CI20 - MIPS dev. board - first impressions.

Annoyingly, I've bought one of these just before the form factor changes and it becomes a nice square board.

Up and running immediately out of the box, which is nice.

The kernel supplied on NAND flash is recent enough that it supports CONFIG_FHANDLE which is needed for the upgrade to Jessie.

The instructions for Jessie upgrade are straightforward and appear to be working correctly: they also suggest apt-get autoremove and apt-get autoclean to clean up which is a very nice touch.

The sources.list in apt was already pointing to my country's Debian mirror which was even nicer.

Quite a good experience immediately from unboxing: it also adds to the number of machine architectures I've run Debian on:
alpha, amd64, arm, armel, armhf, i386, sparc - not bad for a start.

It's a bit slow - but it's a SoC, so what can you expect? The PowerVR graphics demos were spectacular  but the drivers are very definitely non-free - you can't have everything.

[I do notice that there is an FSF-friendly Debian variant, though not yet certified as such - presumably not including PowerVR drivers]

(Lots of occurrences of the word "nice" in this post that I've just noticed. It's either understatement or just that I'm British)

Jessie - very nearly released as I write :) :)

I've spent a chunk of the day testing installs of Jessie on various hardware I have here.

About 8 AMD64 installs later, I've almost done testing many of the variants.

One i586 install done - that's a really old laptop :)

I'm about to re-install the Cubietruck to test an armhf install :)

It's been a really long day - but we're almost there for the final mirror push :)

This is what it's all about - time on IRC, lots of work, lots of fellow feeling: it may only be once every couple of years, but the value is immense.

Windows 8.1 / Debian 8 dual boot on Lenovo laptop

Just proved this to be feasible on a new SSD. This was done using Windows bootable media and a Jessie netinst. The Debian netinst was copied onto a USB stick.

1. Switch  Secure Boot to "off" in BIOS / system settings

2. Set machine to UEFI boot.

3. Install Windows 8.1 to first part of the disk in a custom install. On a 128GB disk, I gave Windows 8.1 30GB.

4. Install Jessie from USB: allow Grub efi to install.

It does work and was a useful demonstration for a friend.

Cubietruck now running Debian :)

Following a debootstrap build of sid on one machine to complete the cross-compilation of mainline u-boot, I managed to get vanilla Debian installed on my Cubietruck

A USB-serial cable is a must for the install and for any subsequent major reconfiguration as the stock Debian installer does not have drivers for the video / audio. Various Cubietruck derivative distributions do - but the Sunxi kernel appears flaky

All was fine for a few days, then I decided to try and configure the Wifi by hand configuring /etc/network/interfaces and wpasupplicant files. I managed to break the network connectivity by doing things in a hurry and typing blind. I'd put it into the appropriate closed metal case so was rather stuck.

A friend carefully took the case apart by easing off the metal cover plates, removed two screws holding the whole thing together and precision drilled  the metal cover plates on one side so that four screws can be undone and the entire inner part of the case can slide out as one while the other metal clover plate remains captive. He will follow this procedure with his two later.

Very pleased with the way it's turned out. The WiFi driver has non-free firmware but I now have a tiny, silent machine, drawing about 3W tops and both interfaces are now working.

Formal key transitiion to 4096 bit key

Following mini-Debconf and submitting my key to keyring-maint, here's a copy of the note marking the transition. I do retain a copy of the old key: it has not been compromised or revoked (until I'm sure my new key reaches the Debian keyring) and my vote in the GR is validly signed with the old key.

This is intended to replace the old key by the new key as part of a key transition from old, insecure keys

All the best,

Still at the mini-Debconf in Cambridge

Lots of talks, hopefully being live streamed.

Lots of side chats going on - also a room full of folk typing on laptops while lectures are going on - multi-tasking, as ever.

New ideas bouncing around as people see interesting possibilities - all good fun, as ever.

At mini-Debconf Cambridge:

Much unintentional chaos and hilarity and world class problem solving yesterday.

A routine upgrade from Wheezy - Jessie died horribly on my laptop when UEFI variable space filled, leaving No Operating System on screen.

Cue much running around: Chris Boot, Colin Walters, Steve dug around, booted the system usng rescue CD and so on. Lots more digging, including helpful posts by mjg59 - a BIOS update may solve the problem.

Flashing BIOS did clear the variables and variable space and it all worked perfectly thereafter. This had the potential for turning the laptop into a brick under UEFI (but still working under legacy boot).

As it is, it all worked perfectly - but where else would you get _the_ Grub maintainer, 2 x UEFI experts and a broken laptop all in the same room ?

If it hadn't happened yesterday, it would have happened at home and I'd have been left with nothing. As it is, we all learnt/remembered stuff and had a useful time fixing it.
