HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net In this HOWTO I'd like to explain how to compile a custom 2.6.38.8 kernel for the GoFlex Net. I did this on Kubuntu 11.04 but I guess that every other Debian based distro should be fine as well. First we should install the necessary packages: [code] sudo apt-get install aptitude libncurses5 libncurses5-dev qt3-dev-tools libqt3-mt-dev build-essential fakeroot kernel-package libncurses5 libncurses5-dev patch [/code] Now we want to setup the codesourcery compiler via [i]setup_codesourcery.sh[/i] script by Matthias "Maddes" Buecher. I attached the script to this post, but you can find this script on many sites, for example [url=http://www.nas-central.org/wiki/Setting_up_the_codesourcery_toolchain_for_X86_to_ARM9_cross_compiling#Installing_CodeSourcery.27s_Toolchain]here[/url]. We can simply get the script via wget [code] mkdir ~/Kernel cd ~/Kernel wget http://ftp.maddes.net/hardware/Linkstation/setup_codesourcery.sh [/code] Now let's install the compiler [code] chmod +x setup_codesourcery.sh sudo ./setup_codesourcery.sh [/code] We also need a kernel patch for the GoFlex Net. I got one mine from [url=http://www.varkey.in/files/goflex-2.6.37.6-p1.patch]varkey's page[/url] but I had to delete the last 7 lines since they were already in the kernel source. So just download the [i]goflex-2.6.38.patch[/i] file I attached to this post and put it to ~/Kernel. What you also need is a kernel config file. To make things a bit easier I've already attached one ([i].config[/i]) for you. You must put it to ~/Kernel too. Ok, let's get the kernel source and extract it [code] wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.8.tar.bz2 tar xjvf linux-2.6.38.8.tar.bz2 cd linux-2.6.38.8 [/code] The next step is to patch the kernel and copy the config file [code] patch -p1 < ../goflex-2.6.38.patch cp ../.config . [/code] After that we go to the crosscompile environment and import the config. [code] codesourcery-arm-2009q3.sh make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- oldconfig [/code] At this stage you might be asked some questions about kernel options (probably not). It's safe to answer all questions by hitting [i]Enter[/i] which means accepting the default setting. Now you can perform the custom configuration of your kernel [code] make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- xconfig [/code] For the first time I suggest that you don't change anything, just to make sure that your custom kernel boots at all. Later you can recompile the kernel and change whatever you want. Finally, let's build the kernel [code] make-kpkg --rootcmd fakeroot --arch armel --cross-compile arm-none-linux-gnueabi- --append-to-version=-goflex --revision=1.1 --initrd binary [/code] On my laptop with C2D T5500 and 3GB RAM the build process takes about 40 Minutes. When finished, in ~/Kernel you will find a file called [i]linux-image-2.6.38.8-goflex-ubit_1.1_armel.deb[/i]. Copy this to your GoFlex Net, for example to /root. [code] scp ~/Kernel/linux-image-2.6.38.8-goflex-ubit_1.1_armel.deb root@ip-of-the-goflex:/root [/code] Now login to your GoFlex Net via ssh and install the kernel [code] ssh root@ip-of-the-goflex -> Pass cd /root dpkg -i linux-image-2.6.38.8-goflex-ubit_1.1_armel.deb [/code] The last step is to create uImage und uInitrd for uBoot/UBIT but also backup to the old ones [code] cd /boot cp uImage uImage.old cp uInitrd uInitrd.old mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-2.6.38.8 -d /boot/vmlinuz-2.6.38.8-goflex-ubit /boot/uImage mkimage -A arm -O linux -T ramdisk -C gzip -a 0 -e 0 -n Linux-2.6.38.8 -d /boot/initrd.img-2.6.38.8-goflex-ubit /boot/uInitrd [/code] Done! Next time you reboot your GoFlex Net it should boot with the new kernel. If something goes wrong, just connect your USB/HDD with the rootfs to a Linux machine, mount the filesystem and do [code] cp /path-to-rootfs/boot/uImage.old /path-to-rootfs/boot/uImage cp /path-to-rootfs/boot/uInitrd /path-to-rootfs/boot/uInitrd [/code] This will give you the old kernel back [b]Finding the right boot partition[/b] GoFlex Net has problems to boot from a USB flash drive when there are SATA hard drives attached. The solution you have to apply depends on whether you have Jeff's u-Boot bootloader or the UBIT bootloader. [list] [*] If you initially installed Debian using [url=http://jeff.doozan.com/debian/] Jeff's script [/url] then you have u-Boot. [*] If you initially installed Arch using instructions from the [url=http://archlinuxarm.org/] Arch Linux ARM [/url] site then you have UBIT [/list] Independent of the solution you are going to use, it's mandatory to label your rootfs partition as "rootfs". To do this, connect your USB flash drive to a Linux box and issue [code]sudo tune2fs -L "rootfs" /dev/whatever[/code] where /dev/whatever is the path to the partition containing the rootfs for GoFlex Net [b]Solution for uBOOT[/b] On the GoFlex run [code]fw_setenv usb_init "run usb_scan; setenv usb_root LABEL=rootfs"[/code] after that reboot and you're done. For more information on this solution check out [url=http://forum.doozan.com/read.php?2,5552,5552] this thread [/url] [b]Solution for UBIT aka hacked initrd[/b] If you have UBIT you still may try the uBOOT solution but the chances are high that it simply won't work. In this case you should do the following. On the GoFlex Net run [code] cd /boot mkdir initrd.img-new cp initrd.img-2.6.38.8-goflex-ubit initrd.img-new/ cd initrd.img-new/ gzip -dc initrd.img-2.6.38.8-goflex-ubit | cpio -id rm initrd.img-2.6.38.8-goflex-ubit nano init [/code] Find the section which looks like [code] if [ -n "${noresume}" ]; then export noresume unset resume else resume=${RESUME:-} fi [/code] and replace it by [code] if [ -n "${noresume}" ]; then export noresume unset resume else resume=${RESUME:-} fi ROOT="/dev/disk/by-label/rootfs" [/code] Save your changes (Ctrl+W) and exit (Ctrl+X) nano. Now run [code] find ./ | cpio -H newc -o > initrd.img-2.6.38.8-goflex-ubit gzip -9 initrd.img-2.6.38.8-goflex-ubit mv initrd.img-2.6.38.8-goflex-ubit.gz ..//initrd.img-2.6.38.8-goflex-ubit_mod cd .. rm -r initrd.img-new mkimage -A arm -O linux -T ramdisk -C gzip -a 0 -e 0 -n Linux-2.6.38.8 -d /boot/initrd.img-2.6.38.8-goflex-ubit_mod /uInitrd [/code] The purpose of all this is to hardcode a rootfs partition. In this case we tell the kernel (via initramfs) that the rootfs partition is a partition with the label "rootfs". This is a very ugly hack but it works when everything doesn't. [b]Hacking kernel sources[/b] In ~/Kernel you will also find a package containing kernel sources (linux-image-2.6.38.8-goflex-ubit_1.1_armel.deb) that might be necessary for compiling some modules/utilities on the GoFlex Net. For some reason this package contains a lot of X11 related dependencies which are definitely not needed for a headless server. I solved this by simply removing those by hand. [code] cd ~/Kernel dpkg-deb -x linux-headers-2.6.38.8-goflex-ubit_1.1_armel.deb linux-headers-2.6.38.8-goflex-ubit_1.1_armel_hacked dpkg-deb -e linux-headers-2.6.38.8-goflex-ubit_1.1_armel.deb linux-headers-2.6.38.8-goflex-ubit_1.1_armel_hacked/DEBIAN nano linux-headers-2.6.38.8-goflex-ubit_1.1_armel/debian/control [/code] replace [code] Depends: libaudio2, libc6 (>= 2.8), libfontconfig1 (>= 2.8.0), libfreetype6 (>= 2.2.1), libgcc1 (>= 1:4.1.1), libice6 (>= 1:1.0.0), libjpeg62 (>= 6b1), libpng12-0 (>= 1.2.13-4), libqt3-mt (>= 3:3.3.8-b), libsm6, libstdc++6 (>= 4.1.1), libx11-6, libxcursor1 (>> 1.1.2), libxext6, libxft2 (>> 2.1.1), libxi6, libxinerama1, libxrandr2, libxrender1, libxt6, zlib1g (>= 1:1.1.4) [/code] by [code] Depends: libc6 (>= 2.8), libgcc1 (>= 1:4.1.1), libjpeg62 (>= 6b1), libpng12-0 (>= 1.2.13-4), libstdc++6 (>= 4.1.1), zlib1g (>= 1:1.1.4) [/code] and do [code] dpkg-deb -b linux-headers-2.6.38.8-goflex-ubit_1.1_armel_hacked [/code] After that you can install the modified package the usual way.

