I discovered there was a later version (6) of the U-boot patch for the Odroid C2, and also – after more research – found the reason for the compile error… It turns out that the GIT version (May 5, 2016) of U-boot currently needs two patches.. The first one is to provide psci_system_reset for armv8, and details … Continue reading →
Kernel 4.6-rc6 has been released, and details of changes since -rc5 are here: http://lkml.iu.edu/hypermail/linux/kernel/1605.0/00190.html It seems that there will be (at least..) an rc7, before ‘Final’.. Tested with patched VMware 12.1.0 (vmnet and vmmon) and patched NVIDIA (364.19) and both still compile OK.. See my previous article https://rglinuxtech.com/?p=1709 for more info.. Robert Gadsdon. May 2, 2016.
Continue reading →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 https://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: https://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 →
