How to Build Root on Raspberry Pi - Boots in 5 seconds!!!

[@cernejr]

I learned something - thank you. Buildroot definitely has real-world potential.

[@itsmith32]

Quite interesting. I was riding subway and saw black screen beneath the doors off the train with "buildroot." I thought: hmmm, Let's duck-duck... Now I've arrived and know a bit about what it is. Thank you!

[@HotMicSystems]

Damn! I found your channel years ago and forgot to subscribe and I haven't seen you in awhile, I'm glad I just found you!

[@ScottPlude]

I love it! Every time I watch another video from you, that is my new favorite. I have some pretty bold ideas for automotive tinkering. The std boot time has always been a limit but this opens up a whole new world! thanks!

[@NovaspiritTech]

Wait till you search for this "raspberry pi 3 boot 1.75 seconds", this will boot into gui too. I'm also a big car guy myself. Built my first carpc in 2006

[@steven1000000000]

@@NovaspiritTech Wow, I defintely need to look into this as well.

[@steven1000000000]

This is exactly what I was thinking regarding the automotive options - a 1 minute boot time limits some of the practical possibilities.

[@llortaton2834]

Yo don you are always on POINT PROPS!!!! i have a list of things i wanna learn about and the videos you release keep striking off the things one by one! Incredible i'm about to build my own midi controller from internet knowledge, awesome videos keep it up!

[@siriokds]

You can even remove initial logo, delay serial initialization and other tricks to speedup boot process.

[@Ryukachoo]

Possible use case; rPi dash for car projects? For situations like that you really need under 6 seconds boot

[@nathanchalecki4842]

Exactly what I am thinking- unfortunately the learning curve is too steep for someone like me hahaha

[@reyanshkhobragade5822]

That looks really cool, great video after all!

[@mikehensley78]

yes it got me thinking about how i could use buildroot. my pi0w running my ADS-B "radar" might benefit from building a system that has only what it needs and nothing more. pretty cool.

[@NovaspiritTech]

that would be really cool, not sure if they provide the source codes so you can compile

You have TURBO net speed🔥🔥🔥🔥. As always you are come with Amazing topics.

[@Nalanaij]

Very interesting. I installed arch on a RPi4 and Banana Pi Zero M2. Really like the lack of unnecessary packages and got down to 12s boot time. Now I'm working on an yocto project image for both to further decrease power consumption and boot time

[@foobarbarfoo2377]

Nice. Note that buildroot also allows to auto-expand the persistent rootfs on the first boot to fill the storage device to its physical capacity

[@MauriceF13]

Hey😊 first: awesome tutorial! second: I did the tutorial for pi3 and pi0w, but the screen (hdmi) stays off. So not turned on, it stays completely off. What do I at least have to enable to see the login on the hdmi-display? thanks man

[@pikachuchujelly7628]

Buildroot is so useful for projects that don't require a full blown desktop OS like Raspbian. The boot times and memory savings are unreal!

[@gurujr9904]

what is the difference between the lite version of raspberry pi 4 - 64bit OS, and root (as above) ....... if they are the same we can as well go directly to Imager and build it with one click isnt it ?

[@KristovMars]

Thanks for this! My project* needs a fast boot so Build Root sounds like the ticket. *Basically an "instant on" WP or text editor.

[@protonspeed]

Hey, hope you are doing well. I was trying to build a buildroot to simply stream a USB camera on HDMI. I have one error that I'm stuck to. /dev/video0 no such file or directory. Either I use vlc to capture, gstreamer , ffmpeg everywhere. I'm making this on my windows using wsl. Can you help me with this? Please 😊

[@harrytrueman4216]

Do you have any experience in installing a kanban board on pi?

[@GeorgeKGrace]

