ARM64 – HiKey – Change to UEFI Boot..

Adventures With Linux ™ Posted on by

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 →

ARM64 – And Now… 8 Cores!

Adventures With Linux ™ Posted on by

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 by

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 →

ARM – ARM64 Developments…

Adventures With Linux ™ Posted on by

Just took delivery of a Qualcomm Dragonboard 410c (https://developer.qualcomm.com/hardware/dragonboard-410c) : The unit is based on a ‘standard’ (96Boards) design, with a few quirks..   The device uses fastboot rather than U-Boot, and in this respect is more like flashing a custom ROM on a cellphone!    It even has on-board volume up/down buttons.. There is no Ethernet built-in, so … Continue reading →
