**** BEGIN LOGGING AT Thu Sep 01 02:59:57 2022 Sep 01 06:17:21 eBay! Sep 01 06:17:29 That is where all good things go to be replaced. Sep 01 06:17:41 Outside of that idea... Sep 01 06:17:56 BBAI-64 and ROS! Sep 01 07:19:35 Nope. Sep 01 07:37:06 wouldn't be surprised if the "beaglebone black" they purchased for cheap isn't even actually a beaglebone Sep 01 10:44:44 Hi everyone, I am working on a project that uses a beaglebone black wireless but mine seems to have broken. Ignoring the wireless features, how interchangable are the beaglebone black and beaglebone black wireless? Sep 01 10:52:09 Guest6317: fully Sep 01 10:52:42 Guest6317: well, that and the bbb has a mini-usb connector while the bbb-wireless has a micro-usb connector ... but the correct cable is included in both cases anyway Sep 01 11:05:38 Thanks! Sep 01 11:18:16 how to install software on beaglebone green Sep 01 11:18:59 i want to install minicom Sep 01 11:21:00 using apt, like any other debian system Sep 01 11:23:27 I did sudo apt-get install minicom Sep 01 11:23:55 but get sudo: apt‐get: command not found Sep 01 11:24:27 uhh, the "‐" in "apt‐get" is not a "-", it's some unicode character Sep 01 11:24:38 it should be "apt-get" instead (with a normal -) Sep 01 11:25:24 that is Sep 01 11:25:32 I'm guessing you copy-pasted apt-get from something that helpfully used unicode characters to make things look nicer :P Sep 01 11:26:24 I'm sorry but I didn't understand. write without - Sep 01 11:26:38 "sudo apt-get install minicom" Sep 01 11:27:04 yes i wrote that Sep 01 11:29:04 I can't even do anything with apt-get Sep 01 11:29:28 try just 'apt' without the '-get' they should be the same Sep 01 11:29:41 ie "sudo apt update" Sep 01 11:30:18 I did it right away but he does not allow it to be done - it gives errors Sep 01 11:30:36 Err:1 http://deb.debian.org/debian stretch InRelease Sep 01 11:30:36   Temporary failure resolving 'deb.debian.org' Sep 01 11:30:37 Err:2 http://repos.rcn-ee.com/debian stretch InRelease Sep 01 11:30:37   Temporary failure resolving 'repos.rcn-ee.com' Sep 01 11:30:38 Err:3 http://deb.debian.org/debian stretch-updates InRelease Sep 01 11:30:38   Temporary failure resolving 'deb.debian.org' Sep 01 11:30:39 Err:4 http://deb.debian.org/debian-security stretch/updates InRelease Sep 01 11:30:39   Temporary failure resolving 'deb.debian.org' Sep 01 11:31:16                      so I don’t know if it’s possible to install at least something on BBG Sep 01 11:31:29 Guest87: 1. stretch is obsolete, please reflash to at least debian buster first Sep 01 11:31:53 2. your beaglebone doesn't have an internet connection so it can't download any packages, easiest way to provide internet to it is by plugging it in via ethernet Sep 01 11:32:06 I have debian Sep 01 11:33:15 ok, I connected it to both the computer and the Internet Sep 01 11:33:40 "stretch" and "buster" are debian releases... debian 9 is called stretch, debian 10 is buster, debian 11 is bullseye Sep 01 11:33:54 debian 9 (stretch) is obsolete Sep 01 11:35:15 how to check what version of debian Sep 01 11:35:28 lsb_release -a Sep 01 11:35:29 bash: lsb_release: command not found Sep 01 11:35:35 I think éuname -aé Sep 01 11:35:41 sorry "uname -a" Sep 01 11:35:43 and you were getting a "command not found" error because the "-" in "apt-get" was some weird character, look closely: https://imgur.com/a/xxZvPJ0 Sep 01 11:36:01 Linux beaglebone 4.9.82-ti-r102 #1 SMP PREEMPT Thu Feb 22 01:16:12 UTC 2018 armv7l GNU/Linux Sep 01 11:36:12 jfsimon1981: uname only shows the kernel version Sep 01 11:36:32 Guest87: cat /etc/debian_version Sep 01 11:36:42 ok Sep 01 11:37:06 Guest87: it also showed "stretch" when you were trying to do apt update Sep 01 11:37:08 9.3 Sep 01 11:37:25 which, as I said, is stretch