Linux Kernel Booting On the iPhone

Posted by Soulskill on Sat Nov 29, 2008 08:15 AM
from the there's-no-iphone-in-team dept.
mhm was one of many readers to note that the Linux 2.6 kernel has been ported to the iPhone. "Planetbeing, one of the iPhone devteam members, has been working on porting Linux to the iPhone (along with a custom bootloader called OpeniBoot). Today they managed to boot the kernel! Video showing the boot process has been posted. Instructions and binaries are available on the project blog."

    In other news, Apple has responded by issuing an update which accidentally causes an iPhone running a Linux kernel to become inoperable. Apple apologized for this mistake, and is working on a fix.

    For all those thinking "Android," check this from the blog entry:

    If you're experienced with hacking/porting Linux and especially if you're experienced with porting Android, I'd definitely like to hear from you.

    Oh, and read some of the blog comments. Man - I thought youtube comments were stupid, but this trumps even that:

    Ok, not to sound too stupid with this question, but since the iPhone is running linux already... why not use whatever drivers are there already?

    and:

    Oh - and the obligatory iphone linux comic [geekherocomic.com]

      This isn't as stupid as it sounds (though one hopes they RTFA'd.) I recall trying to put Linux on my Nintendo DS, only to find that installing it (without using additional hardware) required... Windows. I'm not sure if that situation has changed since, but it was a major disappointment and WTF at the time.

      <sarcasm>
      What's wrong with that comment? If you recall from history, SCO stole linux to make Unix, which they time travelled back and sold to AT&T and Berkeley. Then Apple fired Steve Jobs, who put Linux in a black box and called it "NeXT". Then Apple bought him, made their own Linux, then retroactively created 6 major versions of FreeBSD as a front.

      Then Darwin created a kernel (evolution my ass!), which he published steganographically in that ridiculous "Origin of Species". Babbage was the first to discover the hidden message when he was reading the book to to figure out why his engine got such bad gas mileage (he later discovered the flaw was that the car hadn't been invented yet, and pouring gasoline into a stationary computing engine wasn't getting him anywhere. But I digress.

      Its turtles all the way down.
      </sarcasm>

      I used to be amazed at how many self-proclaimed geeks didn't know the difference between FreeBSD and Linux. How can you expect regular mortals to know what brand of unix-like subsystem Apple has running under the hood?

      I'm a little impressed when non-technical folks know that there's some sort of open source unix behind the pretty Apple curtains, even if they don't get it exactly right.

      Just like Richard Stallman says: who cares what they call it, as long as they didn't have to pay for it ;)

          Yup, this is the situation rockbox finds itself in. No currently shipping hardware can run rockbox. And few of the existing ports ever get finished before the devs apparently lose interest in old obsolete hardware and begin porting to the new shiny. The lesson to be learned from this is simple.

      Dont forget that you have to boot the correct kernel depending on what you plan to do. The choices being :

      linux_2.6.26_AnwseringMode
      linux_2.6.26_DialingMode

It was all over this obscure mailing list last night -- try to keep up! After recompiling, all you have to do is figure out the right kernel boot parameters and compile and install a user mode daemon. After that, you can choose either answering or dialing mode at will by echo'ing ANSWER or DIAL to /sys/devices/system/phone_mode. Nothing could be easier!

    That's the #1 question. Let's not forget the iPhone part of iPhone.
  • Ironically, the video of the boot process requires Flash, which Apple in their wisdom has chosen not to support. The devs surely knew this, and probably decided not to use YouTube to tweak the noses of those of us who occasionally use our iPhones to read /. (and even post!). Their motivation for doing so escapes me, however, since presumably we are their most interested target audience. Curious.

    • You know, I dislike Flash in general because I think it's bad for the Web, and I never use a portable device to access the Internet. So I'm hardly a supporter of their decision to use YouTube. That said, if they were thinking about /. (or any other big site that might link them) at all, I'd bet all they thought is that they didn't want tons of people trying to download video off of their server at once, even on what's probably a pretty low-traffic Saturday.
