Hey Has anyone gotten ubuntu 11.04 to run on boards with less than 512M ram? I have a laptop drive connected over usb that I could put a swap partition on. -- Brad Midgley |

Which run level of Ubuntu? I have been running 11.04 Desktop on Overo Tide with 512 MB RAM and I do not see any reason why I cannot run Ubuntu on run level 1 on other Overo boards with lesser RAM. Ubunu is just a OS (root file system, apps, drivers and gui which is optional depends on the OS run level). I think LXDE (light weight x11) that runs on GDM may make Overo more responsive than if Ubuntu with Unity desktop UI.

Yes. I can definitely run Ubuntu on 256M but full gnome is a little clunky---LXDE is a more usable window manager in this case. Equally, if you are just looking for a gnome look and feel, I'd recommend Steve's images (http://www.sakoman.com/category/7-gnome-daily-builds-r12.html) as they are rather lighter on their feet than a rootstock generated Ubuntu. Likewise, Linaro ( http://wiki.gumstix.org/index.php?title=Linaro ) has a good range of Ubuntu-based images for different device capabilities. -Ash On Wed, Jun 8, 2011 at 3:22 AM, AKS <aun...@gm...> wrote: > Which run level of Ubuntu?

ash, what kind of rootstock magic do you use for overo? is it in the wiki or can you share here? On Wed, Jun 8, 2011 at 9:19 AM, Ash Charles <ash...@gm...> wrote: > Yes.

Have a look at: http://wiki.gumstix.org/index.php?title=Installing_Ubuntu_10.04_on_Gumstix_Overo (to be honest though, I can't think of a case where either Steve's images or the Linaro images aren't a better choice than stock Ubuntu mostly because the kernels in both cases are specifically configured for the Overo. This may change as the Linaro fixes flow back across to Ubuntu) Ash On Wed, Jun 8, 2011 at 9:27 AM, Brad Midgley <bmi...@gm...> wrote: > > Brad Midgley |

Folks, The title of the thread is funny now that I see I have 512MB on this board :) So I used linaro to make the desktop image, following suggestions (thanks Brad P). I got the latest snapshot images of "11.05" whatever that means. linaro-media-create --rootfs ext3 --mmc /dev/sdb --binary linaro-n-xx.tar.gz --hwpack hwpack-xx.tar.gz --swap_file 256 --dev overo However, while the resulting image boots up great, usb host is not working. From the console I see lsusb only shows the built-in hubs even though there is a hub connected to the tobi host port and keyboard/mouse plugged into that. I'm not doing anything with the otg connector. root@linaro:~# lsusb Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub hciconfig shows no adapters, that seems fine... but I also can't hciattach bluetooth root@linaro:~# hciattach ttyS1 csr 115200 noflow Can't get port settings: Input/output error Can't initialize device: Input/output error this is an overo fire with bluetooth pcm wired to the cpu. current tobi attached and lan works great.

I'm so close to having linaro work for me... argh. So... on further testing I can see we get normal serial using a gumstix image but not from linaro. Is there something obvious they've missed in their build? I showed the loaded modules that are different below and after that the list of built-in items the working kernel has built-in that linaro didn't build in. Which module covers uart support? fwiw, usb host does not work for me in the stable gumstix image either. I only reflashed kernel and root, not uboot or mlo, but I suspect that doesn't matter. root@linaro:~# uname -a Linux linaro 2.6.38-1003-linaro-omap #4~ppa5-Ubuntu SMP PREEMPT Wed May 25 14:44:32 UTC

Hi Brad, I tried both bluetooth and USB host on a recent Linaro build and found both of the working. Bluetooth: -- as of 2.6.36, OMAP serial ports appear on ttyOx not ttySx so I suspect this is where the bluetooth and serial confusion was coming from. I did a 'hciattach /dev/ttyO1 csr' and some initialization happened. Then I did a hcitool scan and saw the bluetooth device on my laptop. I'm definitely a bluetooth newbie so you likely know much more what to do to actually test things after this point). USB Host: --- I tried hotplugging a USB device directly into the USB host port and it didn't enumerate correctly and all subsequent insertions failed. Next, I tried booting with a powered USB hub attached to the host and was able to do an lsusb to see the attached devices with no problem. I'd be interested to know exactly what cases are failing for you as this could be submitted as a bug to Linaro. -Ash On Wed, Jun 22, 2011 at 2:32 PM, Brad Midgley <bmi...@gm...> wrote: > Which module covers uart support? > > fwiw, usb host does not work for me in the stable gumstix image > either.

