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…

Announcing Fedora 19 ARM remix for Allwinner SOCs release 3
by Hans de Goede 09 Aug '14

09 Aug '14

Hi All, I'm very happy to announce the third release (r3) of my Fedora 19 ARM remix images for Allwinner A10, A10s, A13 and A20 based devices. This release is based on the official Fedora 19 Final for ARM images, with u-boot and kernel(s) from the linux-sunxi project: http://linux-sunxi.org/ New this release: 1) Fix the bad brown paper bag bug in r2 which caused it to not boot on sun4i (A10) and sun5i (A13/A10s) devices 2) Support for the cubietruck (except for the wifi module) 3) Support for the Megafeis A08 and Mini-X with A10s You can download it here: http://people.fedoraproject.org/~jwrdegoede/a10-images/Fedora-19-a10-armhfp… sha1sum: a57e5897e0c6047dbb473c438016d6364fd0709f It is important to read the README, the image standard comes without u-boot pre-loaded since u-boot is board specific. The image includes a user-friendly simple script to install the right u-boot for your board, but if you simply xzcat the image to an sdcard, and then boot your device with the sdcard, things will *not* work. See the README for a list of currently supported boards. Known Issues: -Many boards don't have an rtc (A10 and A20 have a builtin one), or at least no battery backup for it, resulting in the date + time being wrong. -If the date is of by more then a couple of months, "yum update" won't work because certificate validation fails for the https connection yum tries to make. So if yum fails to get its repodata first check (and fix) your date -The regular (host not otg) usb-port on A10s based boards can be a bit quirky. It is best to plug in a hub even when using only one device, otherwise the device may not be recognized. If this happens, after adding a hub, often a power-cycle is needed too. -The wifi chip on the Auxtek-T004 hdmi-stick and on the cubietruck are unsupported atm Enjoy, Hans And to make sure everyone reads the README, let me print it here in full: Fedora 19 ARM for Allwinner A10, A10s, A13 and A20 devices README ----------------------------------------------------------------- Quickstart guide ---------------- 1) Insert an sdcard, note any data on the card will be destroyed! 2) Make sure the card is not mounted, run "mount" and if the card shows up in the output umount its partitions 3) Write the img file to the card, ie as root do: xzcat Fedora-19-a10-armhfp-r2.img.xz > /dev/mmcblk0 sync 4) The card is not yet ready for use! Since the A10 u-boot is board specific, the image comes without any uboot install, follow the next steps to install the right u-boot for your board 5) Remove the card, and re-insert it. The uboot partition should get automatically mounted, if not mount it manually, 6) As root (or through sudo) run: <uboot-part-mount>/select-board.sh, ie: sudo /run/media/hans/uboot/select-board.sh If you've dialog installed the select-board.sh script will prompt for your board. If you don't have dialog installed, it will print the list of supported boards. Lookup your board and re-run the script with the shortname for your board as argument, ie: sudo sh /run/media/hans/uboot/select-board.sh mk802 7) umount the uboot and rootfs partitions, ie: umount /run/media/hans/uboot umount /run/media/hans/rootfs 8) Your sdcard is now ready for use 9) *Before* powering up your A10 device connect it to an hdmi or dvi monitor 10) When first booting from the sdcard inserted Fedora will automatically reboot once, this is part of the process to resize the root partition to fill the entire sdcard and is normal behavior. 11) After the automatic reboot Fedora will start with the initial-setup wizard: 11a) Configure networking, note: * If you've an A10 board with wired ethernet and you want to use dhcp you don't need to do anything. * If you've an A20 board, your ethernet may have a random mac-address, so if you want to configure a static ip-address and want it to stick across reboots, go to the ethernet-tab, select the mac-address field and delete its contents, so that the static ip address you're configuring does not get tied to the random mac-address. 11b) Setup the time zone 11c) Set a root password 11d) Create a user 12) Log in as the just created user 13) Enjoy Fedora on your A10 device Supported Devices: ------------------ Fedora 19 ARM for Allwinner A10 has been tested with the following devices: * A10s-OLinuXino-MICRO (Olimex) * A13-OLinuXino (Olimex) * A13-OLinuXino-MICRO (Olimex) * A20-OLinuXino-MICRO (Olimex) * Auxtek T003 hdmi tv stick * Auxtek T004 hdmi tv stick * BA10 TV Box * Cubieboard development board 1024 MB RAM * Cubieboard2 (A20) development board * Cubietruck development board * Gooseberry development board * Mele A1000G/A2000G 1024 MB RAM * Mini-X 1024 MB RAM * mk802 (with female mini hdmi) 512 MB RAM * mk802 with A10s (s with a circle around it on the barcode label) * mk802ii (with male normal hdmi) 1024 MB RAM * r7 hdmi tv stick * UHost U1A hdmi tv stick * Wobo i5 TV Box Fedora 19 ARM should also work on the following devices: * A10 tablet sold under various names (whitelabel) * A13 tablet sold under various names (whitelabel) * Coby MID7042 tablet * Coby MID8042 tablet * Coby MID9742 tablet * Cubieboard development board 512 MB RAM * DNS AirTab M82 tablet * EOMA68 A10 CPU card * H6 netbook * Hackberry development board * Hyundai a7hd tablet * iNet-97F Rev.2 (and clones) tablet * Marsboard A10 * Megafeis A08 * Mele A1000/A2000 512 MB RAM * Mele A3700 * Mini-X 512 MB RAM * Mini-X with A10s soc * mk802 (with female mini hdmi) 1024 MB RAM * pcDuino development board * Point of View ProTab 2 IPS 9" tablet * Point of View ProTab 2 IPS tablet with 3g * Sanei N90 * XZPAD700 7" tablet Configuring the display output ------------------------------ Multiple video outputs at the same time are not supported. By default hdmi output with EDID is used for all devices, except for tablets/netbooks where the default output is the