**** BEGIN LOGGING AT Tue Dec 27 02:59:56 2022 Dec 27 03:08:25 Cheer? Dec 27 03:08:41 BBB? Dec 27 03:09:08 I am trying to help this fellow but I think he understands more of what he is doing compared to me knowing more of what he is doing. Dec 27 03:10:00 So, w/ respect to him and his needs, I am going to build what he has done and try some quick research on his builds to perform pcm_* for ALSA sound cards. Dec 27 03:10:15 Does that make sense? Dec 27 03:10:32 This has to do w/ the BBB and devm and snd primarily. Dec 27 03:10:59 I know it is probably too late now. So, I will just blurt here... Dec 27 03:11:38 I tried w/ modprobe pcm_5102a and some other ways to handle it. Dec 27 03:12:03 It is like devm has taken over the kernel source but not all or something... Dec 27 03:12:36 I cannot describe it correctly as usual. So, I just wanted to mention it in case someone was building w/ this in mind. Dec 27 03:16:07 All I know...is a thing can get complicated. IF not complicated, I can keep trying. I do not hesitate to know when to bow out. So, if things get iffy on my workings, I will admit it and let this fellow know. But... Dec 27 03:16:13 Not Now...Too much fun! Dec 27 04:51:11 Good daym everyone. Dec 27 04:51:29 How quick can a beaglebone black be made to boot? Dec 27 04:52:44 Also is it possible to make some sort of a boot splashscreen while it's booting? Dec 27 05:22:11 a few seconds Dec 27 08:47:44 May I know the dimension of heatsink, guys? Dec 27 08:48:38 I uses BBAI-64 Dec 27 12:49:12 Hello and good morning. I hope everyone is doing okay. Just okay! Outside of good, ole jokes, I am building an image to help this fellow on the forums. I am getting closer to the cure (cure). Dec 27 12:49:47 It seems that there are some hidden elements not quite apparent as of now. Dec 27 12:50:36 Is EDMA a need for a .dts file under pcm_* ? Dec 27 12:52:02 The reason I am asking is b/c the fellow "should" be using the Arago Project /bin/ toolchain but he has not told me just yet if he is using this toolchain. Dec 27 18:45:45 Good day, everyone. I lost connection after asking a question last night Dec 27 18:45:53 Never got to explore the answer Dec 27 18:46:15 I was wondering how short of a boot up a beaglebone can be made? Dec 27 18:46:40 milliseconds? Dec 27 18:47:03 I mean from powerup to cli login prompt Dec 27 18:47:08 yes Dec 27 18:47:38 Right now any debian images, even console and and headless take about 15 to 30 seconds to get up and running Dec 27 18:47:56 that's a standard boot Dec 27 18:47:56 I currently have an ESP32 running a project with an lcd display and gui. The ESP loads the program in under a second and it's good to be interfaced with Dec 27 18:48:23 But that's because it's bare metal running compiled C code Dec 27 18:48:30 so it's going to be instant Dec 27 18:48:52 Is it possible to achieve the same times on beaglebone? Dec 27 18:49:03 running a small python program Dec 27 18:51:34 yes, it is possible Dec 27 18:51:52 it is just not easy Dec 27 18:52:55 I'm putting together a handheld text based game and I'm concerned about boot times. Dec 27 18:53:09 TheConceptBoy: I've achieved about 5 seconds without too much effort in the past Dec 27 18:53:43 Did you follow some sort of an instruct able? or was it trial and error mainly? Dec 27 18:54:26 I wouldn't describe it as either of those, I just investigated what was taking time Dec 27 18:54:56 disabled unnecessary services Dec 27 18:55:17 disable the use of initramfs Dec 27 18:55:56 disable cape-universal to reduce the amount of time udev spent on unused devices Dec 27 18:57:11 rebuilding the kernel with less unused stuff compiled into the kernel also helps, to reduce the amount of data uboot needs to load into ram at boot Dec 27 18:57:35 rebuild uboot to disable the 3 second delay Dec 27 18:57:53 (this is where you reach the point of shaving off the last few seconds you can) Dec 27 18:58:18 I see Dec 27 18:58:29 so this will involve rebuilding uboot with modifications Dec 27 18:59:18 once you reach the point where that sounds like a worthwhile thing to do to shave a few seconds off the boot yes Dec 27 19:06:04 (or if you want to be lazy feel free to use our u-boot build: https://drive.google.com/file/d/1Ly-DOsLy-Lij5loCfm1cukU1e2bBfjXS/view but beware that it doesn't support overlays, cape-universal, or booting from SD card) Dec 27 19:17:54 disabling unnecessary startup services probably makes the biggest impact Dec 27 19:18:18 a useful tool for that is making a boot plot using: systemd-analyze plot >boot.svg Dec 28 01:29:55 boot plot! Dec 28 01:30:21 Did I hear about someone plotting a boot? Dec 28 01:32:02 Okay...I will shuffle to my nearest corner. Forget me...I am on hiatus! Dec 28 02:09:22 Aw! **** ENDING LOGGING AT Wed Dec 28 02:59:56 2022
