ARM64 – Pi4 – Finally, a fix for the USB Issues..

Adventures With Linux ™ Posted on September 3, 2021 by RGSeptember 3, 2021

I had spent far too much time trying to solve the Pi4 USB conundrum ( see https://rglinuxtech.com/?p=2922 ) but did recently find that the 5.14-rc kernels enabled the USB3 hub, although USB2 still failed to function.    I then updated u-boot to the ‘latest’ version, and now everything (finally..) works as it should, again..: Updated u-boot to latest … Continue reading →

ARM64 – Pi 4 USB Problems – And a Messy Fix..

Adventures With Linux ™ Posted on May 11, 2021 by RGMay 11, 2021

After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →

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 →

ARM64 – Fedora 33 Pre-release Kernel Boot Problem – and Workaround..

Adventures With Linux ™ Posted on August 26, 2020 by RGAugust 26, 2020

I have been testing Fedora 33 pre-release, and on x86_64 it seems relatively stable (usual caveats…) but on arm64 systems (Odroid N2 and Pi4) I found that after compiling a new kernel (5.8.3), the system booted, but login was impossible, and screen output was missing  (uart/console was OK). Kernels compiled with Fedora 32 all booted OK, and … Continue reading →

ARM64 – 8GB Pi4 – Fun with Fedora..

Adventures With Linux ™ Posted on July 18, 2020 by RGJuly 18, 2020

My 8GB Raspbery Pi 4 finally arrived, and I was looking forward to trying Fedora 32 and KDE/Plasma on it, and comparing it to the Odroid N2 from a few months back.. ( http://rglinuxtech.com/?p=2689 ) The Fedora 32 aarch64 install is supposed to support the Pi 4 now, but the resulting sdcard image failed to boot, with … Continue reading →

ARM64 – Odroid N2 – Latest U-Boot, Kernel 5.6-rc2, EFI, Fedora 31, Plasma/Wayland

Adventures With Linux ™ Posted on February 17, 2020 by RGFebruary 17, 2020

I have recently acquired an Odroid N2 (4GB) and managed – with some difficulty – to get it to run a ‘modern’ U-Boot, Kernel 5.6-rc2, with EFI support, and Fedora 31. This time, there were no clues from OpenSuse, and all the examples I found still used the ancient/custom Hardkernel u-boot and a kernel.img ‘blob. Fortunately, the … Continue reading →

ARM64 – Fedora 27, UEFI and Pi3..

Adventures With Linux ™ Posted on December 12, 2017 by RGDecember 12, 2017

I decided – after some time – to do some more with the Raspberry Pi 3, and set it up as a small network print server.. As there was now an ‘official’ version of Fedora 27 for the Pi3, I decided to use this..   Details are here, and links to aarch64 images are near the bottom of … Continue reading →

ARM64 – 4.14-rc1 Problems..?

Adventures With Linux ™ Posted on September 18, 2017 by RGSeptember 18, 2017

Kernel 4.14-rc1 has been stable on the x86_64 test system, but when I tried updating the Odroid C2 (ARM64) I saw a lot of mmc and other errors reported.. ………. [ OK ] Started File System Check on Root Device. Starting Remount Root and Kernel File Systems… mmcblk0: response CRC error sending r/w cmd command, card status … Continue reading →

ARM64 – Odroid C2 – Patches for USB..

Adventures With Linux ™ Posted on January 18, 2017 by RGJanuary 18, 2017

Thanks to Heiner Kallweit for info on two USB patches for the Odroid C2, and thanks to John Youn for the patches themselves..  They can be found at http://www.spinics.net/lists/linux-usb/msg151687.html and http://www.spinics.net/lists/linux-usb/msg151688.html . I have applied these to Kernel 4.10-rc4 (including the Ethernet TX patch) and now USB is working, and detects/connects devices – sort of.. Plug in … Continue reading →

ARM64 – Kernel 4.10-rc4 on Odroid C2 – Ethernet Still Needs DTS Patch..

Adventures With Linux ™ Posted on January 17, 2017 by RGJanuary 22, 2017

Just updated the Odroid C2 to Kernel 4.10-rc4, but the Ethernet hang problem still persists..   Applied the dts Ethernet TX patch (see http://rglinuxtech.com/?p=1872 ) , and it works OK now.. There seems to be a bit of a backlog of Meson/GXBB patches, and I read that the Ethernet TX fix was supposed to be merged with -rc4, … Continue reading →
