ARM64 – HiKey – Change to UEFI Boot..

Adventures With Linux ™ Posted on July 22, 2015 by RGJuly 22, 2015

After some more testing, including trying (unsuccessfully) the HiKey version of Kernel 4.1-rc4 # git clone -b hikey-mainline-rebase –single-branch https://github.com/96boards/linux/   I was frustrated by the complete lack of kernel boot info on screen, after the proprietary bootloader had finished.. More research found that this bootloader was described as somewhat deficient in the ‘fit for purpose’ department, and … Continue reading →

ARM – Pi2 to U-Boot..

Adventures With Linux ™ Posted on July 16, 2015 by RGJuly 16, 2015

I decided to try U-Boot on the Raspberry Pi 2, and the process has been fairly well documented in several places.. I used the latest U-Boot, with ‘patch’ info from here, as I needed Device Tree support:  https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=108217. Actual ‘installation’ is simple, as I just copied the u-boot binary to the boot directory on the SD Card, … Continue reading →

ARM64 – HiKey With Proper UART Connection..

Adventures With Linux ™ Posted on July 12, 2015 by RGJuly 12, 2015

One of the most annoying missing features of the HiKey ARM54 board is the lack of a proper UART connection, to enable the same degree of boot information as other SoC systems..     There is a 4-pin/hole connection point, but no actual connector…    So, I had to get out the (mini) soldering iron, and magnifying goggles, and use … Continue reading →

ARM64 – And Now… 8 Cores!

Adventures With Linux ™ Posted on July 9, 2015 by RGJuly 9, 2015

I had another ARM64 system on order for some time, and – unexpectedly – it shipped a few days ago.. It is an 8-core ‘Hikey’ board, based on the same 96Boards outline as the DragonBoard 410c.. So far, I have it booting – with the Linaro/Hikey 3.18 kernel – and have put Fedora 22 on it.. Fedora … Continue reading →

ARM64 – DragonBoard 410c to Kernel 4.1..

Adventures With Linux ™ Posted on July 2, 2015 by RGJuly 2, 2015

Managed to update the DragonBoard 410c to Linaro Kernel 4.1.0+, from here: git clone https://git.linaro.org/landing-teams/working/qualcomm/kernel.git -b integration-linux-qcomlt So far, I have made the kernel ‘monolithic’ with all necessary modules built-in (‘y” instead of ‘m’), as this was how the original Linaro/Qualcomm kernel was built..     As the 410c uses the android fastboot, it would seem that the kernel/boot … Continue reading →
