Fedora ARM 12 on IGEPv2 (Beagle Board clone)
by Matthew Wilson 01 Jan '16

01 Jan '16

Hi all, I would like to introduce myself to the group. I have recently received an IGEPv2 board [1], which is based on the Beagle Board, but with wifi, bluetooth, ethernet, and more RAM. I'm still at the "wow, it's tiny and it runs Linux" stage. I should get a bit more time over the next month and Christmas to play around properly with it. I'm new to embedded development, but neither new to Linux nor ARM (writing my first ARM assembly some 15 years ago). However, for the past 6 years I've not even built a Linux kernel, preferring to use the default kernel in Fedora for simplicity :) Firstly, a thank you to those involved in Fedora ARM for getting it to this stage. If I get the time, I'd really like to contribute some (probably small) effort to help get Fedora ARM working well on the IGEPv2 and Beagle Board. As I progress, I'd like to know what I can do to help. In the meantime, I have some questions. Apologies in advance if these seem simple. 1) There are various different kernels from different sources. I'm used to there being a small set of "right" kernels (that is, Fedora's idea of "right") for x86. I fully appreciate that different ARM-based boards are quite different in capabilities (like different instruction set variants). a) Is there likely to be some standardised vanilla Fedora ARM kernel source? (Or is that simply the source RPM available for Fedora?) Then patches /could/ be offered for the more common systems (e.g. Beagle Board & clones, SheevaPlug). b) Would it then make sense to offer these as pre-built RPMs for common systems? c) Is there any guidance on which version is good to use as a base? I've seen quite different kernel versions being used (from 2.6.27 to 2.6.31). 2) I understand a little bit about the different calling conventions, FP differences (e.g. soft FPU versus VFP), and instruction set differences (v5 versus v7). a) Can the kernel can be safely built with a different instruction set targeted? (I know there are different optimisation options passed to GCC. Apologies if this seems a bit newbie-ish.) b) For FP-heavy programs (e.g. ogg encoding), is it possible to build the packages with VFP/NEON but still get them to work in a soft FPU system? I'd imagine any call to an external library would have to somehow be defined to use a different calling standard. 3) There seem to be some missing dependencies in the packages in the current Fedora ARM repository. For example, emacs is requiring libotf, which doesn't seem to be there in the repository. And likewise with the xorg-x11-font* packages needing ttmkdir. I'm confused as to how the RPM could have been successfully built without it. What am I missing? 4) I see there has been some discussion over unaligned data access. (Oh, I remember that from the ARM2 days.) It seems as if the Cortex-A8 cores allow unaligned data access when set up to do so [2]. Does this, in any way, help with the compatibility of packages targetting Cortex-A8? 5) I've managed to get various source packages missing from the Fedora ARM repositories to compile successfully (natively). I guess there is a reason why there are not in the repos right now -- is that reason down to time and priorities, or is there some blocking bugs with many of these packages? I look forward to being able to contribute something back into Fedora! Kind regards, Matthew [1] http://www.igep-platform.com/index.php?option=com_content&view=article&id=4… [2] http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0344j/Beihgi…

