**** BEGIN LOGGING AT Wed Feb 02 02:59:56 2022 Feb 02 10:48:25 Hi guys! quick question. Booting a BBBlack with a touch screen connected to it i see the Linux logo on the top left corner. I really like it, but we are trying to deliver this as a commercial product to a customer and we would like to substitute the Linux logo with out company logo. Where to i need to touch to modify this? Feb 02 16:02:40 I need to make an external power button in the BB-AI. in the BBBlack i was connecting a push button to P9.9 and GND. This does not seem to work in BB-AI. Is there an equivalent ? Feb 02 16:05:19 nmingotti: regarding your earlier question: I don't exclude the possibility it can be disabled using kernel parameters, or otherwise you can definitely get rid of it using kernel config. iirc we actually just disabled support for graphical console entirely, so it screen remains blank until the gui application starts Feb 02 16:06:44 hi zmatt, in BB-AI i don't see the logo. If i am amble to solve the last question i will run with BB-AI so my previous question becomes not so important Feb 02 16:07:53 pulling P9.09 to ground is still equivalent to pushing the power button... so if it doesn't have the desired functionality, that's probably a software configuration or driver issue Feb 02 16:08:53 P9.09 -- GND. works to shut down the BB-AI Feb 02 16:09:48 but, not to turn it on, one led turns one for about 2 seconds then it all shuts down Feb 02 16:10:06 uhh, that sounds bad Feb 02 16:11:24 so it's turning on the bbai just fine, but something is going horribly wrong during the power-on sequence Feb 02 16:12:44 this is quite a serious issue, are you able to replicate it on your machine ? Feb 02 16:13:45 I'd need to dust off my bbai, and probably flash something more recent onto it... I think it's still running whatever it came shipped with Feb 02 16:14:51 I guess I can just try with whatever is on it right now Feb 02 16:15:11 better than nothing ;) Feb 02 16:15:28 to me also pressing the power button gives the same outcome Feb 02 16:17:05 P9.09 and the power button connect to the same net Feb 02 16:17:57 ok Feb 02 16:19:29 i disconnected all my electronics from the BB-AI and tested again => still does not boot => it is on the machine Feb 02 16:20:25 it seems this system doesn't recognize the power button (short-press) as a powerdown event, but that's probably just because it's an ancient system (debian stretch, kernel 4.14.108-ti-r113) or maybe I messed up some configuration Feb 02 16:20:40 but after perform a software powerdown, I can turn it back on using the power button just fine Feb 02 16:20:44 *performing Feb 02 16:21:10 i see, in your older system you see the opposite of my problem Feb 02 16:21:59 I guess, though software ignoring a powerdown request seems much more benign than the system failing to power on Feb 02 16:22:19 my config is : Linux BB-AI-1 4.19.94-ti-r70 --- BeagleBoard.org Debian Buster IoT Image 2021-10-01 Feb 02 16:23:39 ok, I just checked with evtest: the power button is generating a KEY_POWER event, so it's just a system configuration issue Feb 02 16:24:37 ew, is that an uppercase hostname? :P Feb 02 16:24:53 no wonder the system refuses to power on sometimes ;-) Feb 02 16:25:58 dah, i configured during the winter holiday ;) let me change it Feb 02 16:27:13 just to confirm, you're pressing the power button briefly, not holding it down? Feb 02 16:28:00 just retried, i quick touch to the power button doesn't to it Feb 02 16:29:30 oh, turns out default long-press time is 12 seconds anyway (configurable 6-12 seconds in 2s steps) so it's not something you'd trigger by accident Feb 02 16:30:26 let me try it: 12 seconds should turn it on Feb 02 16:30:41 no. long press turns it off unconditionally Feb 02 16:35:17 wait wait, another minut Feb 02 16:37:05 2 seconds is a weird amount of time too, I think by then it's already well into u-boot Feb 02 16:37:24 but I'm not 100% sure about that Feb 02 16:39:50 mine is a lot more strange, i am trying to get the rule Feb 02 16:41:17 now that I think of it, I vaguely recall having had issues powering it back on when it had overheated, but it's been a long time so I don't know if I'm remembering correctly Feb 02 16:43:07 nono, it can't be overheating i have a fan Feb 02 16:43:20 to reboot mine the rule is this Feb 02 16:43:39 1. push power Feb 02 16:43:47 1. light turns green Feb 02 16:44:04 fater 7 seconds lights goes down Feb 02 16:44:11 wait till 15 seconds Feb 02 16:44:17 release the power button Feb 02 16:44:21 now it boots Feb 02 16:45:37 wait, you're holding it this entire time? don't do that Feb 02 16:46:32 although, if long-press fixes the problem then that suggest that the system (u-boot or kernel) has performed some kind of pmic configuration that causes subsequent boot to fail Feb 02 16:47:04 yes, i need to keep it down 15 seconds Feb 02 16:47:13 if i release before that boot fails Feb 02 16:47:19 and the long-press probably resets things back to defaults Feb 02 16:47:41 i see Feb 02 16:48:23 presumably my old system does not perform this same configuration Feb 02 16:48:34 this still seems weird though, if this is true it ought to have been noticed sooner Feb 02 16:49:24 yes, maybe they just unplug the beast to turn it off ;P Feb 02 16:51:08 do you have any idea if we can try to fix this ourself, i don't know where to toggle honestly Feb 02 16:54:32 no idea, but this sounds like it does need to be diagnosed and fixed. but I gotto go right now Feb 02 16:55:40 k , see u later if u r back ! Feb 02 16:59:27 * jkridner added "asking smart questions" to https://forum.beagleboard.org/faq Feb 02 17:24:35 I like that article about smart-questions... I think is important Feb 02 21:25:26 zmatt are you there ? Feb 02 21:28:21 what do you reccomend for the power button problem ? Should i write to the forum ? Mail anybody ? it is a very important thing to fix, for me for sure, i think also for other people trying the BB-AI Feb 03 02:55:32 BONE-BUSES lives! **** ENDING LOGGING AT Thu Feb 03 02:59:56 2022
