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 →
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 .

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..

Kernel 4.5-rc7 had booted successfully on the Radxa Rock2, but 4.5 Final failed, as the SDcard was ‘loaded’ just too late: mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) dwmmc_rockchip ff0f0000.dwmmc: 1 slots initialized ……………………… VFS: Cannot open root device “mmcblk1p1” or unknown-block(0,0): error -6 ………………………… Kernel panic – … Continue reading →
After a lot of testing, and some more confusion, I have managed to get the Rock2 to boot using the latest (2016.03-rc3) version of U-Boot, and the latest kernel (4.5-rc7) As previously, there was a lot of conflicting information……. I started by booting into the semi-proprietary 3.10-based kernel on the SDcard, and then erasing the eMMC (dd … Continue reading →
I have just posted copies of recent kernel configs for the Odroid U3 and CuBox-i4Pro..
