**** BEGIN LOGGING AT Mon Mar 28 02:59:56 2022 Mar 28 11:35:56 * bradfa looks at USB 4 spec... yeah, no way in hell anyone produces an IP block that can do USB 4 correctly and without a 1000 page errata list in the next 5 years. Mar 28 11:37:18 * bradfa will be seriously impressed if Intel's 3rd generation of USB 4 host controllers actually do things correctly (ie: I'm saying their first 2 tries will fail miserably), nevermind the USB 4 device side IP blocks or dual role or any of the tunneling junk Mar 28 11:37:46 I think the Apple M4 has usb4 ? the alternative is hooking up some pcie to usb4 bridge Mar 28 11:38:20 I mean, usb4 is largely based on thunderbolt, so it's not like it's all done from scratch Mar 28 11:38:26 but still Mar 28 11:39:22 apple M1 I mean Mar 28 11:39:35 zmatt: does it? I can't keep up with tech news anymore... Mar 28 11:40:09 oh, it does! Mar 28 11:40:53 at least with Apple no one will ever see the errata list, they can keep it secret and make it look like they did it right, owning the silicon and the OS all in-house Mar 28 11:40:59 hehe Mar 28 11:41:20 you mean chips HAVE BUGS? *shocked pikachu face* Mar 28 11:41:37 I look forward to the great jobs program which will be synopsis' USB 4 dual role controller IP block Mar 28 11:41:55 many software engineers will send their children to college on that one Mar 28 11:42:58 "roles" are fuzzy with usb4, it even supports host-to-host networking Mar 28 11:43:26 yeah, and the whole time sync and routing and spanning tree and... Mar 28 11:43:33 "USB4 by itself does not provide any generic data transfer mechanism or device classes like USB 3.x, but serves mostly as a way to tunnel other protocols like USB 3.2, DisplayPort, and optionally PCIe. While it does provide a native Host-to-Host protocol, as the name implies it is only available between two connected hosts; it is used to implement Host IP Networking." Mar 28 11:44:54 it's like someone said, "You know what's great and super complicated?! USB! What can we combine it with to make it even more confusing? Networking! Video displays! Other versions of USB! PCIe! And if anyone else has any good ideas on how we can ensure our own jobs for the next decade please write them and place them in this box here outside my office." Mar 28 11:45:25 * bradfa writes down, "Make the cabling even more complicated and confusing for normal people. HDMI cannot be best at this!" Mar 28 11:45:40 I mean, like, given the prior existence of Thunderbolt 3, it kinda sorta makes sense for usb to usurp it Mar 28 11:46:00 and actually reduce the number of incompatible things Mar 28 11:46:02 zmatt: it just would've made sense for that to happen when USB went to 3.0 Mar 28 11:46:30 I don't recall why that didn't happen, seems like Intel was leading both Mar 28 11:47:03 I guess, if usb3 had simply used pcie as the new transport Mar 28 11:47:06 Also, seems like a big missed opportunity to have gone optical early and solved many other problems back then, too Mar 28 11:47:08 instead of making a new one Mar 28 11:47:29 optical is a no-go, they wanted passive adapters Mar 28 11:47:33 to usb2 Mar 28 11:47:45 https://arstechnica.com/technopaedia/2008/05/thunderbolt/ Mar 28 11:47:52 I knew I read this long ago! Mar 28 11:48:34 yeah, Thunderbolt originally had nothing to do with usb Mar 28 11:48:39 Thunderbolt 3 is where the real mess started Mar 28 11:50:01 because using the same connector for different incompatible things is obviously a good idea and surely won't create confusion for normal users Mar 28 11:50:02 https://www.theregister.com/2007/09/19/idf_usb_3_announced/ Mar 28 11:50:30 heh, interesting Mar 28 11:51:09 well, that didn't happen Mar 28 11:51:27 everything old is new again! Mar 28 11:52:40 but yeah, if you want a SoC with real USB 4 support, and not just the USB 3.x rebranded kind, you're probably going to have to sign up for a millions/year contract with a big boy silicon vendor and sign some crazy looking NDAs Mar 28 11:53:06 or just wait for Intel to come out with something and beg them to sell it to you Mar 28 15:06:24 hai i wanted to do tunneling in beaglebone black to remote server. but am beginner in the configuration