Regenerating the cross stuff
by Andy Green 31 Jul '10

31 Jul '10

Hi - I'm interested in regenerating the cross compiler packages, first just as it, then maybe uplevelling it and eventually to use the same technique to get a set of packages for MIPS cross compile. I found some SRPM goodies here: http://ftp.linux.org.uk/pub/linux/arm/fedora/cross/latest/source/ I thought I would try first to recook gcc-4.1.2-33.fa1.cross5.src.rpm without changes as a sanity check using this rawhide x86_64 laptop. First it wanted firefox-devel that doesn't exist any more, but I did the rebuild with --nodeps (all other deps are there) and build_java=0 to get around that for now. The build chokes out with: warning: line 168: prereq is deprecated: Prereq: /sbin/install-info warning: line 352: prereq is deprecated: Prereq: /sbin/install-info warning: line 417: prereq is deprecated: Prereq: /sbin/install-info warning: line 429: prereq is deprecated: Prereq: /sbin/install-info warning: line 494: prereq is deprecated: Prereq: /sbin/install-info warning: line 530: prereq is deprecated: Prereq: /sbin/install-info Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.Vh8YUW + umask 022 + cd /projects/mips/cross/rpmbuild/BUILD + cd /projects/mips/cross/rpmbuild/BUILD + rm -rf gcc-4.1.2-20070925 + /usr/bin/bzip2 -dc /projects/mips/cross/rpmbuild/SOURCES/gcc-4.1.2-20070925.tar.bz2 + /bin/tar -xf - + STATUS=0 + '[' 0 -ne 0 ']' + cd gcc-4.1.2-20070925 + /bin/chmod -Rf a+rX,u+w,g-w,o-w . + echo 'Patch #1 (gcc41-ice-hack.patch):' Patch #1 (gcc41-ice-hack.patch): + /bin/cat /projects/mips/cross/rpmbuild/SOURCES/gcc41-ice-hack.patch + /usr/bin/patch -s -p0 -b --suffix .ice-hack~ --fuzz=0 + echo 'Patch #2 (gcc41-ppc64-m32-m64-multilib-only.patch):' Patch #2 (gcc41-ppc64-m32-m64-multilib-only.patch): + /bin/cat /projects/mips/cross/rpmbuild/SOURCES/gcc41-ppc64-m32-m64-multilib-only.patch + /usr/bin/patch -s -p0 -b --suffix .ppc64-m32-m64-multilib-only~ --fuzz=0 1 out of 1 hunk FAILED -- saving rejects to file gcc/config/rs6000/t-linux64.rej error: Bad exit status from /var/tmp/rpm-tmp.Vh8YUW (%prep) Well, quite possibly I am missing the point badly, for example I don't know why there are three SRPMs for everything in that dir. If anyone has any tips or knowledge to share I would love to be able to uplevel and use this stuff with MIPS. -Andy

Kernels for common arm devices
by Peter Robinson 30 Jul '10

30 Jul '10

Hi All, With the ARM secondary arch slowly ramping up and more cheap arm devices becoming available I think it would be useful to provide some ARM kernel images for some common devices out there to make it easier for developers and testers to get involved without having to compile their own kernel first. How hard would this be to do, sort of like i386 provides a PAE and non PAE kernel. I think the 3 devices that would be a good start are the ones that are already running in the koji instance as they are commonly available and someone has obviously done the work to work out what is needed. >From there the other devices that come to mind are the Nokia n900 (should be able to borrow the kernel config from MeeGo) and BeagleBoard (I think MeeGo has one for this too). It might even be possible to use the MeeGo kernels with a Fedora rootfs. Thoughts? Cheers, Peter

Mybook World, old edition

29 Jul '10

Trying to get Fedora running on an old Mybook World, but can not seem to get it to run at all.. >From what I understand this is the same that Peter Lemenkov successfully got Fedora 11 running on some time ago, but I only get "illegal instruction" when trying to run anything.. I am using the original kernel shipped by WDC. Regards Henrik

Kernel failing to boot at guruplug

Hi I finally got a running kernel compiled, flashed it successfully and got it to boot halfway. The only thing being missing is the console coming up. Here is the boot sequenz, and I think the kernel lacks a driver, but I do not understand which one is missing from that output.

How to get started?
by Andrew van der Stock 14 Jul '10

14 Jul '10

Hi there, I've offered to help with the OLPC ARM port for OLPC 1.75. Obviously this hardware doesn't exist yet, so I have a few questions. I've just installed x64 F13 and got a Fedora account. 1. How is the best way to get started? 2. Should I get a cross-compiler going, and pick a package to port? Obviously, I'd prefer to work on the packages that OLPC 1.75 will need, but am happy to work on anything you need. 3. How can I test the resulting RPM? 4. I'm going to be in the US next week for OSCON. I will try to pick up a Beagle Board or GuruPlug, but it seems like supply is severely constrained for any / all of the suitable ARM boards. As the OLPC 1.75 and XO-3 will use Marvell parts, will ARM-A8 boards be a suitable target, or should I go with a Marvell based device? I have long lost experience with kernel programming (porting Reiserfs and other ports to Alpha back in 2000 or so, when LP big endian 64 bit was very rare), X11 drivers (Matrox cards) for XFree86 back in the 1990's and pnm2ppa - a printer driver for HP's worst ever printers. thanks, Andrew p.s. I have three XO-1's, but obviously these are not that useful for this effort unless parity is achieved for the OS with the 1.75.

Fedora on NSLU2
