PostPosted: Wed Jul 18, 2007 7:37 pm    Post subject: Generic ARM Stage 3 Install Reply with quote

Hello All,

I've been working on an Atmel AT91SAM9261 Evaluation Kit and so far have had great luck getting Linux booted up and running. This configuration uses uClibc and BusyBox to build everything you need...well to a point. The trouble is I'd really like to take advantage of X11 (or similar GUI platform) and I cannot get any of the GUI softwares to compile using the buildroot tool.

So, I'm thinking I should switch to mainstream glibc to get the compatibility I need to build X.org/TinyX. I tried setting up a RFS with Gentoo and ran into some problems. I tried two methods with little success and will outline them below.

Method 1 - Gentoo Handbook Install
1. Boot my platform into Linux (using buildroot RFS and Kernel)
2. Mount an NFS share from my x86 Linux Host on the target FS
3. Download stage 3 ARM tarball and portage tarball. Unpack them.
4. Go through the steps to configure the stage 3 tarball and chroot to the new RFS.
5. emerge --sync (FAILS!). Looks like the arm profile is too far out of date for the latest portage snapshots? Or maybe I'm out of memory (64MB)? Or maybe there are bugs with the DM9000 ethernet adapter?

So, I tried the method I used to get a bootable kernel for my OldWorld Mac...

Method 2 - Crossdev
1. emerge crossdev (on x86 host)
2. Trial and error installs of an arm toolchain (for arm-unknown-linux-gnu-) until one finishes without errors
3. Configure host system to cross compile via portage
4. emerge system (to get a RFS) (FAILS!). Looks like this combination of crossdev toolchain install doesn't work quite right?

So anyway, I'm sort of stuck now. Any ideas? Anyone know if there is a known, solidly working, combination of binaries to pass to crossdev to get a working gnu ARM toolchain?

Thanks!

Alright, I revisited method 1. I had a combination of problems before and they were:

1 - Not enough memory.
2 - Rsync timeout (after 180 seconds).

I resolved these by adding a swap file on a USB Thumb Drive and adding RSYNC_TIMEOUT=500 to make.conf. Now, I run emerge --sync and the process completes, but I have a TON of "Failed cache update:" messages. Anyways, I proceed because I probably need to emerge portage anyway (after all, it tells me I should)...

So, I try emerge portage and I get this error:
Code:

!!!ARCH is not set... Are you missing the /etc/make.profile symlink?
!!!Is the symlink correct?  Is your portage tree complete?


Lo and behold, when I check out the symlink, it points to a non-existent folder:
../usr/portage/profiles/default-arm-2004.0

So after updating to a current folder, such as /usr/portage/profiles/default-arm/2007.0 and running emerge portage, I get the same error as before. Thinking it might be too new, I try instead the other profile folder, /usr/portage/profiles/default-arm/2004.3. I now get this error after trying emerge portage:
Code:

!!! 'str' object has no attribute 'insert'
!!! 'rm -Rf /usr/portage/profiles; emerge sync' may fix this.  If it does
!!! not then please report this to bugs.gentoo.org and, if possible, a dev
!!! on #gentoo (irc.freenode.org)


Now this seems to be a bit of paradox...I guess I can try blowing away the profiles folder, but I have a feeling that isn't going to work. I'll give it a try. In the meantime, any ideas?

A new update!

I messed around for a while and discovered I had yet another error in my sync session. I increased the timeout value again (this time to 1000, I am using a 200 MHz ARM after all ;-)) and ran the sync again...it finished with complete success this time (no errors anywhere in the log).

Now about the profiles. It looks like both 2004.3 and 2007 are broken. I unwittingly tried the base profile (/usr/portage/profiles/default-linux/arm) and it works without either of the errors I received before.

Now I've got to update my clock and try again to make sure the builds are good :-).

This is what I have on my PDA. And it works.

Hi Civil,

I'm wondering what arm core your PDA uses. Most I know of run ARMv4 (strongARM or XScale) which is what the stage3 gentoo tarballs seemed to be configured for. My core is the ARM926EJ-S (using ARMv5TEJ instruction set), so I'm working on re-bootstrapping the stage3 tarball for ARMv5TEJ.

