Odd problem with kernel 3.6-rc3 on the Dreamplug… I had the usual /etc/fstab entry, with both the ext4 root and vfat boot devices configured, but now – despite LVM / RAID not being enabled in the kernel, the init/systemd process insisted on treating the vfat device as a LVM/RAID device, and failing, and dropping to the ’emergency’ … Continue reading →
After all the fuss with ancient versions of Linux on the APC, I now have the very latest Linux – 3.6-rc3 – running on the Dreamplug..: Fedora release 17 (Beefy Miracle) Kernel 3.6.0-rc3 on an armv5tel (ttyS0) rgdreamplug login: …………. # uname -a Linux rgdreamplug 3.6.0-rc3 #1 Fri Aug 24 00:20:25 BST 2012 armv5tel armv5tel armv5tel GNU/Linux … Continue reading →
The ‘default’ Fedora 13 system for ARM mounts the root as nfs.. To change it to the (correct) ext3, modify /etc/fstab as follows: # cat /etc/fstab /dev/mmcblk0p2 / ext3 defaults 1 1 /dev/mmcblk0p1 /boot vfat defaults 1 0 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 proc /proc proc defaults 0 0 sysfs … Continue reading →
For Fedora 13 on the APC, the console on the usb/uart connection will ‘vanish’ on boot, after ………. Starting sshd: [ OK ] To get it back, and allow login as root, add the following to /etc/securetty: ttyS0 and modify /etc/sysconfig/init: from ACTIVE_CONSOLES=/dev/tty[1-6] to ACTIVE_CONSOLES=”/dev/tty[1-6] dev/ttyS0″ To stop the (re)login prompt from appearing over the console boot … Continue reading →
In a vain attempt to get the APC’s antique kernel to – at least – work with Fedora 14, I had been applying the series of ‘incremental’ 2.6.32.x patches available – amongst other places – at http://ftp.monash.edu.au/pub/linux/kernel/v2.6/incr/ The kernel.org ftp site didn’t seem to have the full set.. This brought me as far as 2.6.32.27, which still … Continue reading →
In the hope of getting a newer version of Fedora Linux running, I have ‘updated’ the 2.6.32.9 APC kernel to 2.6.32.27.. This was achieved by the labour-intensive method of applying all the incremental kernel patches in sequence, and manually fixing any code that ‘failed’ the patch… So.. I am now running Fedora 13 with kernel 2.6.32.27 on … Continue reading →
As the currently-available source for the APC kernel does not include the necessary drivers for video output to a monitor (amongst other things..) but does include network drivers (Via Velocity..) it seemed logical that I could adopt the same approach to a graphical interface that I use for the Dreamplug (which is a real ‘headless’ device!). So.. … Continue reading →
After all the pioneering work done to get a compiled working version of the APC kernel by Mike Thompson from the Raspbian project, as described in a previous post, I now have Fedora Linux running on the APC. I had planned to be able to get Fedora 17 working, but the APC kernel (vintage 2010!) is just … Continue reading →
After excellent work done by Mike Thompson from the Raspbian project, there is now a set of patches and a config file available for the APC-supplied 2.6.32.9+ kernel source, which enables a working kernel to be compiled and run – although with limited functionality due to ‘missing’ device drivers.. More details at : http://www.raspbian.org/ApricotImages To use this, … Continue reading →
Just to finally confirm that the U-Boot parameters were not in any way affection the APC boot – and therefore that the problem was in the APC’s kernel configuration, probably with the CONFIG_CMDLINE parameter in the original kernel’s .config file – I removed all the U-Boot parameters, as follows: WMT # setenv wmt.display.logoaddr; setenv logocmd; setenv wmt.gpo.lcd; … Continue reading →
