I didn't think it belonged in Dream Android Development, so I'm putting it here. If it needs to be moved, move it.
Is it possible to boot anything other than Android on the Dream?
I've seen the Nokia N900 and its Maemo 5 firmware, and I'm absolutely drawn to it, thanks to its debian-based OS (sudo apt-get install anything), it's X-based graphics system (REAL linux GUI programs), and all the apps it already has (Native Gizmo > Hacky Sipdroid).
I've also taken a look at other Linux-based open phone firmwares.
What is keeping us from doing this? If it's drivers, do they exist for another similar Linux-based firmware?
Could we dual-boot Android and this other OS using a third-stage bootloader which loads as a kernel from within the BOOT: partition?
I've seen the (albeit extremely hackish) method of getting Debian on the G1, chrooting into a loop-mounted FS and using a loopback VNC to spring into a KDE/Gnome/LXDE UI, but it's slow, still has Android and its apps loaded into memory, and very hackish and unstable.
I'm more than willing to test anything firmware-wise on my phone as long as it doesn't mess with my SPL.
The possibilities are nearly limitless - WINE under Linux means true "Windows Mobile" without the WinCE kernel.
Or perhaps WinMo/WinCE can be booted on the Dream?
It's more of a question of whether or not it's possible right now than a concept or implementation, but once that's answered, I'll either throw some time into testing and porting, or kick back and enjoy the Android as it is.
For starters:
- How does the SPL hand off to the BOOT: partition and its kernel/initrd?
- What devices need what drivers? What should be thrown into the kernel?
- Do things need reverse-engineering or is it all straightforward and documented?
- How can we use the space provided without messing with the SPL? (use cache partition for OS? Modified recovery that doesn't depend on cache partition?)
- Is dual-booting between Android possible? Can this be switched and launched before Dalvik and the Android stuff loads on the Android kernel?
- Can this be done with other Android-powered, rooted devices?
Have you seen wiki.openmoko.org/wiki/OpenMoko_on_HTC-Dream or lists.openmoko.org/pipermail/community/2009-August/052529.html? (Crap, I can't post links) Looks promising since Angstrom is a very powerful embedded distro, but it's a one-man project now. I hope some people will join it or start a similar project.
G1 is a great device, however, I can see only a few people hacking on OS alternatives for it. You always got to have either an active community or a company in order to complete such a project.
The Android hackers community is very vibrant, however, people are not really interested in bringing a fully-featured Linux distro to G1 or other Android phones. Android is too trendy itself
The Debian/Ubuntu opportunity that we have now is nice, but it looks like an addition to the Android which takes a lot of memory and CPU.
I have just set up a small Ubuntu environment booting on my G1 together with Android. I combined the userspace prepared by Paolo Sammicheli (xdatap1.wordpress.com/2009/05/03/jaunty-under-android/) with Bayle Shanks's instructions (bayleshanks.com/wiki.pl?tips-computer-android-g1_debian_cyanogenMod). I am going to use it for mutt, vim, some coding. X11/VNC experience has been frustrating so far.
I am pretty sure though that there will be more people wanting to use alternative OSes on their phones: Moto Droid and Nexus are powerful enough for a full desktop environment.

i really think it lies in what you want from your phone... i know you say you use your ubuntu env for things such as vim and mutt, but everything that vim and mutt can do, can already be done under android..
the biggest challenge is getting people to latch on to an alternate distro which offers MORE than android, which has yet to come to surface... ultimately this is a phone.. not a netbook...and for a phone android is pretty dam sweet...
although in terms of geek work, running ANY other os on non native hardware is cool....albeit not really worth it
anybody were successful by using the internal-memory-image from the openmoko wiki?
I always get kernel panic, when booting it. I flashed it with flash_image boot/system, does this matter? In the wiki they use fastboot.
scheich, I only tried the SD-card way (see my post in http://forum.xda-developers.com/showthread.php?t=624392)
It shouldn't really matter whether you use fastboot or flash the image. The kernel panic could occur due to the inability to find the root filesystem. Try reflashing the yaffs2.
By the way, why did you choose to put OpenMoko in the internal memory? Are you going to use it exclusively or as the primary OS on the device?
Some of what you suggest can be done, but not recommended.
1) Nokia/Maemo is a bad fit for a phone. It is a real HOG. It is also shoehorning (with a sledge hammer) a desktop OS into a phone. It just doesn't work right. Android exists because a totally new UI model was needed to work optimally with a phone's physical form.
2) WINE will NEVER work since the CPU in the phone is ARM and not x86. If you want to run windonkey programs (can't imagine why you would), you would have to run a PROCESSOR EMULATOR, and this will be REALLY REALLY REALLY slow and memory intense.

