ARM – Pi2 to U-Boot..

Adventures With Linux ™ Posted on by

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 by

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 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 →

After quite a lot of messing about, I got Fedora 22 running on the ARM64 DragonBoard 410c: Fedora release 22 (Twenty Two) Kernel 4.0.0-linaro-lt-qcom on an aarch64 (ttyMSM0) ………… $ uname -a Linux rg410c rg410c.almaden 4.0.0-linaro-lt-qcom #1 SMP PREEMPT Fri Jun 5 15:17:06 UTC 2015 aarch64 aarch64 aarch64 GNU/Linux Still running the ‘stock’ Linaro/Qualcom version of Kernel … 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 →