Sep 01 11:37:51 and how can i change it? Sep 01 11:39:00 download the latest official flasher: https://debian.beagleboard.org/images/bone-eMMC-flasher-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz .. write it to a microSD card (4GB or larger) using https://www.balena.io/etcher/ Sep 01 11:39:18 when you boot the beaglebone from that sd card, it will automatically wipe and reflash it Sep 01 11:39:29 (if you have any important files on it, make a backup of those first) Sep 01 11:40:29 yes thank you very much. I've been doing this several times already with only version 9 Sep 01 11:40:48 why with version 9 ? Sep 01 11:41:05 and after that apt -get should work? Sep 01 11:42:15 this is unrelated to that, apt-get (or apt) should work if your beaglebone has internet access (and you type it correctly, and do "sudo apt-get update" once before attempting to "sudo apt-get install") Sep 01 11:42:20 I don’t know why - I’m just learning and I saw a lesson that they do this .... I didn’t know that it was very important Sep 01 11:42:56 like, running debian stretch on a beaglebone is kinda like running Windows XP on a PC :P Sep 01 11:43:35 like, sure, you can do it, and people still do, but it's getting really old and it's not getting any updates Sep 01 11:44:15 Is it compatible with all versions of Linux? Sep 01 11:44:24 ?? Sep 01 11:44:37 I have linux beaglebone 4.9.82-ti-r102 Sep 01 11:44:58 "Linux" is just the name of the kernel, the heart of the operating system Sep 01 11:45:10 4.9 is also a very ancient version of that Sep 01 11:45:56 oops, I messed up - sorry (I'm still a beginner) Sep 01 11:45:56 I installed linux on my bbg and not debian Sep 01 11:46:47 linux is at the heart of a debian system Sep 01 11:47:24 like, "debian" describes the overall system, which includes the kernel (linux) and many other programs and files needed to make an actual usable system Sep 01 11:47:50 (there are also other linux-based systems, like Ubuntu and Android) Sep 01 11:47:57 when i insert a microSD card linux will not be erased? because i formatted it like that Sep 01 11:48:10 ???? Sep 01 11:48:45 you're very confused, and I no longer have any idea what you're trying to ask Sep 01 11:49:27 that is, will I still have the same version of Linux or not? I'm just interested in how it works, it doesn't matter to me which version Sep 01 11:50:09 the debian 10.3 image I linked above includes linux kernel 4.19.something Sep 01 11:50:32 the kernel can be updated like any other package on the system Sep 01 11:51:17 that is, when I install another version of debian, it also changes the version of Linux ???? Sep 01 11:51:17 4.19.94-ti-r42 Sep 01 11:51:42 the linux kernel is part of the debian system, it's just one of many software packages (albeit a quite important one) Sep 01 11:52:47 in conclusion: inside debian there are packages from a certain version of linux Sep 01 11:54:40 linux is a kernel, a core component that's at the heart of an operating system, like the engine of a car. people often also use the term "linux" to describe operating systems that are built around the linux kernel, debian is one of such operating systems Sep 01 11:56:02 operating systems built around the linux kernel are also called "linux distributions" or "linux distros" for short... debian is such a linux distro, but there are many others Sep 01 11:56:59 super thanks you helped me a lot. if not with a problem then with understanding Sep 01 11:57:00 I hope after updating debian I can finally install minicom :))) Sep 01 11:57:54 it looked like your main issues with attempting to install packages (besides the weird char in "apt-get") was the beaglebone not having working internet access Sep 01 11:58:59 in the new version of debian it should be? Sep 01 11:59:34 