**** BEGIN LOGGING AT Wed Oct 02 02:59:57 2019 Oct 02 06:30:15 probally any of the circuitco mfg ones Oct 02 09:15:10 hi guys Oct 02 09:15:35 I could not find IoT image for the X15 board Oct 02 13:22:33 @quola: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Stretch_IOT_Snapshot Oct 02 16:51:28 Hi everyone Oct 02 16:53:04 Is any chance to do something with that board http://agansk.ru/tech/wp-content/uploads/2017/11/D3_6.jpg Oct 02 16:53:32 It wos ASIC mother board Oct 02 16:53:38 It was ASIC mother board Oct 02 16:55:13 But now I wont to do something with that board, for exmple use as pc Oct 02 16:56:28 but it hasn't HDMI framer and I think a need to connect LED matrix to pins Oct 02 17:14:19 I'd rather find non-display use-cases for that type of board Oct 02 17:15:02 there are many things you can do. Oct 02 17:23:14 well, if you really want to display something ... a fullscreen clock surely works ... even unaccelerated ;) Oct 02 17:57:55 krikz: looks like this is a version with NAND flash rather than eMMC, which is going to make things annoying Oct 02 17:58:28 it also doesn't have the serial console header soldered on it seems Oct 02 17:58:51 tbr: you can connect displaylink USB-to-monitor to it Oct 02 17:58:57 typically these things also have a limited am335x variant like the am3352, which means no PRU Oct 02 17:59:10 tbr: should work, with that new displaylink driver which is DRM-capable, you can even render into it Oct 02 17:59:20 guys, why would you want to connect a display to it? Oct 02 17:59:26 just use it headless Oct 02 17:59:34 like most uses of beaglebones are :P Oct 02 17:59:37 I'm just suggesting a way around this displayless-ness Oct 02 18:00:24 you can also use e.g. SSD1306 or similar over SPI with tinydrm Oct 02 18:01:00 but the lack of HDMI framer isn't a problem that requires a solution, it's rare to have any use for a display on the BBB Oct 02 18:01:34 it's definitely not the biggest problem with this board Oct 02 18:01:58 the NAND flash is Oct 02 18:02:45 it means it uses a custom DT Oct 02 18:03:07 also, it doesn't have an USB host port... so there goes your USB-to-monitor idea :P Oct 02 18:04:59 it also seems to have neither a 5V barrel jack nor usb device port, so it can only be powered via the P9 header Oct 02 18:05:44 zmatt: nand flash is easy, put UBI+UBIFS on it, run some cronjob to rescan the UBI even now and then, and you're done Oct 02 18:05:58 it'll probably be more reliable than the eMMC Oct 02 18:06:23 if it's booting from the NAND , well, you cannot protect the MLO, but anything after MLO can be in UBI Oct 02 18:06:40 you probably want the cronjob to scan the MLO and reinstall it if it detects ECC errors Oct 02 18:06:50 and keep a good copy of the MLO in the UBI for that ^ purpose Oct 02 18:06:51 krikz: overall, while I'm sure it's possible to find uses for this thing, it's probably more hassle than it's worth Oct 02 18:07:21 zmatt: as for the USB, the AM335x should have an MUSB, maybe it's just not brought out on the board ? Then the SPI tinydrm still applies ;-) Oct 02 18:07:57 Marex: I'm not saying it's an impossible obstacle, but it means a standard image won't work and you need custom stuff to get it to work, hence knowledge of that custom stuff (which you evidently have, but krikz may not) Oct 02 18:08:14 zmatt: that's why I'm sharing it here Oct 02 18:08:34 maybe it's useful for someone Oct 02 18:09:09 yes if you look at the photo both usb ports are still in the pcb layout but the connectors and various support components (e.g. the usb power switch) are not placed Oct 02 18:10:01 zmatt: maybe a soldering iron can help here ? Oct 02 18:10:30 it all depends on how much time one wants to sink into this thing, and how one values one's time Oct 02 18:11:00 :) Oct 02 18:11:10 I suspect that you'd need to assign very little value to your time to make getting this board to work worth it over buying a normal BBB Oct 02 18:11:41 a board like this is only worth it when you have use for a large quantity of them... like antminer had :P Oct 02 18:12:25 :) Oct 02 18:12:47 plus the coolest feature of the BBB (PRUSS) is probably missing (can't tell from this photo, but that's what I remember from previous boards like these)... which alone makes the whole endeavour less worthwhile Oct 02 18:13:04 zmatt: why would a missing PRU be a problem ? Oct 02 18:13:22 