I need to patch in the LED's still. Not sure if I want to use Jeff's&Carmichaels' code for that, or try to tie it in very closely with the already-existing KW_GPIO & mvgpio stuff.

BTW, the u-boot-2012.03-stable release is really just weeks or days away.]]> davygravy Debian Fri, 23 Mar 2012 10:58:32 -0400 http://forum.doozan.com/read.php?2,5775,7419#msg-7419 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,7419#msg-7419 Vlad Debian Fri, 23 Mar 2012 07:34:05 -0400 http://forum.doozan.com/read.php?2,5775,7406#msg-7406 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,7406#msg-7406 -------------------------------------------------------

I wonder if there is a way to fix u-boot so this misidentification cannot happen.

I've now got a u-boot 2011.12 patched with the L2Cachedisable feature, and it works w/ the usb rootfs (with the roofs label method). It will boot 3.2, 3.3 kernels, no kernel panic. BTW, I have it identified with machid = eSATA Sheevaplug.

the rootfs will be mounted as ext3 if it is formatted as ext3.

And you are right, it only works with the righthand (from the front) SATA-Slot. (booting from two devices is very unconventional ;) )

Now I have only to find out the U-Boot settings for Sheeva, to use the one and only kernel and rootfs on all devices (Dockstar, Goflex and Sheeva)!

If I have a rescue system on the NAND is the boot behavior like this:

1. USB-Stick
2. SATA HD
3. Rescue System

Or does Goflex only boot from SATA after the modifications ?

I tried to boot from SATA, but that don't work for me. Do you have any idea?

If you are using Jeff's uBoot, by default it will not boot from a SATA drive even if you have installed a kernel which supports the SATA ports.

You need to change the uBoot settings so that it can initialize the SATA ports and load the Kernel and Initrd from the SATA disk. These are the changes that I made 

fw_setenv sata_boot 'ide reset; mw 0x800000 0 1; ext2load ide 0:1 0x800000 /boot/uImage; if ext2load ide 0:1 0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi'
fw_setenv sata_bootcmd 'run usb_set_bootargs; run sata_boot'
fw_setenv bootcmd 'usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run sata_bootcmd; run rescue_bootcmd; run pogo_bootcmd; reset'

Edit : Booting from SATA is very much possible with Jeff's uBoot, and UBIT is *NOT* necessary. I have done it as described in my blog

http://www.varkey.in/2011/06/boot-debian-from-sata-seagate-goflex-net/

What I understood is: Booting from SATA is only possible with UBIT. What about this:

http://www.varkey.in/tag/goflex-net/

Does this modification work?

fw_setenv sata_boot 'ide reset; mw 0x800000 0 1; ext2load ide 0:1 0x800000 /boot/uImage; if ext2load ide 0:1 0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi'

fw_setenv bootcmd 'usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run sata_bootcmd; run rescue_bootcmd; run pogo_bootcmd; reset'

I can boot fine from my USB-attached SATA drive, but in a SATA-Port it fails booting.

If an expert like to take a look at my GoFlex Net we could arrange that.

The only difference between Jeff's Uboot and the UBIT installed Uboot, as far as I understand, is that the UBIT installed one allows booting from SATA. Jeff's UBoot does not because I don't think it can sense the SATA ports. The booting issues arise because Linux udev will identify the SATA disks when the initrd is loaded. The SATA ports will get identified as /dev/sda1 and /dev/sda2, while Jeff's Uboot thinks /dev/sda1 is the first USB port where your root file system is locationed. Setting the root as a LABEL for Uboot works around the identification mismatch. But if you want to boot from SATA, I think UBIT is the only option.

But I have no idea why the UBIT Uboot doesn't pass the root correctly. The boot loader's job is to load the kernel and an initrd into memory, and then execute the kernel with some parameters. UBIT should work the same as Lilo, Grub, Grub2, and Jeff's Uboot. The loaded initrd is then supposed to handle converting the root as UUID or LABEL into a device using the udev symlink. (It's in the init script.) The UBIT Uboot shouldn't be searching for anything. After loading, and after the boot delay countdown expires, its supposed to execute bootcmd.]]> kraqh3d Debian Sat, 10 Sep 2011 11:12:41 -0400 http://forum.doozan.com/read.php?2,5775,5862#msg-5862 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5862#msg-5862

I decided to use Jeff's bootloader and maybe to install the rescue-system on NAND. I think that's a good setup as well.

The SATA ports are working from this setup.

I tried to boot from SATA, but that don't work for me. Do you have any idea?

then I repeated the same test with a USB hub and 4 flash drives but no HDDs. Surprisingly it still works. But as soon as you connect the hard drives is doesn't. I guess that's because UBIT by default searches for partitions labeled "rootfs" without really respecting the environment options. Still this fails when hard drives are attached.

You'll notice my usb_root variable is near the bottom. My initial attempts of just trying to change usb_root didn't work. I had to experiment with serial access, where I stopped the boot sequence and ran through the process manually. I found that you have to correct usb_root after usb_scan but before usb_set_bootags, or change the entire process which didn't seem worth it.