I already told you, updating to debian 10 is unrelated to your problem, it's just something you should do because debian 9 is severely outdated Sep 01 12:00:02 the error you showed indicates that your beaglebone does not have internet access Sep 01 12:00:21 without internet access, it can't download anything to install Sep 01 12:01:14 Would connecting to the internet help? i need to install minicom Sep 01 12:01:35 ethernet (not internet) Sep 01 12:03:37 easiest way to provide internet access to a beaglebone black is by connecting its ethernet to your internet router/modem. if you're connecting it via ethernet to your computer instead, and your computer has internet via wifi, then you'd need to enable something called internet sharing to share your PC's internet connection to the beaglebone Sep 01 12:04:20 anyway, I've got other things to do, maybe someone else can help if you have further questions Sep 01 12:04:25 I have BeagleBone GREEN!!! Sep 01 12:04:34 beaglebone green, black, same thing pretty much Sep 01 12:05:06 thank you so much and have a great day!!! Sep 01 12:05:28 what I just said applies to all debian systems running on some computer that only has ethernet and no wifi Sep 01 12:05:49 (e.g. most beaglebones) Sep 01 12:06:39 (hmmm, actually now that I think of it "most beaglebones" these days actually have wifi... well never mind that :P ) Sep 01 12:06:48 afk Sep 01 12:10:43 please tell me what exactly should I do to connect to the Internet via an ethernet cable. I have never connected like this. Sep 01 12:11:24 I connected my beagle to 1-computer 2-to ethernet cable Sep 01 12:11:25 right Sep 01 12:26:09 please tell me what exactly should I do to connect to the Internet via an ethernet cable. I have never connected like this. Sep 01 12:26:09 I connected my beagle to 1-computer 2-to ethernet cable Sep 01 12:26:10 right? Sep 01 12:37:54 I'm trying to send data to driver on BeagleBone Green via USB Serial Adapter. Sep 01 12:37:54 I'm connecting  adapter  to the GPIO pins of uart2 (I added all port data to the device tree) Sep 01 12:37:55 1. im openning configured minicom on pc, Sep 01 12:37:55 2.im connecting to bbg via ssh Sep 01 12:37:56 but when im writing in minicom symbols Sep 01 12:37:56 cat utilite on bbg side ,that wait to get data, dont get nothing Sep 01 12:37:57 where is i have problem? Sep 01 12:37:57 I'm new at this and I really hope for help Sep 01 12:41:49 I'm trying to send data to driver on BeagleBone Green via USB Serial Adapter. Sep 01 12:41:50 I'm connecting  adapter  to the  pins of uart2 (I added all port data to the device tree) on bbg and to pc Sep 01 12:41:50 1. im openning configured minicom on pc, Sep 01 12:41:51 2.im connecting to bbg via ssh Sep 01 12:41:51 but when im writing in minicom symbols Sep 01 12:41:52 cat utilite on bbg side ,that wait to get data, dont get nothing Sep 01 12:41:52 where is i have problem? Sep 01 12:41:53 I'm new at this and I really hope for help Sep 01 12:49:51 RachelM: is the baudrate configured the same on both sides? Sep 01 12:50:21 yes Sep 01 12:50:38 Guest87: don't send unsolicited private messages Sep 01 12:50:48 RachelM: is it a 3.3V TTL usb serial adapter? Sep 01 12:50:54 115200 Sep 01 12:51:42 Guest87: and I already answered the question you're asking, having to keep repeating things to you is getting rather tiresome Sep 01 12:54:31 RachelM: also, I'm not sure if catting a serial port works correctly, I think some terminal settings need to be configured after opening the port but before trying to read... not 100% sure about that though, it's been a while since I've worked with serial ports Sep 01 12:54:43 I think so i have cp2102 adapter Sep 01 12:55:10 RachelM: have a part numbe or a link to the product page or something? Sep 01 