side of it. so can any one please guide me to get to know the things. Mar 28 15:07:59 wireguard may be of interest (and its kernel module is already included in the beaglebone's standard kernel I think) Mar 28 15:09:56 (see wireguard.com for documentation) Mar 28 15:10:00 how to use that by doing the service manner while booting up the board. please share me the reference. Mar 28 15:12:33 ehh, there's a bunch of ways you could do that, though I don't really have time to go into details right now (I'm at work) Mar 28 15:33:51 in here it not detailing the tunnel method. and the configurations. Mar 28 15:41:07 let me know if any one knows please Mar 28 15:54:07 With the stock bbb, you need to hold a button down to boot from the SD card instead of the eMMC, correct? Mar 28 16:38:16 No. I am pretty sure you need to the hold down the Boot Button/S2 on the board to boot to eMMC. Mar 28 16:40:52 That is only if the board has a SD Card in it too. Mar 28 16:42:39 Unless something has changed recently or in the last year, that is how I managed to use the eMMC image over SD image w/ a SD Card in the slot while having two images, i.e. one on the eMMC and one on the SD Card in its slot on the BBB. Mar 28 18:48:10 vvn: that's how my bbb behaves, after a power cycle, after a reset it will use the same boot medium again Mar 28 18:50:11 but then I started with bbb only last may, so maybe it changed last april? 😎 Mar 28 19:26:52 Hmm. That is neat. I never noticed that fact. Thank you for sharing this info. Mar 28 20:21:03 You can also put a boot configuration on eMMC that will try to boot from SD card first, that's IMHO the most convenient setup. Mar 28 20:54:11 in uboot? Mar 28 20:55:43 like if one was to use a build env. for booting the board, e.g. ____-ng or Buildroot? Mar 28 21:22:43 Yes, buildroot. I think it is the default, last time I was lazy and just copied U-Boot over from the SD card to the eMMC, and it worked. Mar 28 21:24:21 That was in January, I set up a bbb to water some plants. Mar 28 21:31:56 Ha. nice. Mar 28 21:32:18 There was an older script floating around the planet handling such a task. Mar 28 21:32:45 So, just using Linux to transfer the uboot commands can work too ( I guess ). Mar 28 23:32:09 vvn: powering on with the S2 button held down will cause the bbb to ignore the bootloader on eMMC (if any) and always use the one from sd card Mar 28 23:32:57 (and it will keep doing that until next power-cycle, the button isn't checked at reboot) Mar 28 23:33:32 vvn: however, the bootloader on eMMC will normally still prefer booting the system on sd card, if any, over booting from eMMC Mar 28 23:33:48 so usually it'll just boot from SD card when one is inserted, the button is not needed Mar 28 23:35:12 however, if the system on sd card is too different from the one on eMMC, the bootloader on eMMC may not be compatible with the sd card and fail to boot it (or worse, boot it but ignore some settings in /boot/uEnv.txt, causing weird problems) ... that's when the S2 button comes in use Mar 28 23:35:27 yes I was about to say that it depends on the bootloader Mar 28 23:35:42 but thank you, it answers my question! Mar 28 23:35:45 also useful if you somehow bork the bootloader on eMMC Mar 28 23:36:10 or if you want to be really sure it either boots from SD card or not at all Mar 28 23:37:33 starblue: that's actually the default yes Mar 28 23:37:50 starblue: for the normal bb.org images anyway, dunno buildroot Mar 28 23:38:50 set_: ehh, you're very confused. if you power on with the S2 button held down it will _never_ boot from eMMC Mar 28 23:39:41 (ignoring some really weird scenarios, like having an sd card inserted with just a bootloader on it but no linux system) Mar 29 00:30:03 Oh. Mar 29 00:30:04 Okay. Mar 29 00:30:44 Sorry vvn. Mar 29 00:30:58 I made an error in understanding the spewed it out. Mar 29 01:05:28 pass TRUST in the USA if flying your BBBlue! Mar 29 02:48:32 Speakin' of flyin' the BBBlue, any more revelations on the home front for gettin' this BBBlue in the air? Mar 29 02:55:42 Dang it. It may be a lost cause for me but I guess I will try again...BLAH! **** ENDING LOGGING AT Tue Mar 29 02:59:57 2022
