two pins again, it's flashing green/red but doesn't show up in dfu-util | 08:57 |