Ash > -- as of 2.6.36, OMAP serial ports appear on ttyOx not ttySx ok the good news is I can sometimes (!) get a 921k bluetooth connection with hciattach /dev/ttyO1 csr 921600 hciconfig hci0 if it reports "up" in hciconfig then it worked. anything else means it didn't and will require a reboot to try again. hciattach /dev/ttyO1 csr seems to always work, and anyway this connects at 115k. that limits what we can do with audio however. I haven't really been able to test things usb+hdmi because of some board weirdness. > USB Host: > --- I tried hotplugging a USB device directly into the USB host port Maybe my new tobi has a bad usb port. The host port never shows attached devices, although I can connect an old tobi and get usb host... as long as the hub is present at boot. but then hdmi won't work on the old board. I don't seem to have a combo that can give me everything. Is there a compatibility setting in uboot for older boards to get hdmi? -- Brad Midgley |

What I hadn't realized is I was mixing two different Tobi revisions---an older r2549 rev. and a newer version. The Linaro kernel is expecting to probe for an EDID via i2c to initialize a hdmi monitor. EDID support isn't connected, I believe, on the older Tobi boards hence there is an issue getting a display to function. Gumstix has always used the conventional 'defaultdisplay' argument to solve the issue. Does booting with omapdss.def_disp=dvi get the older Tobi display to work? -Ash |

fwiw... >> USB Host: >> --- I tried hotplugging a USB device directly into the USB host port > > Maybe my new tobi has a bad usb port. I found a combination of mainboard, tobi, hub, that do work. I'll look at it again tomorrow. My old usb2 hub seems to work fine everywhere else but didn't work with the new tobi board. I'm only rarely getting hciattach to play ball at 921k now in this combo. I'll just stick with 115k. -- Brad Midgley |

So Linaro works but with caveats... It only can drive hdmi on the latest tobi; my older tobi board works fine with Steve's images but linaro just has a blank screen. (Quick scan of boot messages didn't show a culprit) While bluetooth is on /dev/ttyO1 and I can sometimes hciattach it, occasionally even at 921k, I can't reliably initialize it. Symptom is hciattach succeeds, but hciconfig shows the adapter is down. This might be a timing thing for the attach command. Manually starting it is what occasionally works. This is a desktop linaro image fwiw. Ash, I know you got the bluetooth adapter to talk... were you able to attach it in a startup script or in some repeatable way? Brad |

All I did for testing bluetooth was, $ hciattach /dev/ttyO1 csr $ hcitool scan and saw that my laptop which has bluetooth showed up. I'm a bluetooth newbie so if you have other suggestions on how I should test, I'll happily give'em a go (and learn something useful in the process :).) Quick note: IIRC, you have a very recent rev com (r3118) in order to test the bluetooth PCM connection. Is bluetooth any more reliable on an older COM? -Ash |

I think Steve is bringing the new serial driver into his mainline so we should know before long if problems are common across lots of scenarios. -- Brad Midgley |

Oops - you can probably blame this on me: http://tinyurl.com/3e6ote7 I don't have an older Tobi, but let me know if this is indeed the issue. I can open a bug in Launchpad and revert this change. -andy |

No---I actually like your patch. In reality, I think the boot script should be respecting the value of the defaultdisplay environment variable from u-boot and changing the omapdss.def_disp parameter as appropriate for the kernel. That way, newer expansion boards with EEPROMs will automatically be configured for the correct display even if they don't have a probe-able EDID. Similarly, the kernel should only be trying to probe for EDID when omapdss.def_disp=dvi. Cheers, -Ash |
