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 – Pi3 Still Very Unstable..

Adventures With Linux ™ Posted on June 21, 2016 by RGJune 21, 2016

I have tried the latest 4.7-next patched kernel, from https://github.com/anholt/linux/tree/bcm2837-64-next After some trials, I did manage to – just – get it to boot – after falling to an ’emergency console’, but the system is very unstable, with multiple recurring MMC errors.. ….. Give root password for maintenance (or press Control-D to continue): Error getting authority: Error … Continue reading →

ARM64 – Pi3 Success – Almost..

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

After more ‘investigation’, I managed to find a working U-Boot for a 64-bit boot of the Raspberry Pi 3, by copying it from the boot directory of this: http://www.tom-yam.or.jp/rpi3/rpi3-arm64-debian-20160414.img.xz found towards the end of the latest 64-bit thread on the Pi Forum: https://www.raspberrypi.org/forums/viewtopic.php?f=72&t=137963&sid=cd15abd8d4dd2a2d5c517f47a3e4f5e4&start=125 .  Thanks to xyinao for putting it all together..

ARM64 – Pi3 64-Bit Tribulations.. Too Soon for Stability..

Adventures With Linux ™ Posted on April 15, 2016 by RGApril 15, 2016

I had ordered a Raspberry Pi 3 back in March in the hope that it would be a useful exercise in 64-bit on a different chipset..    I was (somewhat) disappointed to find that there was no initial 64-bit support, and indeed that I had been a bit of a pioneer in even running armv7 code on my … Continue reading →

ARM – Pi2 – Kernel 4.4-rc5 – U-Boot Fail, and Workaround..

Adventures With Linux ™ Posted on December 20, 2015 by RGDecember 20, 2015

Recently attempted to update the Pi2 to Kernel 4.4-rc5, and encountered a problem.. The more recent proprietary Raspberry Pi 2 kernels have switched to using ‘DTB Overlays’ to control various components, but these are – currently – unsupported by U-Boot.. Booting the kernel with U-Boot results in mmc errors, and register dump: ……………….. timeout waiting for hardware … Continue reading →

ARM – Pi2 to 4.0 – Eventually..

Adventures With Linux ™ Posted on April 16, 2015 by RGApril 16, 2015

Finally managed to get the Raspberry Pi2 (armv7) to boot Kernel 4.0, by re-creating the kernel config from scratch, with # make bcm2709_defconfig Fedora release 21 (Twenty One) Kernel 4.0.0-v7 on an armv7l (ttyAMA0) ………… ]# uname -a Linux rgpi2 4.0.0-v7 #1 SMP PREEMPT Wed Apr 15 17:12:00 PDT 2015 armv7l armv7l armv7l GNU/Linux The ‘classic’ Pi … Continue reading →

ARM – Pi to 4.0.. Patience is a Virtue..?

Adventures With Linux ™ Posted on April 14, 2015 by RGApril 14, 2015

Tried updating the Raspberry Pi-s (Classic model B and Pi2) to Kernel 4.0, from https://github.com/raspberrypi/linux/tree/rpi-4.0.y, and my first attempt was – it seems – too soon, as the Classic Pi (armv6) failed to boot at all, and the Pi2 (armv7) only booted as far as: …………. bcm2708_dma: DMA manager at f3007000 bcm2708_gpio: bcm2708_gpio_probe 80625490 vc-mem: phys_addr:0x00000000 mem_base=0x3dc00000 … Continue reading →

ARM – Raspberry Pi and Pi2 – OK with 3.19.3..

Adventures With Linux ™ Posted on March 28, 2015 by RGMarch 28, 2015

After trials with earlier versions, the Pi and Pi2 updated to Kernel 3.19.3 without too much effort.. Source from here:  https://github.com/raspberrypi/linux/tree/rpi-3.19.y Pi: Pidora release 2014 (Raspberry Pi Fedora Remix) Kernel 3.19.3 on an armv6l (ttyAMA0) …….. ]# uname -a Linux rgpi 3.19.3 #1 PREEMPT Fri Mar 27 23:55:44 PDT 2015 armv6l armv6l armv6l GNU/Linux Pi2: Fedora release … Continue reading →

ARM – Raspberry Pi and Pi2 – Trials with Later Kernels..

Adventures With Linux ™ Posted on March 23, 2015 by RGMarch 23, 2015

I had Kernel 3.19.0 (originally from https://github.com/raspberrypi/linux/tree/rpi-3.19.y – now updated) running on my Pi (armv6) and Pi2 (armv7) with no problems (apart from the Pi2 seeming very sluggish..) but after that had a few ‘issues’.. Pi:  Kernel 3.19.1 OK, but 3.19.2 refused to boot (nothing on console) Pi2:  Kernel 3.19.1 booted and then crashed: BCM2708FB: allocated DMA … Continue reading →

ARM – Raspberry Pi ‘Classic’ – Device Tree Kernel Compile..

Adventures With Linux ™ Posted on February 22, 2015 by RGFebruary 22, 2015

After my tests compiling the new armv7 Pi 2 Kernel – with ‘device tree’ – I decided to try the same with the ‘classic’ armv6 Pi (B+).. You will need the latest version of the Pi /boot files, including the latest config.txt with the necessary parameters for device tree boot, sound config, etc.. For cross-compilation, I created … Continue reading →