12:57:24 try: stty -F /dev/ttyS2 raw 115200 clocal -crtscts -ixon Sep 01 12:58:06 RachelM: also double-check that the pins are configured correctly using my show-pins utility: https://github.com/mvduin/bbb-pin-utils/#show-pins Sep 01 12:58:09 on beaglebone side? Sep 01 12:58:11 yeah Sep 01 12:59:55 show-pins should show "uart 2 rxd" for the receive pin in show-pins Sep 01 12:59:56 im configure pins in driver via data sheet Sep 01 13:01:12 not sure what you mean by that, but regardless of how you've configured the pins, it's good to verify that the pins are indeed setup correctly, and my show-pins utility is a convenient way to check this Sep 01 13:03:54 I used the program from the site https://alexrhodes.io/blog/post/22/ Sep 01 13:05:02 uhh. this is a tutorial on how to write a kernel driver? Sep 01 13:05:23 i do step by step how written on the site but not succesful Sep 01 13:05:47 you trying to learn how to write a kernel driver, or are you just trying to get a serial port working? Sep 01 13:05:59 because this is the former, not the latter Sep 01 13:08:08 my task to write uart driver on bbg and my code is based on the code of site Sep 01 13:08:48 and i want to check if it work well Sep 01 13:08:53 task? is this a homework project or something? Sep 01 13:09:10 final project Sep 01 13:09:59 if this is a final project, it sounds like perhaps you should be able to debug your own software? :P Sep 01 13:10:47 on the end of Sep 01 13:11:05 ... Sep 01 13:11:13 and you should certainly be better at asking questions... instead of coming in here asking for help with serial communication, when you were actually asking for help with getting a custom kernel driver working Sep 01 13:11:21 :P Sep 01 13:12:07 anyway, I've got things to do too... but good luck with your driver project Sep 01 13:12:47 i compiled and installed driver with device tree Sep 01 13:13:24 but i want to check if it work **** BEGIN LOGGING AT Thu Sep 01 13:56:37 2022 Sep 01 16:01:14 hi good day Sep 01 16:02:09 I just want to know if the BEAGLEBOARD-X15 is compatible with Android 12 Sep 01 16:04:20 looks like TI's AM572x processor sdk for android is for android 9 Sep 01 16:06:16 though I don't know if that means android 12 isn't compatible.... I don't really know anything about android myself, nor have I ever heard of someone running it on a beagleboard-x15 (which is pretty much identical to the processor board of the AM572x EVM) Sep 01 16:09:03 looking at TI's git repo, I'm getting the impression they stopped maintaining android for the am57x: https://git.ti.com/cgit/android/hardware-ti-am57x/refs/ Sep 01 16:09:23 oh there's even a bbx15-specific repo... it's equally dead though: https://git.ti.com/cgit/android/device-ti-beagle-x15/refs/ Sep 01 17:32:57 Helo Sep 01 17:33:07 Im sorry for the dely Sep 01 17:33:14 *delay Sep 01 18:54:28 hello all. I may have done a boo-boo and wiped the /dev/mmcblk1 on a beaglebone AI (I did this because that's the standard way of SD booting on a BBB). Now the beagle doesn't turn on. Sep 01 18:54:31 Is it bricked? Sep 01 18:59:01 no Sep 01 18:59:34 not sure if mmcblk1 is eMMC or SD card on the bbai Sep 01 19:00:18 I think you probably just wiped your sd card Sep 01 19:03:21 hmm maybe not Sep 01 19:03:28 mmcblk1 seems to be the eMMC here Sep 01 19:09:50 it appears the bbai boot order for bootrom prefers to load u-boot from SD card over loading it from eMMC, so there was no point in wiping eMMC anyway Sep 01 19:10:22 though if wiping eMMC caused it to no longer boot the sd card, that would seem to imply to me that your sd card doesn't actually have a (functioning) u-boot installed Sep 01 19:13:20 zmatt: Sept 1st snapshots are now posted... https://forum.beagleboard.org/tag/latest-images Sep 01 19:14:13 bbai: eMMC = mmcblk1, microSD = mmcblk0 Sep 01 19:14:17 Guest19: wiping eMMC is recommended for AM335x-based beaglebones if you want to use an SD card as primary boot device, because the AM335x bootrom can't be configured to prefer loading u-boot from SD card over loading it from eMMC... either eMMC is preferred over SD (default on all beaglebones that have eMMC) or eMMC is not consulted at all (which happens when you power up while holding down the S2 ... Sep 01 19:14:23 ...button) Sep 01 19:14:30 Guest19: this simply doesn't apply to the bbai Sep 01 19:17:24 Guest19: regardless, if the bbai doesn't boot your sd card, the logical conclusion is that your sd card isn't bootable Sep 01 19:18:07 and if it used to boot but no longer does after wiping eMMC, then the specific reason the sd card isn't bootable will be because u-boot is missing or damaged on the SD card Sep 01 19:18:36 (and you were unknowingly just relying on the u-boot installed on eMMC) Sep 01 19:18:57 actually, not "missing or damaged", just missing Sep 01 19:22:38 rcn-ee: in the readme, you may want to use e.g. "sudo systemctl disable --now nodered" ... the ".service" is redundant and the "--now" will also imediately stop the service (in addition to preventing it from booting at next startup) Sep 01 19:23:22 cool, didn't know about --now... updating.. Sep 01 19:24:26 and you probably also want to disable the associated .socket unit in that case, although that's also something you could arrange for in the .service unit itself Sep 01 19:25:14 we no longer do socket activation in nodered... Sep 01 19:25:39 ah ok Sep 01 19:25:49 it was something upstream didn't care about, and teh patch got more difficult, so it was dropped... Sep 01 19:26:13 (and it was slow...) Sep 01 19:27:33 yeah socket activation is more useful for sockets used by local services, since it means you may be able to avoid a strict dependency between services Sep 01 19:28:31 and for applications that dont take 30seconds to start.. looking at you code-server.. Sep 01 19:30:42 running the cloud version of vscode as a server on a beaglebone still seems insanity to be, compared to running vscode locally and using https://vscode-eastus.azurewebsites.net/docs/remote/ssh Sep 01 19:32:18 though lol wtf, "1 GB RAM is required for remote hosts, but at least 2 GB RAM and a 2-core CPU is recommended" ... WHY Sep 01 19:33:42 also why does google keep giving me that weird link as top result instead of the normal url https://code.visualstudio.com/docs/remote/ssh Sep 01 19:33:56 While being slow at startup, it does actually work 'decently'... it's not how fast cloud9 was.. but it actually loads.. Sep 01 19:36:44 also on am335x, we have to enable a swap file, to make it even load.. yeah for am335x it fills a checkbox, more a gimic.. on am57xx or bbai64 it runs pretty good.. Sep 01 19:37:07 please don't enable swap by default /o\ Sep 01 19:38:58 `2.965s dphys-swapfile.service` Sep 01 19:39:06 I feel like this void should be fillable by a tutorial on getting started with vscode (desktop version) + remote development via ssh Sep 01 19:39:26 https://www.irccloud.com/pastebin/57MeDoZG/ Sep 01 19:39:53 dphys-swapfile is directly tied to the bb-code-server package... Sep 01 19:41:37 thanks @zmatt. I will take a look at a known good SD card. Sep 01 19:41:58 Guest19: what image did you flash to your SD card? wondering why the bootrom didn't pick it up... Sep 01 19:42:35 Guest19: and how did you flash it? etcher.io ? or something else.. Sep 01 19:42:46 rcn-ee: good to know that disabling bb-code-server will thus also disable swap, but still I question whether you really want this "gimmick" as you described it to be enabled by default, particularly on AM335x images Sep 01 19:44:00 it's actually 'disabled' by default... user has to