Tried reflashing the system image. Also the older image on the ftpserver. The same. I will try the sdcard installation.

Two reasons:
1. Thought that would be the faster way to get it work. I used BART to backup my android installation.
2. Thougt, I would get a bit more perfomance in using the internal memory.
I really would like to use SHR(or other) as primary OS, because I had an GTA02, depends on what is(could) work(ing) on the dream.

NBR is targeted at x86, but Ubuntu MID edition is installable. It's similar to the netbook remix. We'll have to wait before we have a proven/stable installation method though.

Well, you can try the OpenMoko port (it's in the alpha stage now): http://forum.xda-developers.com/showthread.php?p=5521417
The more people get interested in the alternative OS, the sooner we'll get one.

Really hot stuff - but i don't want to loose my recovery
But i will definetly keep an eye on it!
edit: Adding a bootmngr like grub for selecting boot OS (android/openmoko/recovery) would be really nice Or adding bootoptions to the current amon_ra Recovery would be a soloution too. But I'm no dev, so I don't even know if it is possible.
So, apparently owners of the HTC Rhodium (Touch Pro 2) can dual boot OSes now. Here is the quote "Reefermattness has created a package that quickly installs the updated Android package for the GSM and CDMA Rhodium, also known as the Touch Pro 2.The package also includes the famous Gen. Y Dualboot application by Yozgatg, which makes it possible to choose your OS at startup." found here http://www.xda-developers.com/android/new-dualboot-xdandroid-package-for-gsmcdma-rhodium/
Question is, CAN THIS HELP US? I know it would be awesome to dual boot ROMs. So, can a DEV take a look and see if this can be done with the Hero as well?
I think we'd be running short on ROM space if we tried that.
Yeah, the CDMA Hero system space isn't too big. Those Touch Pro2 guys have more space to work with, as in enough to dual boot. We barley even have enough to install roms.
The android files are stored on the SD card in a dual boot scenario also. I also don't believe it's true dual boot. You have to boot into WinMo first, then run an executable that loads the Android image. The Gen. Y Dual Boot application actually loads after WinMo loads as well I believe.

You're right. True dualboot is like Boot Camp on a Mac, it loads into a bootloader BEFORE any operating system and you choose which OS you want to boot into. Booting into WinMo and then into Android isn't true dual boot.
I dont really care about TRUE dual boot. As long as you can get 2 ROMs, that would be cool
wow I'm surprised its news, back in the TP1 days we could boot into a less than functional version of android from Winmo...
Can you dual boot or any other way to have 2 different roms installed at the same time,so i can switch back and forth?Like windows either at boot or logging in and out of 2 different desktops.
Maybe find a way to split the partitions.Any suggestions would be great.
Duel= 2 roms fighting. Make it dual. Thought it was funny, no malice intended.
lol - duel - dual...
It would be interesting if that was possible. There would have to be another program in there to act as the buffer between both OS's though - that would take control of the start-up, hold on a page that has both options and then would boot the option you want.
Not sure if that's possible since some files are right on the root and in order to have an OS work it can't have files in the same directory - they would just overwrite each other.
But, I too, have wondered if it would ever happen. Be a great way to test new ROM's if you didn't always have to overwrite the existing ROM but rather, you could place a new ROM in a special directory and then run it from that - or partition the internal memory with the new partition available to boot from and store.

