Bluetooth on Udoo Neo ?
by Ken Harris 25 Jun '19

25 Jun '19

Is it possible to enable Bluetooth on Udoo Neo ? FYI, it uses the TI WL1831 module. I tried : hciattach -n ttymxc2 texas ... but got "Initialization timed out." I also tried various combinations of bit rates and flow control. Any tips are welcome. -K

Ceph (last release) on aarch64
by Pierre-Francois RENARD 23 Mar '19

23 Mar '19

Hello all, I am trying to build a ceph cluster based on 4 raspberry3B+. Following the official CEPH documentation is a dead end as packages are only available for readhat/centos and not fedora ! I tried to used the el7 repository but the are conflicts and lacks with fedora repos. Did I miss something ? I am now trying to compile from sources. it is still ongoing ( 16% after 24h !) I am considering cross compilation from a X86_64 hosts but I cannot find any recent ( and probably uptodate ) documentation, any clue on that ? Thanks Fox

how to make a working f28 sd card for odroid-hc2 ?
by Torbjorn Jansson 14 Mar '19

14 Mar '19

Hello for a while now i have been struggling to create a set of steps to make a successfully bootable fedora 28 image for my odroid hc2 computers. the reason for this is several, but main one is to have all gluster related packaged available like the samba vfs modules and iscsi related packages for gluster that is missing from the ubuntu images. plus i prefer fedora. all i get is a sd card that boots but then hangs on initial setup and if i try to work around that by disabling it then boot takes maybe 5-10 minutes at least with failing services (probably those that depend on network) and when i finally get to a login prompt root doesn't work here is my step by step instructions so far that's not quite working: (this is done from a fedora 28 host) 1: first install needed packages dnf install arm-image-installer-2.5-1.fc28.noarch dnf install uboot-images-armv7-2018.03-6.fc28.noarch 2: get image and install it to sd card fedora-arm-image-installer --target=none --image=Fedora-Minimal-armhfp-28-1.1-sda.raw.xz --resizefs --norootpass --media=/dev/sdf --args "rd.driver.pre=ledtrig-heartbeat,xhci-plat-hcd cpuidle.off=1 no_bL_switcher console=tty1 console=ttySAC2,115200n8" (sdf in this case is my sd card) 3: fix the missing dtb file mkdir /tmp/sd mount -t auto /dev/sdf2 /tmp/sd cd /tmp/sd/dtb ln -s exynos5422-odroidxu4.dtb exynos5422-odroidunknown.dtb umount /tmp/sd 4: make it boot by running sd_fusing mkdir sd_fusing; cd sd_fusing wget https://raw.githubusercontent.com/hardkernel/u-boot/odroidxu4-v2017.05/sd_f… \ https://raw.githubusercontent.com/hardkernel/u-boot/odroidxu4-v2017.05/sd_f… \ https://raw.githubusercontent.com/hardkernel/u-boot/odroidxu4-v2017.05/sd_f… \ https://raw.githubusercontent.com/hardkernel/u-boot/odroidxu4-v2017.05/sd_f… chmod a+x sd_fusing.sh cp /usr/share/uboot/odroid-xu3/u-boot.bin . ./sd_fusing.sh /dev/sdf ok so now comes the problems at this stage i have a bootable image but it gets stuck, most likely on initial setup that never shows up. the thing is, it is not locked up because if i plug in an usb device i get a few lines on the serial console so kernel is still working but boot is stuck. last few lines on serial console is something like: Starting firewalld - dynamic firewall daemon... Starting Initial Setup configuration program... then some stuff related to usb & my disk then on first boot a few lines related to OpenSSH key generation rebooting hangs at same place with exception of SSH keys. to get a bit further i can mount the root filesystem manually on my other computer and remove the following two files: rm /etc/systemd/system/graphical.target.wants/initial-setup.service rm /etc/systemd/system/multi-user.target.wants/initial-setup.service this gets rid of the initial setup but then i get a whole bunch of services failing and boot being really really slow, it takes probably 10-15 minutes for everything to time out and get to the logon prompt. when i get it root doesn't work. this is where i kind of gave up. i know i somehow managed to get a bootable image several months ago, but i'm not sure if i then had to manually set root password by editing passwd or shadow before trying to boot. things on my wish list for this board: easier installation and updated packages that work. for example arm-image-installer with a board definition for odroid. may be usefull even if we have to run sd_fusing manualy after anyway, possibly with a text saying so. this also would help to make --addconsole work uboot that recognized hc2 so it loads the right file dtb file for hc2, one that works and is appropriate.

Stable since more than around 1,5 days. Normally they have been crashed for such a long uptime. So it looks that the performance governor fixes it. I guess crashes occour because of changing CPU voltage and clock changes and invalid data (e.g. also invalid RAM contents might be read, register problems, etc). Any ideas how to fix it for ondemand mode, too?

Because the Bananas are typically really idle and crash (with the ondemand governor). Thanx. Ciao, Gerhard

Banana Pi-R1 stabil
by Gerhard Wiesinger 24 Feb '19

24 Feb '19

Hello, I've 3 Banana Pi R1, one running with self compiled kernel 4.7.4-200.BPiR1.fc24.armv7hl and old Fedora 25 which is VERY STABLE, the 2 others are running with Fedora 29 latest, kernel 4.20.10-200.fc29.armv7hl. I tried a lot of kernels between of around 4.11 (kernel-4.11.10-200.fc25.armv7hl) until 4.20.10 but all had crashes without any output on the serial console or kernel panics after a short time of period (minutes, hours, max. days) Latest known working and stable self compiled kernel: kernel 4.7.4-200.BPiR1.fc24.armv7hl: https://www.wiesinger.com/opensource/fedora/kernel/BananaPi-R1/ With 4.8.x the DSA b53 switch infrastructure has been introduced which didn't work (until ca8931948344c485569b04821d1f6bcebccd376b and kernel 4.18.x): https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drive… https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/driver… https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/dri… I has been fixed with kernel 4.18.x: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/driver… So current status is, that kernel crashes regularly, see some samples below. It is typically a "Unable to handle kernel paging request at virtual addres" Another interesting thing: A Banana Pro works well (which has also an Allwinner A20 in the same revision) running same Fedora 29 and latest kernels (e.g. kernel 4.20.10-200.fc29.armv7hl.). Since it happens on 2 different devices and with different power supplies (all with enough power) and also the same type which works well on the working old kernel) a hardware issue is very unlikely. I guess it has something to do with virtual memory. Any ideas? Thanx.