enable it..i think i worded the wiki wrong.. Sep 01 19:44:12 `#rfs_enable_vscode="enable"` it's disabled in the build script.. Sep 01 19:45:20 yeah, looking at the config files, arm64 is the only one with it enabled out of the box... `rfs_enable_vscode="enable"` Sep 01 19:47:46 There it is... back on Dec 29, 2021 https://github.com/RobertCNelson/omap-image-builder/commit/fef9dab055016411cf14be521b7bb6b8536e7c41 defaulting to enabled on arm32 was stupid.. forgot to update the wiki to 'opt-in/enable it'... Sep 01 19:48:50 @rcn-ee: used dd, and used bbai64-debian-11.3-xfce-arm64-2022-06-14-10gb.img.xz - I was able to mount it and confirm that the SD card is mounting. Sep 01 19:49:12 one note I would have is that the first partition isn't the boot partition, but I'm assuming that's just the way it is. Sep 01 19:49:25 Guest19: which board do you have "BBAI" or "BBAI64".... based on your previous post, it's a "BBAI".. Sep 01 19:49:56 ahh. that would explain this actually. Sep 01 19:50:10 that image you mentioned, is for the 64 Bit, BBAI64.. it won't do anything on a BBAI.. Sep 01 19:50:40 aahh. did not notice that. Sep 01 19:51:32 rcn-ee: btw, not sure how common knowledge this is, but in case it's useful; a short tutorial on how to do remote debugging of nodejs -> https://pastebin.com/skVvPRSC Sep 01 19:51:53 (using Google Chrome) Sep 01 19:52:26 Guest19: as your looking at 11.x, grab today's snapshot... https://forum.beagleboard.org/t/debian-11-x-bullseye-monthly-snapshots/31280 these last few weeks i've been cleaning up on teh BBAI again... Sep 01 19:53:36 zmatt: that's cool! i normally stay out of nodejs, but it's cool to know.. Sep 01 19:54:03 Guest19: is there a specific feature of the bbai that you are trying to utilize? Sep 01 19:54:49 zmatt: does `sudo systemctl enable --now bb-code-server` work just like disable does? Sep 01 19:54:54 yep Sep 01 19:55:05 enable --now = enable + start, disable --now = disable + stop Sep 01 19:55:37 rcn-ee: no particular features. I just want a headless server. Sep 01 19:56:10 thanks for the heads up. I wasn't aware of that page. Sep 01 19:56:18 Guest19: ah then, just grab the minimal/iot, no reason to waste the cpu cylces on xorg loading! Sep 01 19:56:42 that use-case sounds like you'd want minimal indeed Sep 01 19:57:38 and a fan to cool it ;) Sep 01 19:58:35 yes, the reason I ended up with that image was because I noticed on the download page that it was the only 11.x installer. I was going to get IOT but that one's still at 10.3 Sep 01 19:58:55 (I was going to do that and then uninstall the xfce libs) Sep 01 19:59:19 currently downloading the minimal snapshot Sep 01 19:59:21 it's easier to start with a minimal image and install just the things you need then to start with a bloated image and try to carefully remove superfluous crap Sep 01 19:59:30 i think @jkridner is going to update those pretty soon, now that everything is stablized again.. Sep 01 20:00:17 zmatt: much prefer to do it that way too Sep 01 20:00:18 rcn-ee: thanks for the update. I appreciate very much that you guys are maintaining this Sep 01 20:27:59 not sure why I keep getting disconnected, but thanks zmatt and rcn-ee: was saying I apprecaite the fact that this is all being maintained. Sep 01 20:30:22 Guest19: yep, that message came through! Sep 01 21:21:42 I do have another question: I'm not sure if my hardware is flaking out, but when I power on my BBAI, the LEDs don't 'always' come on. Prior to wiping my mmc, the beagle would power on (green LED next to USB-C) but I would have to hit reset then power to get the USR LEDs to come on. Now that I've wiped my MMC, I can't get USR LEDs to ever come on. I Sep 01 21:21:43 have the impression I must either be missing something obvious, or this is a hardware