Thats exactly what i was thinking,partition the system os,i rebuild computers and a little system modding in windows,but this is a linux based os,so it would be a little odd for me.I'm gonna look into this a little more.
You may try to contact the guys who developed boot manager. www.init2winitapps.com they have a listing of supported devices and a request form. Works on the thunderbolt 5 slots for 5 roms, I'm unsure how difficult it would be to add support for the iconia.

Thanks,i submitted the idea,lets see if they will run with it,hopefully they will find interest.
Hello Diabblo,
Any update on that?
I think the idea of dual boot (or 5al boot) is just fantastic!
I have beside my iconia a501 a poor old zt180s and it can triple boot on android, ubuntu and WinCE!
Best,

Im guessing that device has a open non encrypted boot loader. The Iconia was encrypted at birth with the 3.2 push they tightened security even more from whqt I have read.So this is likely never happening unless acer changes ttjere boot loader policy.not likely to happen.
hope this helps you understand more of this issue.
I'm dual-booting my A500 right now with ICS and Ubuntu. The method for dual-booting is a replacement recovery.img which contains a Linux kernel and acts as a bootloader for Linux. Ubuntu itself runs from a rootfs.img on the internal storage (there's also recovery.img's available to run from external SD too). If I want to run Android, I just boot my tab normally. When I wanna run Ubuntu, I hold vol+ as I'm turning it on to force the modded recovery to load. It's a pretty cool setup more info in this thread: http://forum.xda-developers.com/showthread.php?t=1158260
Dear Erica Renee and Bloodflame,
Thanks a lot for your answers. Ok, I got it with the encrypted bootloader.
Will try the method described by Bloodflame.
Actually, since I got these tablets my main use of them is flashing new ROMs... I don't really have the use of new ROMs but I think it's so exciting!
Cheers,
Inji.
I don't believe the encryption is the problem.
The current boot loader is available unencrypted in update packages if anyone want to have a look at it.
Replacing the boot loader on the device is done as part of a down grade procedure described elsewhere on this forum.
So unless I'm missing something, the problem is more likely time and interest. Someone need to care enough about it and have the time to make some other boot loader work. Or patch Acer's. Either way it is likely to require quite a bit of time and patience.
So let me see if I have this correct. Acer's hardware bios code is 'locked down' enough to keep the average code manipulator out? A custom boot loader needs to be dev'd that can communicate correctly to be able to handle Android recovery and a linux/android boot screen etc. ? Could someone elaborate more blatantly if I am incorrect...
I was wondering if it would be possible to install linux (ubuntu) on the Nexus Player? I feel like this would be the perfect device for this.
No. Seriously. This is worthwhile. Small footprint, capable hardware. No significant hurdle.(?)How? Tutorial! Please!

Agreed. The only thing I can see possibly being a problem is getting 3D acceleration working because of the PowerVR GPU. Everything else on this device seems well suited for Linux. Would just need a boot image akin to Ubuntu Touch on the old Nexus 7. Sadly I haven't seen anything that would help get this started on the Player, and I currently don't have the experience to start it myself.
Uh, it's already running Linux. It sounds like you just want to run a different Linux distribution than Android. Shouldn't be difficult. You can run debootstrap on a clean system partition from recovery. You'll need to modify the boot image to run your distribution's init instead of trying to boot android. I would just look at the Ubuntu phone images for an idea of how they do it.

It's usually not that simple. The boot partition from the examples I've seen (Ran Ubuntu desktop on my Nexus 7 2012) has to contain the kernel for the regular Linux install. I haven't looked into how big the partition is on the Player, but I know I had issues getting a mainline kernel to fit on the 8MB of the N7 2012. Plus most of the people here (including myself) wouldn't know where to even start at trying to get this to work for the Player (Hence why we ask in a community that has the expertise to possible pull it off). Specs wise the Player could be a fairly nice cheap NUC (If the PowerVR has support, that would be even better)

