I decided to check the latest linux-next tree for signs of Odroid C2 code, and there is some there – apparently for basic functionality.. Compiled OK, but when I tried to boot it, the Hardkernel-supplied version of U-Boot crashed: odroidc2#ext4load mmc 0:1 ${loadaddr} /boot/uboot/Image 7748608 bytes read in 187 ms (39.5 MiB/s) odroidc2#ext4load mmc 0:1 ${dtb_loadaddr} /boot/uboot/meson-gxbb-odroidc2.dtb … Continue reading →
If you need a particular rootfs for an ARM7 or ARM64 device, there is a source of these at http://libguestfs.org/download/builder/ As an example, for Fedora 23 aarch64, then download the http://libguestfs.org/download/builder/fedora-23-aarch64.xz file, and then expand it (I use ark..) This will give you a file fedora-23-aarch64, and simply rename this to fedora-23-aarch64.img. As the Fedora aarch64 images … Continue reading →
After more ‘investigation’, I managed to find a working U-Boot for a 64-bit boot of the Raspberry Pi 3, by copying it from the boot directory of this: http://www.tom-yam.or.jp/rpi3/rpi3-arm64-debian-20160414.img.xz found towards the end of the latest 64-bit thread on the Pi Forum: https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=137963&sid=cd15abd8d4dd2a2d5c517f47a3e4f5e4&start=125 . Thanks to xyinao for putting it all together.. I copied the kernel Image … Continue reading →
Kernel 4.6-rc5 is out, and brief details of changes from -rc4 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.3/00178.html Kernel 4.6 seems to have a habit of continuing later-rc breakages with VMware and NVIDIA, compared to previous kernel releases.. The VMware 12 fix for 4.6-rc4 (see http://rglinuxtech.com/?p=1706 ) still works OK with 4.6-rc5, but even the latest NVIDIA driver – 364.19 breaks … Continue reading →
Thanks to Justin Palermo, there is a patch for VMware 12 vmmon and vmnet problems he identified with the later Kernel 4.6-rcs. See comments on my earlier 4.6-rc1 article for details: http://rglinuxtech.com/?p=1679 I have applied the patch to VMware 12.1.0, on Kernel 4.6-rc4, and VMware now compiles and runs OK.. Robert Gadsdon. April 22, 2016. … Continue reading →
I had been running Kernel 4.6-rc2 on the Radxa Rock2 without any issues, and decided to update to recently-released Kernel 4.6-rc4.. Brief details of changes from -rc3 are here: http://lkml.iu.edu/hypermail/linux/kernel/1604.2/00610.html The boot failed, and I then compiled/installed 4.6-rc3 to see if that would have been OK, and it was.. I then noticed something odd in the failed … Continue reading →
Being the pioneer/masochist type (aka ‘early-adopter’..), I was intrigued by the new Intel Atom x5-Z8350-powered UP Board, and now have one on (pre)order.. Basic info, with too much graphics.. http://www.up-board.org/specifications/ Not much info on their forum, yet, but it does have UEFI, so (speculation!) should boot with good old GRUB.. One thing it does not have is … Continue reading →
I had ordered a Raspberry Pi 3 back in March in the hope that it would be a useful exercise in 64-bit on a different chipset.. I was (somewhat) disappointed to find that there was no initial 64-bit support, and indeed that I had been a bit of a pioneer in even running armv7 code on my … Continue reading →
I recently acquired on of the rather quirky Geekbox ARM64 devices, together with the oddly-named ‘Landingstrip’ expansion board.. http://www.cnx-software.com/2015/11/19/geekbox-is-a-hackable-android-and-linux-tv-box-powered-by-rockchip-rk3368-soc/ http://forum.geekbox.tv/ The similarity in overall design to the ARMv7 Radxa Rock2 will be seen from the photo: If you are ordering one, it is worth getting the USB/UART connector as well, as the 3-pin micro flat-pin connection is … Continue reading →
Updated the Rock2 to Kernel 4.6-rc2, and the Ethernet problem has been fixed..