Great video! This is exactly what I was looking for. Here's what I need: 1st - I need the most minimal possible configuration (OS) to be able to boot directly into a program upon booting up on a Raspberry Pi Zero W2, with no fancy start up logo or anything (or maybe a logo of the program I'm using created in ASCII characters? That would be cool). 2nd - Being able to specify the screen resolution, is this possible? (I'm planning on using a 1280 x 400 display because that's what the program would use up on a full screen). 3rd - To be able to fetch packages from the command line if necessary for updating and upgrading purposes (all I'm familiar with is using "sudo apt update / upgrade / search / install" to be able to search and install programs from a repository, I'm not even sure what all this process is called, or if it's dependent on a specific OS (Debian?) but I'd like the same experience if possible. I assume that if I wanted to achieve the above, I can compile an extremely light version of Linux using Buildroot, but I'm not sure what to select or not. Wouldn't I need the Raspberry Pi Zero's Wi-fi to be activated to be able to fetch the packages and updates? What to select then? Obviously, I would a terminal to type into, maybe a text editor to edit the config file of the program in question, but how about any dependencies related to the program I need to run (I know for sure it needs ncurses). Wouldn't I be able to build upon the initial settings if I can fetch and download the packages/dependencies once I'm "connected" to the repositories? This is all speculation, but that's why I'm reaching out. I want specifically to be able to run NetHack on text mode upon booting up on a Raspberry Pi Zero W2 in the fastest and most simple possible way. Do you think you (or anybody) can guide me in the right direction? Thank you.

[@EcceBestia]

Ooh! I can see lots of potential for this in vm or docker container environments. Is there any way to remove the R-Pi logos or replace them?

[@mradaChris]

I gave up a long time ago to get the boot up times for raspberry pi 3 to go faster. 5 seconds is much better than what I've seen in the past. But I still think it takes too long to boot up.

[@pikachuchujelly7628]

A lot of that is due to initializing drivers. You can cut out drivers for hardware (like ethernet or Bluetooth) that you're not using in the kernel config to make it boot even faster.

[@stephenreaves3205]

This sounds a lot like Gentoo. I'm pretty excited

[@davocc2405]

Would this produce a less cluttered OS build that would potentially see the targeted apps run faster (less CPU contention, etc.)?

[@Pupek497]

How can I connect with ssh to the raspberry when I connect it to my computer with a lan cable?

[@shaharil8560]

Hi..It is a very interesting video…may I know, the 5s is starting from power supply of RPi is switched ON or from text displayed on terminal? I have tried the steps for RPi 4 8Gb..but I still cannot get the boot time less than 15s...😀

thats a nice video. i was looking for some method to customize my raspi images so i dont have to do the same basic setup over and over again.

[@cornjulio4033]

Thank you very much ! I wanted to understand how to do this for years. Dou you think it would be possible to compose a buildroot, and still make it boot over USB (SSD) ? It's possible with a normal Raspbian.

[@NovaspiritTech]

Yes

[@mauisam1]

You said something that really peaked my interest... That this the Build Root could be used as a wireless access point. WiFi is not very good and the ends of my house. I have tried extenders but they have a second WiFi name and when family comes to visit it is always confusing which WiFi to select. My house looks kinda like |____ , in which the internet and (my office) is in the left bottom corner. But the other ends of the house have very bad WiFi signals to them. I looked in to many solutions but being frugal person that I am I was not thrilled at there price. It sounds like you could use a Raspberry PI-W as an access point. Could you do a video where you connect three (or more) of them as access points? If the Zero can be used as an access point it would be a very low cost solution that could be in every room of the house. Thanks for your hard work.

[@NovaspiritTech]

i'm actually working on a video for using ESP12 as mesh networks to expand the converge of wifi around my house. that is a much cheaper solution and covers more area.

[@mauisam1]

@@NovaspiritTech Can't wait for that video! It will be interesting to see if the ESP12 can handle the high speed network traffic, as in streaming 4k video. Thanks again.

[@BartekSzzz]

Hello Novaspirit Tech! What about TinyCore disto? It's also small and fast, maybe you would show off this basic distro with Internet browser only? Some kind of Kiosk/Thin Client build on RPI, what do you think?

[@pikachuchujelly7628]

Tiny Core boots lightning fast and is great for a kiosk scenario, though the packages are a bit lacking, and you have to install the WiFi packages manually, which can be a pain.

[@seerampraveenkalyan5446]

Please answer my question cause I am the one who uses raspberry Pi 4 as a desktop and I have totally coustomised my Pi by watching your videos please help me with the question.

How does sd card speed affect the time? Or is it so small it is all read to RAM once?

[@NovaspiritTech]

the sd card speeds does effect it veery slightly, when using a class 10 i was getting about 6~7 second boot vs using uhd 1 was getting the speeds you see, about 5 seconds

Thanks for the answer and effort you put into your videos.

does that system log anything, if not no wear on the sd card, if it does like most linux systems then maybe add a ram drive/usb drive and log to that.
