Marshmallow Is Alive

Today, Xperia Tablet Z booted into CyanogenMod 13 for the first time. Many things still broken, but it is a start!

Lollipop Fusion Complete

As of today, all Sony Xperia devices based on the Fusion3 board (Xperia Z, ZL, ZR, Tablet Z, Tablet Z WiFi) are getting official CyanogenMod 12.1! When I first started looking at these devices in December 2014, the CM12 source code would not even compile, let alone boot, and even the recovery was broken. Well, …

Carpe Noctem #2

After a long, arduous development road, I’ve enabled CyanogenMod nightly builds for the Sony Xperia Z. This brings nightlies directly from CM11 to CM12.1, which hopefully all users will enjoy. Thanks to everyone at my XDA thread, especially Andy van der Steen, who lent me his phone for development. Without that, I would never have …

Tests have shown it to outperform the default ext2/3/4 that we used previously, so definitely a nice thing to have. However, if you want to benefit from F2FS, you need to …

CyanogenMod Fusion

In January, I’ve been added as a device maintainer for Sony’s fusion3 platform on CyanogenMod. That platform includes the original Xperia Z line of devices (Z, ZL, ZR, Tablet Z, Tablet Z Wifi). Most of my work went into the platform and the 2 tablets, since I actually own one of these. By now, I …

Smart phone RIL

After tinkering with cameras and solar power systems, it was time to play around a bit with Android – in the form of CyanogenMod. After setting up a build environment for my i9100 (a Galaxy S2 in marketing terms), I decided to help figure out a problem with open-sourcifying one of the libraries for it, …

Today, the updated CHDK code for IXUS 970 has been uploaded to the project’s official source code repository. This new version fixes a problem with the detection of the play mode, and most prominently adds support for firmware revision F, so now all dumped revisions are covered. The firmware addon can be downloaded at the …

Another piece of contract work completed: this one involved solar power panels and inverters from Austrian manufacturer Fronius. Developed a generic, object oriented data fetching backend and set it up to transmit the data to a database over a HTTP tunnel. One visible outcome of the project can be found here: VS Seeham. Enjoyed working …