It's very strange that removing the hard drives makes it work for you. I can't see how that would make a difference.]]> kraqh3d Debian Fri, 09 Sep 2011 21:59:10 -0400 http://forum.doozan.com/read.php?2,5775,5849#msg-5849 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5849#msg-5849
I've just tried to pass 
#fw_setenv usb_bootcmd "run usb_init; run usb_set_bootargs; usb_root=LABEL=rootfs; run usb_boot"
which is like the closest point you can get.

This gave me some interesting results. First I've tried the usual way: rootfs on a USB flash drive + 2 data HDDs -> no luck. Then I removed the HDDs and connected a USB hub with 4 USB flash drives. To my surprise, this time LABEL=rootfs worked! 

cat /proc/cmdline
console=ttyS0,115200 mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data) root=/dev/sdd1 rootdelay=10 netconsole=@10.0.10.6/eth0,@10.10.10.4/

This means, the option is applied but somehow the presence of HDDs seems to confuse UBIT that much, that it fails to provide a proper USB boot.

The hd_args and usb_args seem like attempts to do the same thing, but I dont see them being referenced anywhere.

Booting from a label or uuid is the better way to go. You're doing that by force the init script to look for a particular hard coded label.

It works on my GoFlex Net, that's all I can say. By the way, if you followed my guide, you should still have your old uImage and uInitrd named uImage.old and uInitrd.old. If you rename them to uImage and uInitrd your GoFlex should boot as it did before.

While I agree that my workaround is nothing more than an ugly hack, I must also warn, that the "cleaner solution" doesn't work with UBIT, only uBOOT. I've just did a little experiment:
  • Took my GoFlex Net with UBIT v0.6
  • Took Jeffs' 2.6.37 kernel and unmodified initrd from my custom kernel
  • Changed the firmware environment as described 
#fw_setenv usb_init "run usb_scan; setenv usb_root LABEL=rootfs" 
#fw_printenv | grep usb_init
usb_init=run usb_scan; setenv usb_root LABEL=rootfs
  • The rootfs partition is of course labeled "rootfs"
  • Booted without any harddrives attached.
Check out the kernel parameters: 
cat /proc/cmdline
console=ttyS0,115200 mtdparts=orion_nand:1M(u-boot),4M(uImage),32M(rootfs),-(data) root=/dev/sda1 rootdelay=10 netconsole=@10.0.10.6/eth0,@10.10.10.4/
    Now reboot with both HDDs attached and watch the boot process via netconsole

A kernel panic, which, however, doesn't make much difference. I really think that this has something to do with UBIT because all the people from the thread you linked seem to use uBOOT.]]> Vlad Debian Fri, 09 Sep 2011 17:47:31 -0400 http://forum.doozan.com/read.php?2,5775,5831#msg-5831 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5831#msg-5831 http://forum.doozan.com/read.php?2,5552,5552

You don't need to modify with the init script from the initrd image. The init script does this already by default if you just simply pass the kernel the root locaton using a label. For your example above, you just need to pass the kernel "root=LABEL=rootfs".]]> kraqh3d Debian Fri, 09 Sep 2011 16:52:52 -0400 http://forum.doozan.com/read.php?2,5775,5830#msg-5830 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5830#msg-5830 thanks for that! Are you sure this should work? I tried it from my working DS, because I can't do it on a non working GF.

The kernel boots fine with Jeff's bootloader and I think I can live with that.

My other problem is the SheevaPlug device. I like to use the same image with the same kernel on Sheeva, but I got lost. Have you done this? Do you know the UBoot environment parameters to boot a DS Image (ported to MMC) on Sheeva?

Thomas]]> squeezeplug Debian Fri, 09 Sep 2011 16:52:31 -0400 http://forum.doozan.com/read.php?2,5775,5827#msg-5827 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5827#msg-5827 -------------------------------------------------------

Looks like the kernel can't find your rootfs. Actually, I had a similar issue and even posted a solution in one of my earlier
posts (by the way a quite informative one), but because some people argued that they didn't experience this kind of problems, I left it out here. Anyway, I've updated the guide once again, covering that final step ("Hacking initrd"). Hope it helps.]]> Vlad Debian Fri, 09 Sep 2011 14:20:45 -0400 http://forum.doozan.com/read.php?2,5775,5826#msg-5826 Re: HOWTO: Build a custom 2.6.38.8 kernel for Goflex Net http://forum.doozan.com/read.php?2,5775,5826#msg-5826 Ralphy and me build a kernel with your config.

Do you have an idea?
