ARM – Vim3-Pro – with EFI and Fedora 33..

Adventures With Linux ™ Posted on January 5, 2021 by RGJanuary 5, 2021

Recently acquired one of the Khadas VIM3-Pro arm64 SoCs, and was impressed with the level of documentation available.. Unfortunately – as is so often the case – this was all relentlessly Ubuntu-focussed, with a semi-proprietary kernel based on the 4.X kernel tree.. At least the U-Boot version was fairly recent, and appeared to support EFI etc.. The … Continue reading →

ARM – Original Hikey Updated and Fixed – with Gotchas..

Adventures With Linux ™ Posted on September 9, 2019 by RGSeptember 9, 2019

After successfully updating and re-configuring the Odroid C2 to use Fedora uefi/grub2 to boot, I decided to try to do the same to the even-older Hikey SOC. This already booted using fastboot with an older version of grub, with manual configuration, but I wanted to use the standard (Fedora) boot process. I had read that there was … Continue reading →

ARM64 – Odroid C2 – Ethernet Broken Again?

Adventures With Linux ™ Posted on December 12, 2016 by RGDecember 12, 2016

I had been trying to apply the latest round of Meson TX delay patches to the latest linux-next tree, but found that there seems to be a conflict with some of these..    The December 1 patched kernel now has some problems on my C2 with Ethernet traffic, so – for the time being – I have reverted … Continue reading →

ARM – Next CHIP ARMv7 – First Impressions..

Adventures With Linux ™ Posted on July 12, 2016 by RGJuly 12, 2016

After pre-ordering one many months ago, I finally got my Next CHIP ARMv7 system in the post.. It certainly is fairly small, but seems well-constructed..     Details are at http://docs.getchip.com/chip.html#chip-hardware After connecting the UART/USB cable, as normal, the system booted into a cut-down version of Debian..   There is no hdmi, or sdcard connector, or Ethernet, but the wi-fi … Continue reading →

ARM – Another Source for Rootfs Images..

Adventures With Linux ™ Posted on April 26, 2016 by RGApril 26, 2016

If you need a particular rootfs for an ARM7 or ARM64 device, there is a source of these at http://libguestfs.org/download/builder/ As an example, for Fedora 23 aarch64, then download the http://libguestfs.org/download/builder/fedora-23-aarch64.xz file, and then expand it (I use ark..)   This will give you a file fedora-23-aarch64, and simply rename this to fedora-23-aarch64.img. As the Fedora aarch64 images … Continue reading →

ARM – Rock2 – Fix for SDCard Boot, and Ethernet..

Adventures With Linux ™ Posted on March 19, 2016 by RGMarch 19, 2016

Kernel 4.5-rc7 had booted successfully on the Radxa Rock2, but 4.5 Final failed, as the SDcard was ‘loaded’ just too late: mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) dwmmc_rockchip ff0f0000.dwmmc: 1 slots initialized ……………………… VFS: Cannot open root device “mmcblk1p1” or unknown-block(0,0): error -6 ………………………… Kernel panic – … Continue reading →

ARM – Radxa Rock2 – Powerful, but Confused..

Adventures With Linux ™ Posted on February 24, 2016 by RGFebruary 24, 2016

Recently took delivery of a Radxa Rock2 ARMv7 system, based on the RX3288 Cortex A17 chipset.. The system comes with a version of Android installed on the onboard eMMC, but I managed – after a bit of work – to install Fedora 23 on an SDcard and get it to boot onto that..      At this point, I … Continue reading →

ARM – CuBox – Back to 4.1, and Forward to 4.3-rc1..

Adventures With Linux ™ Posted on September 18, 2015 by RGSeptember 18, 2015

I encountered more ‘network missing’ issues with Kernel 4.2 on the CuBox-i4 Pro, so reverted to Kernel 4.1.6, and all was well, again..   I have since updated to Kernel 4.3-rc1 (from kernel.org), and everything – so far – seems to be working OK.. Fedora release 22 (Twenty Two) Kernel 4.3.0-rc1 on an armv7l (ttymxc0) …………………… ]# uname … Continue reading →

ARM – CuBox to 4.2 – Carefully..

Adventures With Linux ™ Posted on September 8, 2015 by RGSeptember 8, 2015

Updated the CuBox-i4Pro to Kernel 4.2 (from kernel.org) and everything went smoothly – eventually.. I had tried using the kernel config saved from 4.1, but after booting successfully, the network suddenly stopped working after a few minutes of traffic, even though eth0 etc. was still present..     I was planning to revert to 4.1.6, but then tried creating … Continue reading →

Just updated the Qualcomm DragonBoard 410c to (patched..) Kernel 4.2-rc5, from here:  https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/shortlog/refs/heads/integration-linux-qcomlt This time, the boot was successful, and the mmc1 SDcard (rootfs) was recognised correctly..
