| xobs | Just an informal survey -- how many people here have tried Foboot v2.0.3 and/or circuitpython? | 00:11 |
|---|---|---|
| xobs | (Specifically, Circuitpython on Fomu). | 00:11 |

| CarlFK | me! | 00:44 |
| CarlFK | I have v2.0.2 on my fomu if that counts for anything | 00:45 |
| xobs | CarlFK: The only change between v2.0.2 and v2.0.3 was that I fixed the IRQ storm, so it should work on your Intel machine now. Thanks for reporting that bug! | 00:53 |

| TomKeddie | xobs: I just put v2.0.3 on 8 of the evt1 boards you left at teardown. It seems to work well. I do see quite a number of initial boot failures though - pressing the reset button fixes this. Not sure if this is hw specific though, seems to happen on all of them. I tried touching up the pll reset code but made no difference. I'll try circuitpython all 8 now. | 03:07 |
| TomKeddie | Digging in a little more, even though the led doesn't blink, the usb is attempting to connect. See https://pastebin.com/5nNEe7pz Again this is evt1 not sure if that is relevant. I've re-reworked all the boards and I think they're good but you mentioned p/s issues at one point. | 03:11 |
| tpb | Title: [3048609.704997] debugfs: Directory '10' with parent 'devices' already present! - Pastebin.com (at pastebin.com) | 03:11 |
| xobs | TomKeddie: That's concerning. Thanks for the report. | 03:14 |
| xobs | Weird that it's trying to connect but the LED doesn't blink. | 03:15 |
| xobs | It literally sets up the LED before anything else, including trying to connect to USB: https://github.com/im-tomu/foboot/blob/master/sw/src/main.c#L211 | 03:16 |
| tpb | Title: foboot/main.c at master · im-tomu/foboot · GitHub (at github.com) | 03:16 |
| xobs | Which means either it's actually working but immediately trying to reconfigure with a bad image, or it's failing to configure at initial poweron. | 03:18 |
| TomKeddie | I tried my hacker board, circuitpython boots fine - it's like a miracle, all those usb descriptors! I do get some errors when I do lsusb -d 1209:5bf0 -v | 03:31 |
| TomKeddie | probably something you haven't got to yet. | 03:32 |
| TomKeddie | can't get device qualifier: Resource temporarily unavailable | 03:32 |
| TomKeddie | can't get debug descriptor: Resource temporarily unavailable | 03:32 |
| TomKeddie | Once I build my openvizsla I'll be able to help you morre. | 03:32 |
| mithro | TomKeddie: are you running as root? | 03:32 |
| TomKeddie | no but I have the udev rules in place, I'll try as root. | 03:33 |
| TomKeddie | Same errors (Hi Tim). | 03:33 |
| TomKeddie | Sorry I wasn't very clear there, I get pages of output from lsusb PLUS those errors. | 03:36 |
| TomKeddie | Here is the full output, the errors are inline about 40 lines from the end. https://pastebin.com/hCT2pm8V | 03:37 |

| xobs | I'd imagine those errors are due to speed issues in tinyusb. The SPI flash really could use a lot of optimization. | 03:42 |
| xobs | I'm mostly concerned about foboot not coming up -- if that doesn't work, then people can't update their boards. | 03:42 |
| TomKeddie | Ack, this is on linux 5.3.0-19. | 03:45 |

| TomKeddie | xobs: I think I found something interesting. It's something to do with the order in which the pins make contact with the connector. I have the evt1 plugged into a short extension cable, if I unplug/plug the extension cable from the pc and leave the evt1 alone then it comes up every time. If I unplug/plug the evt1 it fails frequently. I'm not sure whether you can reproduce this. I'll try to make a small video tomorrow. | 05:03 |
| xobs | Hmm... That's very good information. I did make the PCB slightly wider in EVT2+ because I noticed it could slide back and forth and not make good contact. | 05:06 |