You are not making sense. Usual linux distro has a boot partition that contains 1 or more kernels, and 1 or more ramdisks that match those kernels. Usual linux distro also has a multi-boot boot loader, which is able to select between the available kernels and ramdisks. An android device is arranged such that it has a SINGLE-boot bootloader, and its boot partition is just a kernel+ramdisk stuck together. You can stick a ubuntu kernel and ramdisk together in the EXACT SAME WAY, if that is what the bootloader requires.
As far as "getting a mainline kernel to fit... blah blah blah", the thing is... mainline kernel isn't any bigger than what you have. The difference with a "typical linux kernel" is that it isn't built with just the drivers that support that specific device, it is built with pretty much EVERY common driver built in, so that it will work on most hardware without being rebuilt. Delete the crap that you don't need, and it should fit just fine.
OR for that matter, what makes you think that something like Ubuntu won't work just fine with a kernel built for Android? Android runs on a LINUX KERNEL. Just change out the ramdisk for one more suitable for... whatever, and call it good.
Now the big question I would have about doing this.... is WHY? Nexus Player is awesome BECAUSE it runs Android TV. If you are looking to run a desktop linux on a thing that plugs into your TV, look into something like an INTEL COMPUTE STICK.
I've been trying different ways of entering bios and/or disabling secure boot, but can't figure out exactly if it has a BIOS menu at all.
Connected a keyboard to it and tries different keys during boot but I can't find the right combination.
Does anyone know how to enter the BIOS menu, or how do we go about disabling secure boot?
Thank you,

From my LG-G4, Rooted running Stock 5.1
I was afraid that this would be the case. There seems to be no way to circumvent it either to boot a linux kernel.

Am I right to assume that the only thing we have that are signed are the stock Lenovo Yoga kernels, making them the only thing we can boot?
Also, does anyone know if these are the Microsoft keys, or some Lenovo keys, that they use for secure-boot. http ://i.imgur.com/dm1i16B.jpg
I'm wondering, because linux grub distributions do have a signed grub "shim" with the Microsoft key, maybe making us able to execute that at boot.
Ok, I've found out that it does have the microsoft keys, among other keys, which means it should in theory be possible, in theory. Will be looking into this more.

actually the problem is not in the unlocking but in making a working kernel for this tablet... because you see... Lenovo released the "source code" so they won't risk being sued for breaking the opensource (kernel) licenses, yet what they released is crap, broken drivers (i had to download all the source packages from all the YT2 models because they didn't even un-tarred crap and each one was 400MB and move things around and still it wont do the job as it should) they intentionally crippled the mk files, removed others, stupid and not working configs and so on... driver files missing... you get the picture and this was intentionally (not to say that this is only the kernel, not a chance to see in their source whats even more interesting: the code for the libraries, binaries etc) i am not saying it cannot be done but the amount of work it requires... hmm does it justify? in the end there are few people on this tablets and even lesser with the knowledge/available time to try and do something that will look like a custom rom
i thought at some point in making a rom but the hassle and time required don't justify it (what would i have? except that it's trendy to have a costom rom) so i for one will stay on my Android+Linux combo but who want to go further has my help
a better approach would be to build a custom rom based on the stock kernel/initramfs, this way you will start having the drivers in order and do your custom system (while no longer used in these days still it was cyanogenmod's way of making custom roms in the past) yet this one too is difficult and requires lots of work (and again for what? what's the gain?) but this one is much more acceptable than the rebuilding all previous one
the secure boot is passed (pm and you will understand) but to what end? see... the problem isn't so much in opening the door but in what you will do once inside (and i am inside that room for some time now yet no better bed than my Linux+Android combo) but feel free to continue on the road..
this is not to discourage you but to warn you about issues others (me) had on the road you're stepping now.
Thank you for the reply.
You're right, going the route of compiling whatever Lenovo has put out, is not the most streight forward option, but I disagree on not putting Linux on this tablet. This is the biggest and highest resolution tablet I've seen, and having Android on it instead of a full-blown Linux distribution, is a waste. Things like X forwarding to use it as a thin clinet, does not work well, I've tried all options. The only viable thing for using this as a thin client, is to run Linux on it, with its native input methods on the display server.
The gain is not having to pay twice as much for a Microsoft Surface tablet to install linux on, with it even being lower resolution and smaller screen.
well in this area @workdowg can give you more details as he is the one who loves X on this tab me i'm more like an Y type (aka windows gui/y) (i am happy with my openvpn and sshd) but again consider the unlocking part done and start collecting stuff for making your kernel

Very exciting. Need to boot a compatible kernel with the provided drivers, as you also suggested, and eventually get a full fedora distribution up and running.
Since this is an x86 tablet, no cross-compilation will be needed so it will allow for more flexibility with getting tools into initramfs to make it bootstrap systemd, and eventually run a full distribution from the system partition.
Would be very interested if workdowg can also provide some input on the issue.

