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 →
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 →
Updated the CuBox i4-Pro and Raspberry Pi to Kernel 3.16 recently, using the kernel source from.. Raspberry Pi: https://github.com/raspberrypi/linux/tree/rpi-3.16.y CuBox i4-Pro: https://github.com/jmontleon/fedora-20-cubox-i_hb/tree/3.16.0 Fedora release 20 (Heisenbug) Kernel 3.16.0 on an armv7l (ttymxc0) …………… # uname -a Linux rgcubox 3.16.0 #1 SMP PREEMPT Mon Aug 4 23:39:27 EDT 2014 armv7l armv7l armv7l GNU/Linux Pidora release 2014 (Raspberry Pi … Continue reading →
I originally wrote an article on cross-compiling for ARM systems, some time ago – before I got my first Raspberry Pi – and this is a more up-to-date version. This is how I cross-compile ARM kernels, on x86_64. There are – of course – other ways of doing this, but this works, for me.. The following info … Continue reading →
Updated the Dreamplug to 3.7-rc2 today, and still needed to patch ../linux-3.7-rc2/arch/arm/kernel/armksyms.c, as described in the post for 3.7-rc1.. Fedora release 17 (Beefy Miracle) Kernel 3.7.0-rc2 on an armv5tel (ttyS0) …………………. $ uname -a Linux rgdreamplug 3.7.0-rc2 #2 Sun Oct 21 14:13:41 BST 2012 armv5tel armv5tel armv5tel GNU/Linux … Continue reading →
As my APCs are being held to ransom, until I get an invoice for UK customs duty and taxes (by post!!) and am then able to pay it (online?).. I decided to add another flavour of cross-compiler to the ones I already have installed. This one comes from the self-contained OpenELEC environment which is used to create … Continue reading →
As the APCs are still ‘awaiting customs clearance’, I decided to try to cross-compile the kernel source available at github: https://github.com/apc-io/apc-8750 Unfortunately, many of the APC-specific drivers (‘wmt’) are currently missing.. The system is an Android 2.3 one, and the kernel is based – as you would expect – on Linux kernel version 2.6.32. (In this case … Continue reading →
I was becoming a little concerned that the Raspberry Pi kernel was getting left behind – at 3.1.9+ (now an EOL – End Of Life – version). So, I found the 3.2.21 source produced by bootc, at https://github.com/bootc/linux/tree/rpi-3.2.21 Compiled OK, using the ARM cross-compilation toolchain, and now running with Fedora 17: rgpi ~]$ uname -a Linux rgpi … Continue reading →
I had noticed that the OpenELEC XBMC build for the Raspberry Pi included a 3.1.10 kernel, so decided to ‘update’ my Fedora 17 card to this, using the OpenELEC kernel source, cross-compiled.. So.. Now running Fedora 17 on a 3.1.10 kernel: $ uname -a Linux rgpi 3.1.10 #1 Tue May 8 13:41:06 BST 2012 armv6l armv6l armv6l … Continue reading →
The Fedora armv5tel / x86_64 cross-compiler toolchain is a bit ancient (GCC 4.1.2!), and the Pi is armv6.. So.. I needed a more up-to-date and architecture-friendly substitute.. After some abortive attempts (some of the other armv7 cross-compilers were just as old!) I found a set of armv7 / x86_64 cross-compiler rpms – including gcc version 4.6.1 – … Continue reading →
