Raspberry Pi 4 8GB & USB Boot

[Music] welcome to another video from explaining computers calm this time we're going to be looking at this the new 8 gigabyte whoo raspy pi/4 and if this were not exciting enough were also going to check out when new raspberry pi o s as well as the firmware update but allows a Raspberry Pi for to boot from a USB Drive right here we have our Raspberry Pi for 8 gigabyte model so let's get inside bring in a Stanley of a knife and just cut through and glued down there they're wider raspberry PI's not have resealable boxes like every other singable computer anyway there we always finally got in oh look there's the Raspberry Pi for 8 gigabyte always nice to have a new PI so let's put this down next to its other Raspberry Pi for the rozzers and there we are so here we've now got the 2 gigabyte raspy pi/4 which cost us $35 or 34 pounds the 4 gigabyte must be pi/4 which cost $55 54 pounds and the new 8 gigabyte raspberry pi for which cost $75 or 74 pounds and the was a one gigabyte two Raspberry Pi for when the board first came out but this was removed from the consumer facing range in February 2020 when the two gigabyte model was reduced in price to a $35 now these boards are pretty much identical saved the difference in the ddr4 ram chip which is located next to the system on a chip the the RAM chip is a chip here and on the 2 gigabyte model this chip is labeled 9 LD 77 d 9 w 8 said whereas on the 4 gigabyte model if you can just about make it out here on my board its labeled D 9 w hv and on a new a gigabyte model it's labeled d 9 said CL so that's the way you can tell the difference between these boards for the 8 gigabyte model they've also made a few changes to the power supply arrangements because it has to have slightly higher current Peaks to run this 8 gigabyte ram chip and what they've done is to take some components from behind the USB - sockets and they put these new components in next to one of the micro HDMI ports oh and if you're wondering the compatibility issue that prevented the first PI for some using some USB C power supplies was fixed when version 1.2 of the board was released in February 2020 and it doesn't affect the newer 8 gigabyte model just for fun I thought we'd also take this board and compare it to the very first Raspberry Pi 1 model B from a 2012 so if we take this and we put it down here like this we can see the massive changes in piedumb which have taken place over the last eight years not least we've moved from a 32-bit single core 700 megahertz processor to a 64-bit quad-core 1.5 gigahertz processor and we've gone from means there were 256 or 512 megabytes of RAM to 8 gigabytes of RAM we've gone from a 2 USB 2 port to a 2 USB 2 and 2 USB 3 ports we've gone from a 26 to 40 GPIO pins we've gone from 1 to 2 HDMI ports or omitted lis these have shrunk but somewhere along the way we've lost the RCA composite video connector which I always found rather reassuring right I've now connected up alright gigabyte raspberry pi 4 and I'm also going to pop this a timer only fan shim on to the end like that - a very quickly give us some rather effective active cooling and I've also inserted a micro SD card into the the PI for a gigabyte onto which I've written the May 20 2008 i OS which is the latest operating system for the PI from the Raspberry Pi foundation so if I now turn on the power our board will boot up and if I use the magic of filmmaking to pause the splash screen we can see that we are welcome to the Raspberry Pi desktop powered by Raspberry Pi os 32-bit which is in effect the latest version of raspbian but with a new name and as I hope this makes clear and to some reports online raspberry pi OS is not a 64-bit version of raspbian however as a 32-bit operating system cannot address more than 4 gigabytes of RAM rasberry pi OS does contain some workarounds to allow the use of 8 gigabytes of RAM on the latest PI 4 and if we go here to accessories and to task manager we can see which is the case there we are let's just drag it out I've scaled my fonts as usual but you can see here we've got just under 8 gigabytes of RAM freely available a little bit were being used to the GPU things like that so it really is amazing isn't it we've got 8 gigabytes of RAM available to us here on a Raspberry Pi and to make absolutely clear what's going on because there is some confusion around let's launch a browser and to take a look at the blog post which announced a pie for 8 gigabyte model and if we scroll down a bit here we get to this section where the first paragraph opens with three very important lines which makes it clear that the default operating system image uses a 32-bit LP ae kernel and the 32-bit userland and this allows multiple processes to share all they gigabytes of memory on a 32-bit system subject to the restriction of no single process can use more than three gigabytes and in this context it's well worth noting that every tab you're opening chromium in the chromium browser is a separate process and we look a bit further down here you'll see that they've actually launched a beta of a 64-bit version of a raspberry pi OS which is based on the ARM version of Debian 64-bit with a a raspy pine desktop and just to be absolutely clear it says it explicitly here rusty PI OS is the name for both the 32-bit and 64-bit versions of a latest operating system and the Raspberry