| xobs | 'tis a silly place. | 01:05 |
|---|---|---|
| xobs | I haven't even done anything past USB FS. HS seems weird enough, even though it's standard by now. And I don't even know if I have any SS devices. | 01:06 |
| * xobs yells at cloud | 01:06 | |
| xobs | Also, I moved to a newer version of vexriscv, and strangely USB has stopped working. I'll have to look into that today once I have the USB LA back. | 01:46 |
| *** emeb has left #tomu | 02:23 | |
| xobs | Strange. Now it works. | 04:20 |
| xobs | Super suspicious. | 04:20 |
| xobs | Can someone please try the v1.3 tag I just pushed? To make sure I'm not going crazy here. | 04:21 |

| futarisIRCcloud | xobs: v1.3? Ok, let me test. Can I run it on a unit without flashing it? | 05:15 |
| xobs | futarisIRCcloud: I suppose you could. Load `top.bin` as a program, and "lsusb" ought to indicate that it's v1.3. | 05:15 |
| xobs | The joys of having the program in the bitstream. | 05:16 |
| futarisIRCcloud | [24881.064119] usb 1-1.1: Product: Fomu Bootloader (0) v1.3 | 05:30 |
| xobs | Looks good to me! | 05:30 |
| xobs | Thanks for checking on that. | 05:31 |
| futarisIRCcloud | No problems. I guess if it's running as a program, and we try to upload, it'll overwrite itself... | 05:32 |
| xobs | That's true, but since it's running from a virtual ROM in the bitstream, that's actually not so much an issue. | 05:33 |
| futarisIRCcloud | Seems to be enumerating fine. | 05:34 |
| xobs | That's using a newer vexriscv which has, among other things, illegal instruction trapping. | 05:35 |
| xobs | Luxurious. | 05:35 |
| futarisIRCcloud | I re-enumerated them all the way round... | 05:41 |
| futarisIRCcloud | [25533.674198] usb 1-1: new high-speed USB device number 127 using xhci_hcd | 05:41 |
| futarisIRCcloud | [25533.830329] usb 1-1: New USB device found, idVendor=0409, idProduct=005a, bcdDevice= 1.00 | 05:41 |
| xobs | That looks like a hub? | 05:42 |
| tnt | btw, I found a "stress test" for my core was to run `lsusb -v -d 0409:005a` 100x in a loop as fast as possible. Found a couple of lockups that way ;) | 05:46 |
| xobs | Foboot seems to be able to handle it! | 05:52 |
| xobs | Though the USB Beagle locks up. | 05:52 |
| tnt | lol | 06:00 |
| tnt | xobs: you ran it as root (or with appropriate perms) ? (else it doesn't re-do the controls xfer, it just used cached info) | 06:00 |
| xobs | Yeah, ran it under "sudo". I see the traffic now. The Micropython instance had some trouble, though... | 06:01 |
| futarisIRCcloud | xobs: Yep. I was replugging the hub (with 4 FOMUs) all the way round... fomu enumerates about 80-90% of the time, but most times eventually comes up. | 06:03 |
| xobs | futarisIRCcloud: I wonder why it doesn't enumerate... | 06:03 |
| futarisIRCcloud | xobs: Probably something in the hub. | 06:04 |
| tnt | do you properly stop responding to addr 0 when you get assigned one ? | 06:06 |
| xobs | Good thinking. I'll leave it doing "while true; do fomu-flash -r; sleep 0.6; if ! lsusb -d 1209:70b1; then echo "Didn't enumerate!"; break; fi; done" and see what happens. | 06:06 |
| tnt | xobs: you need -v in there so it queries all attributes. | 06:07 |
| tnt | oh wait nm, you're forcing re-enum with flash, | 06:07 |
| xobs | tnt: I'm just making sure it enumerates at all. The question I have is: does it successfully enumerate every time after it's reset. | 06:08 |
| xobs | It ought to be deterministic. | 06:08 |
| xobs | But you know how communication protocols are... | 06:08 |
| tnt | yeah. If you have a hub you should throw one in there. I find that "root hubs" on the PC directly are much better behaved than what you get on a external hub with other stuff attached. | 06:09 |
| futarisIRCcloud | I've found that too. | 06:09 |
| tnt | (it's still valid USB, so it should work but it can highlight stuff) | 06:10 |
| xobs | wtb cheap hub | 06:10 |
| xobs | Belkin will have to do. | 06:13 |