lcd. The default hdmi output with EDID will get the native resolution of your TV / monitor and use that. Note that in order for this to work your TV / monitor must be connected *and turned on*, before booting your device. The output resolution can be configured with the disp.screen0_output_mode kernel cmdline value, which can be found in the extrargs part of uEnv.txt in the uboot partition. The default uEnv.txt contains the following value: disp.screen0_output_mode=EDID:1280x720p60 This means try to use EDID and if no valid EDID info is found fallback to 1280x720p60. The used output can be changed by adding disp.screen0_output_type=X to the extraargs in uEnv.txt. With X being one of: 0:none; 1:lcd; 2:tv; 3:hdmi; 4:vga Some per display type notes: -lcd outputs: Hardcoded to the native mode, disp.screen0_output_mode is ignored -tv: For the cvbs output disp.screen0_output_mode must be set to one of the following: pal, pal-svideo, ntsc, ntsc-svideo, pal-m, pal-m-svideo, pal-nc, pal-nc-svideo. Note the -svideo variants should only be used on boards with an svideo connector, for composite out use the regular variants, ie: disp.screen0_output_type=2 disp.screen0_output_mode=pal -hdmi: To override the EDID detected mode, drop the "EDID:" from the disp.screen0_output_mode value and set it to the desired mode, ie: disp.screen0_output_type=3 disp.screen0_output_mode=1360x768p60 -vga: Does not support EDID, "EDID:" must be removed from the disp.screen0_output_mode value otherwise it will be ignored. interlaced progressive and refreshrate settings specified are ignored, each resolution has hardcoded values for these. Example usage: disp.screen0_output_type=4 disp.screen0_output_mode=1024x768 How to power your allwinner device ---------------------------------- For reliable operation it is important that your allwinner device is properly powered. Some users try to power their allwinner development boards through the power pin on the serial port / uart connector. This is a very bad idea! and will almost always result in unreliable operation. Instaed always power your allwinner device over the barrel connector intended for that using, using a quality, reliable power supply. USB controller caveats ---------------------- The OTG USB controller in host mode only supports a limited number of devices, plugging in a hub + mouse + keyboard typically will make either the mouse or keyboard not work. This is a hardware limitation which we will likely not be able to work around. On tv-sticks and top-set boxes, simply avoid the otg connector, instead use a hub in a regular host usb connector. Note on the mini-x the otg / host marking is not always correct. If things don't work try using the OTG connector instead! On tablets and the gooseberry unfortunately only the otg connector is available. One solution there is using a single usb-device which is both a keyboard and a mouse at the same time. IE the receiver for logitech wireless desktop sets. Known Issues ------------ * The broadcom sdio wifi found in the Auxtek T004 hdmi-stick and on the Cubietruck is not supported Supported hardware components / features: ----------------------------------------- Fedora 19 ARM for Allwinner A10 supports the following components: * CPU + PMU + RAM * Serial ports * MMC cards * Internal NAND storage * Framebuffer on lcd / vga / hdmi / composite video * Sound both analog out and over hdmi * OTG USB controller * Both standard USB host controllers * Wifi * Wired Ethernet * SATA * IR (untested at this time) * SPI (as module, not supported on A20) * "tablet" keys on olinuxino boards * 7 and 10 inch lcd displays on olinuxino boards (requires selecting the right config in select-board.sh Unsupported hardware components: -------------------------------- The following components require various proprietary blobs to be used, and as such are not supported in the Fedora images. The kernel drivers for them are present (usually as modules), so if you add the necessary blobs you might get these to work: * Mali 400 GPU * Cedar hardware video & audio decoding and encoding engine * G2D 2d engine Note that the drivers for these need some memory to be reserved at boot, and since they are not supported by default in the Fedora images, this memory reservation has been disabled. To reserve the memory edit /boot/uEnv.txt and remove the kernel cmdline options which disable the memory reservation. Differences from stock Fedora ----------------------------- * Since the A10 is not a very powerful soc some services which are enabled by default on Fedora are disabled in the image, see build-image.sh for a list. * No plymouth: we log to a serial console for debugging so no pretty splash. Also we don't use an initrd, so removing the console=ttyS0,115200 from the extraargs in uEnv.txt will give plymouth, but so late it hardly matters. Rebuilding the Fedora 19 ARM for Allwinner A10 disk image --------------------------------------------------------- Building the Fedora 19 ARM for Allwinner A10 disk image consists of 2 steps 1) Building a uboot.tar.gz and rootfs.tar.gz "overlays", this is done bu the build-boot-root-sh script 2) Combining uboot.tar.gz and rootfs.tar.gz with an official Fedora 19 arm img, this combining is done by the build-image.sh script The a10 image you downloaded is based on Fedora-XFCE-armhfp-19-1-sda.raw These scripts are hosted here: https://github.com/jwrdegoede/sunxi-fedora-scripts.git A copy of the exact versions of these scripts used to build this Fedora A10 image can be found in the scripts directory of the uboot partition, the kernel config used during the build can be found here too. If you want to exactly reproduce this image it is important to use the scripts from the scripts dir of the uboot partition, as the scripts contain GIT tags used during the build to checkout the exact versions to build. The pre-conditions these scripts expect to be met, and the exact usage of them is documented in comments in the top of each script.

