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 →
Updated the DragonBoard 410c to patched Kernel 4.2-rc1 from https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/tree/refs/heads/integration-linux-qcomlt , and the system booted OK: Fedora release 22 (Twenty Two) Kernel 4.2.0-rc1+ on an aarch64 (ttyMSM0) ……….. # uname -a Linux rg410c 4.2.0-rc1+ #2 SMP PREEMPT Thu Jul 16 15:14:27 PDT 2015 aarch64 aarch64 aarch64 GNU/Linux – But, on further testing, the SD Card (mmc1) had … Continue reading →
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 →
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 →
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 →
Update: Same results with 4.2-rc3.. (RG July 19) Update: Kernel 4.2-rc2 fails with VMware (vmnet) and NVIDIA in the same ways.. (RG July 14) Updated to kernel 4.2-rc1 on the test system: # uname -a Linux rg6830l 4.2.0-rc1 #1 SMP Sun Jul 5 18:36:06 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux Brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1507.0/02156.html VMware 11.1.2 … Continue reading →
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 →