Also, which stage3 tarball did you use? I used the one under [gentoo mirror]/experimental/arm/stages/arm. Maybe the 2007.0 profile is correct using the armv4l tarball?

After updating portage and re-syncing, I am able to use the 2007.0 profile. Here's the new path from my host PC:
Code:

TestEnv1 buildroot-atmel # ls -al /nfs/gentoo/etc/make.profile
lrwxrwxrwx 1 root root 46 Jul 24 08:16 /nfs/gentoo/etc/make.profile -> /usr/portage/profiles/default-linux/arm/2007.0


So it seems the generic arm stage3 tarball is out-of-date and portage must be updated (in case the 2004 timestamp on the tarball didn't give enough clue). To get a working portage system after unpacking the latest portage tree to /usr, I did the following:

Code:

rm /etc/make.profile
ln -snf /usr/portage/profiles/default-linux/arm /etc/make.profile
emerge --sync
emerge portage # May need to disable acl support: USE="-acl" emerge portage
emerge sandbox # To remove sandbox error messages...you may be OK not to do this
etc-update # After emerge sandbox, I auto-merged the new configs
rm /etc/make.profile
ln -snf /usr/portage/profiles/default-linux/arm/2007.0 /etc/make.profile


Now I get an error with the gcc-4.1.2 ebuild while running /usr/portage/scripts/bootstrap.sh. Will post again after a retry.

Here's the error (I used the 2007.0 profile this time for bootstrap.sh):

I wonder if I can specify an earlier version of gcc (like 4.0.2 or 3.3.6)...

Alright, so I have a question. I tried to force a different gcc version and it shows that gcc 4.1.2 is still going to be emerged.

Code:
TestEnv2 ~ # emerge --pretend =sys-devel/gcc-3.4.6-r2

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] sys-devel/gcc-config-1.3.16 [1.3.5]
[ebuild  N    ] dev-libs/gmp-4.2.1-r1 USE="-doc -nocxx"
[ebuild  N    ] dev-util/unifdef-1.20
[ebuild     U ] sys-apps/findutils-4.3.7 [4.1.20-r1] USE="nls* -static%"
[ebuild  N    ] sys-libs/timezone-data-2007e USE="nls"
[ebuild     U ] sys-kernel/linux-headers-2.6.20-r2 [2.6.5]
[ebuild  N    ] sys-devel/binutils-config-1.9-r4
[ebuild  N    ] dev-libs/mpfr-2.2.1_p5
[ebuild     U ] sys-devel/binutils-2.17 [2.15.90.0.3-r3] USE="-multislot% -test% -vanilla%"
[ebuild  NS   ] sys-devel/gcc-4.1.2 USE="fortran mudflap nls (-altivec) -bootstrap -build -d -doc -gcj -gtk (-hardened) -ip28 -ip32r10k (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla"
[ebuild     U ] sys-libs/glibc-2.5-r4 [2.3.2-r10] USE="nptl* nptlonly%* -debug% -glibc-compat20% -glibc-omitfp% (-hardened) (-multilib) -profile% (-selinux)"
[ebuild  NS   ] sys-devel/gcc-3.4.6-r2 USE="fortran nls (-altivec) -bootstrap -boundschecking -build -d -doc -gcj -gtk (-hardened) -ip28 -ip32r10k (-multilib) -multislot (-n32) (-n64) -nocxx -nopie -nossp -objc -test -vanilla"


Which means I would still have the problem I posted previously. Why does portage want me to emerge gcc 4.1.2 to install gcc 3.4.6??

I looked up gmsgfmt and found it is a link to msgfmt which is part of gettext. Gettext isn't in the emerge list above, so I am going to emerge the latest "stable" gettext and try to build gcc-4.1.2 again.

Edited the subject to be more applicable since I'm not trying crossdev any longer.

Yeah, so emerging gettext again didn't help...

Any progress on this one?
I wouldn't have so much trouble if the stage tarball was outdated.
I'm starting with emerging the entire system crosscompiled with buildroot crosscompiler...