Pi foundation and indeed we can see that if we look at our downloads here click on downloads there and go to there we are Bradley PI OS previously called er raspbian and if we scroll down you'll see so two two-bit 32-bit 32-bit although there is that 64-bit beta which are we looking at on which I am at some point in the future and if you want to know what I think about all this you can always go to the community tab on the explaining computers a YouTube channel which is a sitting over here and if you look down are there you'll see we've been having a long chat about this all about what's going on with raspbian and raspberry pie West all that type of stuff always make sure you check out their community tab on the explaining computers channel and a talking of YouTube I'm sure you want to know what video playback is like here on the Raspberry Pi OSS just to bring up there for my sample 1080p clip there it is this let it come to life and there we are will bring up a stats for nerds this is playing a 1080p and it's doing it pretty well I'm unimpressed with the playback all that 1080p footage here in raspberry pi RS I know they said raspbian there but no it's a raspy point OS that there are some dropped frames as we can see up the top it's not absolutely perfect but at 1080p playback in raspberry pi OS is in my view perfectly acceptable and a 720p playback is it very very good indeed and we should note we're not just talking here about the 8 gigabyte version of the arras peopie running a rat beep iOS because if we transition to the 2 gigabyte PI for running Raspberry Pi OS here we are we're on the 2 gigabyte board here now if we again play exactly the same clip at set it off and a full screen you will see that playback is pretty much identical it'll get to full screen eventually please do it now we are will bring up but stats for nerds and again we have got some dropped frames we seem to get more things to start off as you can see here but as time goes on things that improved but this is playing our HD for teacher pretty well as well so it does seem but in a Raspberry Pi os browser-based playback of a streaming media is it is pretty good certain even it much better when it was you know not long ago when the Raspberry Pi for was a first launch so this is all pretty good now other than the fact we can play media better than we used to be and we've got access to 8 gigabytes of RAM which of pretty good things there's not that much which is different in the rice with POS compared to the previous version of it raspberry a few things for example vo - the volume control here and white click we can see that HDMI and the AV jack the a 3.5 millimeter audio output are now treated as a different Elsa or advanced thatx and architecture audio devices and the other thing it's different if we look at the menu where the sames of the programs are here as we have previously evident a great deal of change here that didn't need to be able to it was pretty good no point in changing things for the sake of it but if we look into help you'll see we got this thing called bookshelf which is a rather exciting and this gives access to free copies of many of the magazines in the books published by Russ B Point press which includes a magpie magazine lots of really good books on coding stuff like that which is fantastic to see here you can click on these download a PDF the hack space magazine the wireframe magazine and the most important thing here of course is if we go to an issue 83 of a mag pilot open that up that there and we go down to page 84 as you can see there was a an interview with me which i think is very exciting as it's the first time I'd be directly featured in an operating system right for my next trick I've got our two gigabyte razz be pi/4 hooked up to the Blackmagic Design video assist 4k here as its monitor and as you can see we've got a Raspberry Pi os on the display and what I'm going to do is to shut it down like this and that we're at the PI for now shutdown we'll see some little flickering of it LED down here that will eventually finish but it's fully shut down there we are I can now turn off the power like that and what I'm now going to do is to turn over the Raspberry Pi 4 so I can remove its micro SD card on which Raspberry Pi OS is installed so I'll get rid of that and down here I've got a Corsair Voyager Vega 16 gigabyte USB 3 Drive which would have plug into the the Raspberry Pi for like that and so I'm now going to power on again there we are the Pius now powered up and hopefully if we cross our fingers that PI 4 is going to boot up from the USB Drive it seems to be doing things there whereas peat on the screen there were a good indication all we had the splash screen there for a Raspberry Pi OS I did prefer it when the operating systems had things on the screen when they were booting rather than all this blackness I'd like to see some text there but we don't get it these days but hopefully in a second we will arrive there we are in a Raspberry Pi OS which is booted from that this a USB Drive it's almost magical isn't it we've been waiting with this to happen on the Raspberry Pi for for a very long time and whilst here we booted from a USB Drive we could just as easily booted from something like this an SSD with a SATA to USB 3 adapter and to make this work what I've done is I've applied a beta firmware update to this