F20 Beta 5 (XFCE) remix for PandaBoard
by Jaromir Capik 23 Dec '13

23 Dec '13

Hello everyone. I created a Fedora 20 Beta 5 remix for Panda and would appreciate some tests. The image is XFCE only (can add more later). You can download the image here: http://jcapik.fedorapeople.org/files/ARM/f20-remixes/ Please, let me know whether it works for you ... NOTE: It uses the old F19 kernel as the new F20 kernel doesn't boot on Panda -> do not update the kernel. Thanks in advance. Regards, Jaromir. -- Jaromir Capik Red Hat Czech, s.r.o.

Any opinions on ODROID-XU ?
by Richard W.M. Jones 07 Dec '13

07 Dec '13

If you can stand a very slow web site: http://www.hardkernel.com/renewal_2011/products/prdt_info.php?g_code=G13751… There is apparently an unofficial Fedora 19 image which boots (http://forum.odroid.com/viewtopic.php?f=62&t=2366). I've no idea if/where they are making source available, or even if it needs patches. The hardware is interesting: - Cortex A15, hence at least the potential of virtualization support. It's not clear if there are any firmware roadblocks to this actually working. - 8 core big.LITTLE (ie. 4 x A15 + 4 x A7). Is there any support for this upstream yet? I read an article in LWN indicating it was rather complicated to support properly. - A bit low on RAM (2 GB). - A fan(!) Any opinions on this one?

I've successfully gone through the install / startup with that image, using a serial console cable. It just worked. I used F20 Beta on an x86_64 system with the Adafruit USB to TTL serial cable.

Performance on BBB
by Jos Vos 02 Dec '13

02 Dec '13

Hi, For a simple first impression of the performance (and because for me Python performance is important), I used pystone.py on the BeagleBone Black (http://svn.python.org/projects/python/trunk/Lib/test/pystone.py). Fedora: Pystone(1.1) time for 50000 passes = 10.9073 This machine benchmarks at 4584.1 pystones/second Debian: Pystone(1.1) time for 50000 passes = 4.38 This machine benchmarks at 11415.5 pystones/second Is there a good explanation for this? -- -- Jos Vos <jos(a)xos.nl> -- X/OS Experts in Open Systems BV | Phone: +31 20 6938364 -- Amsterdam, The Netherlands | Fax: +31 20 6948204