because then you can't use PRU ? Oct 02 18:13:45 zmatt: isn't that a circular reasoning ? Oct 02 18:13:55 zmatt: if there is no use for PRU, missing PRU is no problem Oct 02 18:14:36 but PRU is the biggest highlight the BBB has over other low-cost ARM boards. without it, the SoC is pretty meh Oct 02 18:14:46 heh Oct 02 18:14:46 it doesn't make it useless Oct 02 18:15:24 it just excludes a category of interesting uses (and krikz wanted to "do something" with the board) Oct 02 18:15:59 I guess the usefulness of the board then depends on the definition of "something" Oct 02 18:16:51 e.g. for writing FOSS driver for the powervr GPU, one doesn't need display O:-) Oct 02 18:17:03 yes and the vaguesnss implies he's searching for uses, so that means excluding a bunch of the coolest projects is a bad thing Oct 02 18:17:17 the AM3352 doesn't have a GPU either Oct 02 18:17:25 oh Oct 02 18:19:40 just found a photo of the topside of this board, it's indeed an AM3352: https://ae01.alicdn.com/kf/HTB1sYo8SXXXXXbLXpXXq6xXFXXXR/Antminer-L3-L3-IO-board-BB-Black-BeagleBone-Black-BB-Black-BB-board-AM3352BZCZ100-Development-Board.jpg Oct 02 18:22:05 the ram is also different Oct 02 18:24:49 it's 256 MB (2Gbit) DDR3 (not L) Oct 02 18:25:31 basically nothing about this board is BBB, it's just a custom AM335x-based board Oct 02 18:25:56 it'll require a custom u-boot, custom DT Oct 02 18:27:31 and I suspect that if krikz had the knowledge to deal with that, he wouldn't have asked the sort of question he did) Oct 02 18:28:24 1 i wont to install debial image Oct 02 18:28:47 2 i wonto connect display Oct 02 18:28:57 debian* Oct 02 18:29:58 krikz: my recommendation is just to throw this board away unless you want to invest a very large amount of time to learn how to bring up a custom board like this (I suspect there's also no schematic available, but that's not insurmountable) Oct 02 18:30:06 so first of all learn how to build a custom debian image then ... Oct 02 18:30:30 once you have finished that, connect a display and find out that it is useless ... Oct 02 18:30:37 first of all you'd need to solder on the serial console header to be able to debug boot issues Oct 02 18:31:08 then fllow zmatt's advice and throw it away ... and be heppy that you learned how to create a custom debian image along the way Oct 02 18:31:14 lol Oct 02 18:31:17 :) Oct 02 18:33:02 Thank you! Oct 02 18:33:03 re custom debian image, use multistrap, should be rather straightforward Oct 02 18:33:39 well, you still need to have a custome u-boot and DT to inject ... not *really* straightforward Oct 02 18:33:39 oh and technically you probably need to know the pcb trace lengths of the traces to the DDR3 ram to configure correct leveling in your custom u-boot, but maybe they kept those the as in the original BBB, you may want to compare the BBB's (open) pcb design with the traces visible on the topside of this custom board Oct 02 18:33:59 maybe you can get away with using the u-boot that's presumably already on NAND flash Oct 02 18:34:25 but now I can connect to this board through ssh Oct 02 18:34:43 zmatt: maybe they even provide the sources, as it's GPL ? Oct 02 18:34:47 hah, yeah maybe, good luck with that :D Oct 02 18:35:12 krikz: then probably you shouldn't replace the on-board image if you want to keep it in a functional state Oct 02 18:35:23 once you start to replace anything, it'll be a looong journey to get it working again Oct 02 18:35:37 yep Oct 02 18:38:07 also I would not recommend even trying to run a graphical desktop environment on this thing, even if you get a display connected.... a desktop environment already doesn't run very comfortably on a normal BBB, and this custom board has only half the amount of RAM Oct 02 18:39:41 you should also verify which pins are used for NAND (e.g. by dumping the pinmux on the running system)... with a bit of bad luck they're using some pins that conflict with the LCD controller, in which case you're kinda fucked Oct 02 18:40:04 it's possible my show-pins utility might work on this thing => https://github.com/mvduin/bbb-pin-utils/#show-pins Oct 02 18:42:14 ah lol it also lacks the power, reset, and S2 buttons **** BEGIN LOGGING AT Thu Oct 03 01:17:07 2019 **** ENDING LOGGING AT Thu Oct 03 01:44:01 2019 **** BEGIN LOGGING AT Thu Oct 03 01:47:37 2019 **** ENDING LOGGING AT Thu Oct 03 02:59:57 2019