pi 4 and in the next section of the video I'll show you the process I used as we do the same thing to our new a gigabyte Raspberry Pi 4 model however before I do this it's very important to note that installing beta firmware on your PI is potentially a very risky thing to do which may seriously damage the board and leave it on a table so if in any doubt I would advise waiting for the official rollout of USB boot functionality rather than implementing what I'm about to cover in the next section write all cautions noted here we are back in Raspberry Pi OS on our a gigabyte whereas before and I've opened up the terminal where I've already executed a sudo apt update and a sudo at full upgrade to ensure Raspberry Pi OS is fully up-to-date and that we have access to release his firmware updates and to check this if we open up a file manager there we are and if we go to a root filesystem and the libraries and the firmware and somewhere down here there should be a Asprey pi if I can scroll down there we are Raspberry Pi the bootloader and that we can see here the latest stable firmware update is from what the 16th of April but the latest beta update is here from the 3rd of June and that's the file I'm going to install but if you find a later file here obviously you should use the latest file so we go back to the terminal we're going to execute this command VC Gen CMD bootloader version to show us their current bootloader version which is the 16th of April version we just saw in the stable releases but we want to install the latest beta so what I'm going to do is to do a sudo our PI D prom update minus D minus F are the flags and then we need to give it a file name of location we were just at which is that so we'll just make sure we checked it very carefully I have an out execute that there we are and it tells us the update his of pending so all we need to do now is a pseudo under reboot there we are we've come up again which is a great relief weekly haven't broken things that entirely and if we open up the terminal like that and we find again our VCC mg bootloader version we can see yes we're now running the the June 3rd 2020 bootloader version so we should be able doubt to USB but so the next thing we need to do is to actually try this out so we're going to take these Kingston SSD and plug it into the pie and there we are we'll just cancel whatever's currently there on the drive and what I'm going to do is to go to accessories and a SD card copier and we're going to copy Raspberry Pi OS from the SD card on the system which is there to this kingston SSD which is there so for now click on that start so the raise everything on the kingston drive yes that is correct and this little copy raspberry west to that SSD from which we should then be able to boot and there we are it's finished and if we wish to here we could simply reboot the PI and it would reboot from the SSD because the boot order is USB first and then micro SD card but I'm going to do this in a more exciting dramatic way I'm going to close down the PI and then I'll remove the micro SD card so I've gotta then get it out it's stuck there we are micro SD card has been removed from the pipe the only drive connected is Thea SSD so we now turn it on again and yes here we are back in Raspberry Pi OS but this time running from our SSD connected via USB 3 and in fact if I go to the terminal and maybe do an LS yeah okay like that this block devices you can see very clearly here that we are running from the 128 gigabyte SSD this is very good news indeed so there we are we've entered a whole new era of a raspberry pi 4 PI them with the ability to boot from USB to boot from if we wish an S d and I think this is probably even more significant that launch of this particular new board with 8 gigabytes of vram because well it's nice have a bigger bite of Ramallah Raspberry Pi that the vast majority of applications of Pi is useful you don't need 8 gigabytes of RAM and yet the ability to boot from an SSD a faster more reliable Drive that's a really big development for the world of Pi them particularly if you want to use a PI for example as a small desktop PC and we also shouldn't forget the big price difference between this a gigabyte Raspberry Pi 4 for $75 and for example this Raspberry Pi forward 2 gigabyte model for $35 you can actually buy this 2 gigabyte has to be PI 4 and this satyr to USB adapter and this kingston 128 gigabyte SSD for less than the price of this 8 gigabyte RasPi pi/4 which makes you think doesn't it we've now got lots of options in the world of Pi we need to think very carefully about which boards we buy which accessories we buy for any particular application the 28th of June 2019 the Raspberry Pi 4 was released and it was a secret launch but I was lucky enough to be supplied by the board in advance by the Raspberry Pi foundation so I could post a video about the Raspberry Pi 4 on the day of release and I remember it being a very exciting day a year later and the Raspberry Pi for continues to evolve into a more and more capable single board computer but what are you doing or what do you want to do with a Raspberry Pi fall please let us all know down in the comments section but now that's it for another video if you enjoy what you see no please bastard like button if you haven't subscribed please subscribe and I hope to talk to you again very soon [Music] you