arm-temp.ausil.us is shutting down
by Brendan Conoboy 02 Dec '13

02 Dec '13

Hi everybody, Dennis's email server is currently migrating so I'm sending this for him. The system we did aarch64 bootstrap on, arm-temp.ausil.us, is shutting down. If you're currently using this system to retrieve packages you'll want to update your yum configuration to use http://arm-temp.ausil.us/pub/fedora-arm/stage4/ instead. Much thanks to Dennis for hosting the armv8 bootstrap coordination server- we couldn't have done it in the open without him. Rawhide builds on koji are now commencing. -- Brendan Conoboy / Red Hat, Inc. / blc(a)redhat.com

F20 Beta-5 on BeagleBone Black (solved/update)
by Jos Vos 29 Nov '13

29 Nov '13

Hi all, OK, thanks to all the tips and tricks from yesterday in my previous thread, I got F20 Beta-5 up and running on a microSD on the BBB, completely headless, with only a network cable. Some comments: - All the boot troubles were probably related to my attempts to push the boot button and expecting LEDs to turn on, not waiting long enough, etc. I see the instructions are adapted in the meantime. - The lines in the FAQ about deleting systemd service links can be removed, as they do not apply anymore for the F20 Beta-5 image and are confusing. - Just as a side note: I did not do the last 3 commands in the FAQ, but editted /etc/shadow on the image and copied an encrypted password that I know into the root entry. This might be easier for others too. - After booting, I resized mmcblk0p3 with fdisk, rebooted, and used resize2fs to resize the fs. Now one remaining question: is there a repository I can use for adding packages now or should I wait till F20 final is released? I want to do some experiments for applications I have in mind, for which I need to add several packages (and their dependencies. Thanks again for all help. I'll contnue experimenting with it. -- -- Jos Vos <jos(a)xos.nl> -- X/OS Experts in Open Systems BV | Phone: +31 20 6938364 -- Amsterdam, The Netherlands | Fax: +31 20 6948204

not able to mount sata root FS when booting F20 on Wandboard quad
by Ronald 29 Nov '13

29 Nov '13

I have a wandboard quad, and would like to mount a sata root FS at boot time. kwizart helped me to get sata support when booting by doing the following: --- instructions from kwizart --- cat>/etc/modules-load.d/imx.conf<<EOF # Load ahci imx at boot ahci_platform ahci_imx EOF dracut -H /boot/initramfs-$(uname -r).img $(uname -r) mkimage -A arm -O linux -T ramdisk -C none -n $(uname -r) -d /boot/initramfs-$(uname -r).img /boot/uInitrd-$(uname -r) --- end instructions --- I indeed see that sata works at the first login prompt. However, I cannot mount the rootFS on sata, as apparently the fs mounting is done before the initialization of the AHCI (sata) subsystem. The following console output is when booting and mounting the rootFS on uSD card: ---- console output ---- Jan 1 01:00:17 localhost kernel: [ 0.000000] Booting Linux on physical CPU 0x0 Jan 1 01:00:17 localhost kernel: [ 0.000000] Initializing cgroup subsys cpuset Jan 1 01:00:17 localhost kernel: [ 0.000000] Initializing cgroup subsys cpu Jan 1 01:00:17 localhost kernel: [ 0.000000] Initializing cgroup subsys cpuacct Jan 1 01:00:17 localhost kernel: [ 0.000000] Linux version 3.12.1-2.fc21.armv7hl (mockbuild(a)arm02-builder12.arm.fedoraproject.org) (gcc version 4.8.2 20131111 (Red Hat 4.8.2-4) (GCC) ) #1 SMP Thu Nov 21 05:58:27 UTC 2013 Jan 1 01:00:17 localhost kernel: [ 0.000000] CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c5387d Jan 1 01:00:17 localhost kernel: [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache Jan 1 01:00:17 localhost kernel: [ 0.000000] Machine: Freescale i.MX6 Quad/DualLite (Device Tree), model: Wandboard i.MX6 Quad Board Jan 1 01:00:17 localhost kernel: [ 0.000000] cma: CMA: reserved 16 MiB at 3e800000 Jan 1 01:00:17 localhost kernel: [ 0.000000] Memory policy: ECC disabled, Data cache writealloc Jan 1 01:00:17 localhost kernel: [ 0.000000] PERCPU: Embedded 9 pages/cpu @c2222000 s13568 r8192 d15104 u36864 Jan 1 01:00:17 localhost kernel: [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
