While work on the kernel steadily progresses, there’s quite a few bits and pieces that finally fall into place. Here’s a list of all devices on the Nexus 7 that are hooked up via i2c. I’m currently working on getting the basics, such as charging and battery to work. The Summit Microelectronics SMB345 seems to… Read More »
And we’re marching on. Here’s a little recap of my Nexus 7 kernel development efforts so far.
Okay – I admit it. I’ve been absent for far too long. Would you beliee me if I told you, I had *erm* reasons? Yeah, didn’t think so 😀 Alright, so – my lazy ass was exactly that: lazy. This morning, I just couldn’t stand the Nexus’ puppy-eyes and got cracking a bit. Before I… Read More »
This might come in handy one day. I raided the DebugFS on the Nexus 7 and tried to cross-reference it with the Kernel-Source for GPIO pin-assignments and tried to match them to a module / functionality.

In retrospective, it was rather straightforward, once I figured out just how paranoid Android devices can be. Since there’s still no news of my last batch of hardware-tools, I poked around the (rooted) stock android some more. Feel bored? Have a little dmesg
Some infos about the Nexus 7 input devices I managed to grab from the stock-android’s dmesg and the kernel-sources
