Examining the (considerable) changes in ARM support in kernel 3.7-rc1, and the first bits for support of the Raspberry Pi’s Broadcom BCM2835 CPU are there! Not usable yet, as there is very limited functionality, and the rest of the SoC (System on a Chip) features are not yet there, but it is a start, and will ensure … Continue reading →
I have managed to update the Dreamplug to kernel 3.7-rc1, after a simple fix, to get it to compile OK.. The original (cross)compile failed, with: ERROR: “read_current_timer” [drivers/video/udlfb.ko] undefined! ERROR: “read_current_timer” [crypto/tcrypt.ko] undefined! Fix, is to change ../linux-3.7-rc1/arch/arm/kernel/armksyms.c, at line 51, as follows: From: /* platform dependent support */ EXPORT_SYMBOL(arm_delay_ops); To: /* platform dependent support */ … Continue reading →
I now have the Raspberry Pi running on kernel 3.6.1-pi, recently downloaded from GitHub, as per my earlier post.. Fedora release 17 (Beefy Miracle) Kernel 3.6.1-pi on an armv6l (ttyAMA0) …….. $ uname -a Linux rgpi 3.6.1-pi #4 Mon Oct 15 13:08:24 BST 2012 armv6l armv6l armv6l GNU/Linux FYI, the download link on GitHub was still pointing … Continue reading →
Just checked the Raspberry Pi GitHub repository, and there is a ‘3.6.y’ kernel there, now.. https://github.com/raspberrypi/linux/tree/rpi-3.6.y Will download and see if it compiles and installs, yet.. It might just be a first attempt to patch to 3.6, though… This is – of course – a welcome development, to keep the Pi kernel up-to-date..

Fedora release 17 (Beefy Miracle) Kernel 3.6.1 on an armv5tel (ttyS0) $ uname -a Linux rgdreamplug 3.6.1 #1 Thu Oct 11 15:25:25 BST 2012 armv5tel armv5tel armv5tel GNU/Linux In case anyone needs it, the kernel .config I used is at http://pastebin.com/2wUCv0yA This is a test config, and contains a lot … Continue reading →
Just updated the Dreamplug to kernel version 3.6-rc7, and nothing broke.. Fedora release 17 (Beefy Miracle) Kernel 3.6.0-rc7 on an armv5tel (ttyS0) # uname -a Linux rgdreamplug 3.6.0-rc7 #1 Mon Sep 24 20:34:13 BST 2012 armv5tel armv5tel armv5tel GNU/Linux Sadly, this is the only ‘up-to-date’ ARM device I have, as the Raspberry Pi is on 3.2.27 – … Continue reading →
The availability of additional kernel code – and functionality – is good news, but the APC kernel version is still a relative antique.. 2.6.32.9 is over 2 years old, now, and the latest ‘mainstream’ Linux kernel is 3.5.4, and 3.6 will soon be released… Assuming the focus is still on Android, then an update to Android 4.1 … Continue reading →
Well, the ‘Turbo’ Pi overclocking might be great for playing games (Quake 3, anyone?) but regular apps don’t like it. After applying the Turbo 1GHz overclock, I immediately had problems with yum / rpm segfaulting when run, so reverted to the standard 700MHz again, and all is well.. Maybe a little less overclock, might be more stable?
Continue reading →The recent announcement regarding ‘overclocking’ the Raspberry Pi was too good to ignore: http://www.raspberrypi.org/archives/2008 So, as most Pi stuff seems to be Debian-centric these days, this is how I did it for Fedora… This method should also work for any other distro.. You will need to compile and install the latest version of the Pi 3.2.27 kernel … Continue reading →
I have just updated the Raspberry Pi to kernel 3.2.29, from the latest Pi kernel 3.2.27 at https://github.com/raspberrypi/linux, plus the two incremental patches from ftp://ftp.kernel.org/pub/linux/kernel/v3.0/incr/ The system is OK, and USB seems to be more stable than before, even after plugging in USB1.1 devices.. Fedora release 17 (Beefy Miracle) Kernel 3.2.29-pi on an armv6l (ttyAMA0) ………. usb … Continue reading →
