**** BEGIN LOGGING AT Sun Mar 06 02:59:57 2022 Mar 06 08:05:27 well.... uhg. Mar 06 08:05:59 no dhcp, no static that I can see. no BT that I can see. uart is giving a constant CCCCCC at a slow rate Mar 06 08:06:18 is it possible the port is running 5v and not 3.3v ? Mar 06 08:06:21 Whiskey`: that means the eMMC is blank, bootrom is trying to find a boot device Mar 06 08:06:43 srsly Mar 06 08:07:06 it's unprogrammed Mar 06 08:07:20 I understand what you said Mar 06 08:07:46 the CCC is an attempt to perform xmodem boot via uart0 Mar 06 08:08:43 the boot order selected by the sysboot pins is { mmc1 (eMMC), mmc0 (typically μSD), uart0 xmodem, usb rndis } Mar 06 08:09:20 goodie. and since I ahvent read the docs much yet im going to assume from your list there that it doesnt do tftp Mar 06 08:09:44 usb rndis works by showing up as usb networking device and performing bootp/tftp boot via that Mar 06 08:10:29 ethernet netboot can be selected by setting sysboot2=0 Mar 06 08:10:34 wait no Mar 06 08:11:10 i can manage xmodem Mar 06 08:12:01 dust off 20 year old skills that are rusty as a car sitting in the ocean, but ill manage it. just kinda shocked it doesnt have anything onboard already Mar 06 08:12:31 I've never tried xmodem boot... I think it means you have to upload u-boot SPL via xmodem, u-boot.img via ymodem... and you may need compile u-boot with support enabled for this first Mar 06 08:13:25 I wouldn't bother with it, since even if you get u-boot in there that way, then what? Mar 06 08:13:30 well Mar 06 08:13:42 I guess if u-boot has ums support you could use that to flash eMMC Mar 06 08:14:18 the rndis tftp route sounds potentially easier to me, but that might just be because I have already done it Mar 06 08:14:47 welp lets RTD then Mar 06 08:14:57 RTD ? Mar 06 08:15:09 real bbb's dont seem to have the mini b port Mar 06 08:15:11 roll the dice Mar 06 08:15:17 yes they do Mar 06 08:15:47 it's the main way people connect to the bbb Mar 06 08:16:04 herm. ok the pic I see has some leds there Mar 06 08:16:11 it's on the bottom side Mar 06 08:16:45 aah Mar 06 08:16:56 you sure these boards are worth your time investment anyway? like, even if you get them fully working, they're still really crappy boards Mar 06 08:17:09 like, they lack almost all of the unique benefits of the bbb Mar 06 08:17:29 like, the am3352 has no PRUs enabled, you barely got any I/O Mar 06 08:17:49 when I am here its when my time has less value than when im doing other things Mar 06 08:18:18 it'll just be a low-spec arm linux board Mar 06 08:18:34 how much ram is on this thing anyway? Mar 06 08:18:44 or rather, what memory chip is on it? Mar 06 08:19:52 you'll probably also need to modify u-boot to even get it to boot on this board at all I just realized, unless they programmed the board identification eeprom to claim it's actually a BBB Mar 06 08:20:09 4ew17 d9pxv by micron Mar 06 08:21:34 okay, so they didn't change that Mar 06 08:21:59 there are a few diff revs and some are obviously used so ill crack those out of the cases and see how those do. Mar 06 08:22:28 is this like assets sold off from a failed company or something? Mar 06 08:22:49 well the brand name on it is still a very going company Mar 06 08:22:59 I have no idea why this stuff was at auction Mar 06 08:23:02 or a failed project of that company I guess Mar 06 08:23:58 the auction house didnt really want ot admit where it came from, they likely get people trying to get 'theri' stuff back Mar 06 08:24:30 which is odd, they know me, im not a huge spender but I im there a few times a month. Mar 06 08:24:37 did you ask the company? Mar 06 08:25:43 no, i dont think they would respond nicely Mar 06 08:28:03 for all the things i can imagine, its the ones I cant that keep me from asking them. Mar 06 17:44:26 Hello, my BBB died, at connecting to power I have only short blink of blue pwr led and then nothing,  I found on expansion header P9 pin 20 sda2 is shorted to ground , I suspected Capacitor C152 when I removed it i got to know it's good, does enyone meet such problem? Mar 06 19:55:16 zmatt: https://pastebin.com/yVPmbnAy Mar 06 19:55:22 a bit of progress Mar 06 20:01:24 welp now that is interesting Mar 06 20:01:41 its def doing ip bridging of bt to the ethernet Mar 06 20:01:53 popped a phone on and blamo it pulled a ip from my network Mar 06 20:08:01 