I purchased my tablet with intention of dual booting Linux and Android and eventually going with Linux alone (being x86 I thought this would be a piece of cake). Now after getting Linux running (with Android in a chroot).... My vision has changed. TTY Linux is great, I have so much I can get done when not home. Using Xsdl, X runs well enough ( I had wine installed to run a Windows app) and I don't think it would be all that much better on the framebuffer.
The problem ends up being.... (and it has been stated before).... Touch still sucks on a small screen! Android just excels at it. So for me, if someone were to develop kexecboot or such I would definitely play with it (proof of concept) but I'm positive I'd go right back to my current setup.... ssh and the Xsdl for X as needed are perfect.

i wasn't saying to not put linux on it (i have linux on mine too) i'm saying that putting ONLY linux was not worth (for my needs) the work required for (maybe i was too subtle ) i mean even if i had a full linux distro solution for my 1380 tablet i would still go for my current Android on Linux set-up that i have. yet, each has his own needs
oh boy it's getting late

Oh I see. The highest priority for me at least, is to get any linux distribution to boot.

I purchased my tablet with intention of dual booting Linux and Android and eventually going with Linux alone (being x86 I thought this would be a piece of cake). Now after getting Linux running (with Android in a chroot).... My vision has changed. TTY Linux is great, I have so much I can get done when not home. Using Xsdl, X runs well enough ( I had wine installed to run a Windows app) and I don't think it would be all that much better on the framebuffer.
The problem ends up being.... (and it has been stated before).... Touch still sucks on a small screen! Android just excels at it. So for me, if someone were to develop kexecboot or such I would definitely play with it (proof of concept) but I'm positive I'd go right back to my current setup.... ssh and the Xsdl for X as needed are perfect.

Touch will probably work better on the larger screens, I've got the 13inch one.

So I got the latest kernel from kernel.org to boot but I'm not sure why it doesn't find the initramfs, I assume it has to do with it not existing on a partition, but being built into the boot.img.

I'm trying to make it boot a live OS directly from USB, without initramfs. It's a bit difficult because I don't know how the block devices are named, maybe if anyone knows the kernel command line for booting the live linux using the custom kernel, using sdhci or normal usb.
Basically, instead of the normal LiveUSB sequence:
grub from USB -> kernel from USB -> root filesystem from USB
I want
custom kernel with android boot.img -> root file system from USB/SD card

there's something wrong with your boot.img, and from the image there not enogh info
link the boot.img you make

What's wrong is you need the root= kernel argument, and I'm not sure how the block devices are named (For example, it doesn't have /dev/block/ like on the android kernels). The initramfs isn't modified yet, it's a custom compiled kernel with the source at kernel.org.
Created a boot.img that one can add root= kernel arguments to, to test booting from other media:
https://anonfiles.com/file/177753c2344c3c64c200cdb3803236bd
It has these kernel command line arguments built into the kernel:
Code:
oops=panic panic=360 vmalloc=172M debug_locks=0 bootboost=1 vga=ask i915.modeset=0 drm.vblankoffdelay=1 selinux=0 nomodeset ro debug noinitrd
Another one with UHCI (USB2.0) driver, instead of xHCI (USB3.0), because it might not reach init sometimes otherwise when plugged in, for some reason.
https://anonfiles.com/file/d41f495d118ab1e5ccef961baeb1bcce
No command line arguments built into the kernel, all in boot.img, boot_delay= disabled
Code:
oops=panic panic=360 vmalloc=172M debug_locks=0 bootboost=1 vga=ask i915.modeset=0 drm.vblankoffdelay=1 selinux=0 nomodeset ro debug noinitrd root=/dev/mmcblk0
