Just updated the Qualcomm DragonBoard 410c to Linaro/Qcom patched Kernel 4.2, from here: https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/tree/refs/heads/integration-linux-qcomlt
Using the saved kernel config from 4.2-rc5, the system booted OK (headless)..:
Fedora release 23 (Twenty Three) Kernel 4.2.0 on an aarch64 (ttyMSM0) ................ # uname -a Linux rg410c 4.2.0 #1 SMP PREEMPT Sun Sep 13 20:13:35 PDT 2015 aarch64 aarch64 aarch64 GNU/Linux
Although the 410c is still in many ways like a ‘phone that boots Linux’ (having to use fastboot to update the kernel, and using a ‘volume-up’ button on the board), at least the kernel devs are keeping reasonably up-to-date, unlike the sorry state of HiKey kernel development, which still seems to be stuck with a heavily patched version of an ancient 3.18 kernel..