Slamar: this usually indicates the SoC got damaged, typically by exposing an I/O pin to overvoltage Mar 06 20:10:15 Slamar: why would C152 be relevant? that doesn't make any sense Mar 06 20:10:26 that's just a power supply decoupling cap Mar 06 20:13:07 I don't have well electronic knowledge I tried because I found is shorted to ground, Mar 06 20:13:38 if it is shorted to ground then all of vdd_3v3a is shorted to ground Mar 06 20:13:47 Probably pin overvoltage may be possible because, step down dc dc burn Mar 06 20:14:01 which powering bbbb Mar 06 20:15:03 oofies Mar 06 20:15:40 I had a 48>24 dcdc go bad and dump 48v into gear. Nearly cried. Mar 06 20:23:08 !! Mar 06 20:23:34 I was just sad Whiskey` Mar 06 20:23:36 zmatt: can I /msg you the user manaul for these? i managed to find them Mar 06 20:23:51 Slamar: sure, you lost what, one bbb? Mar 06 20:24:05 But now is almost impossible to buy new one BBB in relative price Mar 06 20:24:18 here at the office we pretty much got a cemetary full of dead BBBs accumulated over the years, lol Mar 06 20:24:21 Yes one bbb Mar 06 20:24:24 Slamar: I lost a bit over 4k in gear Mar 06 20:25:43 zmatt is it trash for you? Can you send some of them  to be a spare parts from it ? Mar 06 20:26:13 I will pay for sending and ex per kg of it Mar 06 20:26:44 Whiskey` what kind of gear Mar 06 20:26:46 ? Mar 06 20:26:53 I mean, they're not mine, I'd need to ask Mar 06 20:26:56 Slamar: wireless ISP Mar 06 20:27:02 $dayjob Mar 06 20:27:42 what kind stuff do you using ubiquiti/mikrotik/mimosa? Mar 06 20:27:50 what distance Mar 06 20:28:48 all three but we dropped mimosa. they just dont have the bandwidth Mar 06 20:28:59 ubnt for outdoor, tiks for indoor Mar 06 20:29:05 zmatt I don't want to bother you to much at first I should ask from what country are you? Mar 06 20:29:11 netherlands Mar 06 20:29:12 uh whats the offtopic rules here? Mar 06 20:29:54 Im from poland so there shouldnt be problem to send it Mar 06 20:29:55 Whiskey`: *shrug* Mar 06 20:30:29 so basic dont be a butt and lets on topic chat prevail Mar 06 20:31:31 something like that Mar 06 20:33:18 Did you tried make a complaint about the product? Mar 06 20:33:39 what? Mar 06 20:33:46 ? Mar 06 20:34:21 who are you asking? Mar 06 20:34:22 Whiskey` warrantity about your damaged gear Mar 06 20:34:28 ah Mar 06 20:35:00 Slamar: ha no. they wouldnt cover replacing their device, not even willing to talk aobut damaged gear Mar 06 20:35:12 "you must have installed it wrong" Mar 06 20:35:45 zmatt Can you share some knowledge how to check bbb board in correct way to get what is damaged Mar 06 20:37:02 no, no idea how you'd diagnose that. the symptom you're seeing (brief blink of power led) indicates one of the power supply rails is shorted to ground, causing the pmic to go into overcurrent protection while sequencing the power-up Mar 06 20:38:14 in practice, the most common reason for this is the SoC being damaged by overvoltage to an I/O (which have a tendency to cause an internal short from supply rail to ground inside the I/O cell), but it could also be something else Mar 06 22:43:52 BBB! Mar 06 22:44:56 Did anyone see the latest twitter feed from beagleboard.org? Mar 06 22:45:18 I got a reminder but I then proceeded and it sent me on a journey to see the latest-greatest. Mar 06 22:45:42 But! Oh. Oh well. It did not show anything. Mar 06 22:51:55 I found it! Mesa Driver! Mar 06 22:52:28 it is not the first one even though the latest-greatest is on the 4th of this Month. I have been fooled for less. Mar 06 22:57:39 Oh! Mar 06 22:58:11 What would be the best Cape so far to handle an electronic gate w/ infrared sensors and a chain? Mar 06 22:58:37 I am not familiar w/ infrared so far for whatever reason. Mar 06 23:00:37 I noticed that the MotorCape handles 12v DC Motors. This is a plus/bonus/whatever but would I need just GPIO onboard the remainder of the header pins to handle such a sensor? Or...would I need PWM for the infrared sensors? Mar 06 23:02:41 I do not have the hardware now, i.e. as it is plastered to a bigger piece of something else in the middle of nowhere. Mar 06 23:03:18 But! The black box as it comes is easily accessible. Mar 06 23:06:06 GPIO...okay. But, I bet the chip on it is not just gpio controllable. I will see later, i.e. watch them hornets. **** ENDING LOGGING AT Mon Mar 07 02:59:57 2022