issue Sep 01 21:23:24 the USR leds not coming on just means it's not booting, it doesn't say anything about why it's not booting Sep 01 21:24:54 so "Now that I've wiped my MMC, I can't get USR LEDs to ever come on" is equivalent to "I haven't managed to boot from SD card yet" Sep 01 21:25:43 roger that. Sep 01 21:27:59 that could of course be due to a hardware issue (e.g. a defective card slot), but in that case the slot would just not work whatsoever (and not merely fail to boot from it)... it sounded to me like that isn't the case in your situation Sep 01 21:30:09 not sure what to make of the other issue you just mentioned, about previously having needed to reset to get it to boot.... while I think I've had sporadic issues with booting at some point in the past, it normally has no problem booting immediately when I apply power Sep 01 21:35:49 but my bbai is probably my least-used board, in no small part because of its tendency to overheat Sep 01 21:38:59 it might be a card reader issue, honestly. Sep 01 21:39:11 I have no positive confirmation that I ever read the SD card. only that I was able to boot to mmc. Sep 01 21:39:44 Is there anything I should know about the flashing process? I'm just dd'ing the uncompressed image to the sd card. I'm not setting it as a bootable partition used parted or anything like that. Sep 01 21:41:25 dd'ing the decompressed image to the sd card *should* work, be sure to overwrite the entire card and not a (typically the only) partition Sep 01 21:42:16 we generally recommend using https://www.balena.io/etcher/ since it's less error-prone, and additionally performs on-the-fly decompression (no need to unxz the image) and more importantly verifies the sd card contents after flashing to ensure the card isn't flaky Sep 01 21:42:54 (I have a microsd card whose contents is different each time you read it) Sep 01 21:43:15 ok, I will give that a try. I've been making sure the image is mountable every time I flash it. Sep 01 21:43:26 I'm actually going to try another SD cazrd Sep 01 21:48:04 this is unfortunate. I think I may have bricked my bb after all by virtue of having a bum sd card reader and no longer having a viable emmc os. I just tried a known good SD card and it won't boot Sep 01 21:48:57 oh, as if Murphy were watching over my shoulder. it just came up Sep 01 21:49:12 ok, matter is settled. Thank you again for taking the time. Sep 01 21:49:28 a bum sd card is unlikely since I think the board gets flashed in the factory *using* the sd card slot Sep 01 21:49:50 (though even with bum sd card it wouldn't be bricked technically, it would just be harder to recover) Sep 01 21:50:01 also, yay, my RNG microsd card still works! :D https://pastebin.com/raw/zYtDPZrD Sep 01 21:50:53 *a bum card slot I mean Sep 01 21:54:18 I think the card slot would have gotten bum from mistreatement post factory Sep 01 21:54:36 I'm very closed to convinced that's the issue now. I just swapped out the SD card to check something and it won't come back now. Sep 01 21:54:52 I believe there's a connection issue. I'll have to be gentle with it once I boot back in Sep 01 21:55:25 (mistreatement from me, that is) Sep 01 21:56:32 at work we ran into a bbb with bum sd card slot, which got discarded so I gave it to a friend... he discovered a slightly bent contact in the sd card slot and fixed it by bending it into proper position Sep 01 21:57:50 I'll give that a looksy. my eyes ain't what they used to be though  :| Sep 01 22:05:01 I wonder if cpu prcm on the am57x got fixed in newer kernels... on my bbx15 running 4.19.94-ti-r72, using my utility to enable cpu power management causes the cpu temp (while idle) to drop very substantially... https://pastebin.com/Ms2CVnDU **** ENDING LOGGING AT Fri Sep 02 02:59:56 2022
