Note: as @clibois mentioned below, due to the DRM Netflix uses, all decoding has to be done in CPU, making it somewhat choppy.

Note 2: Even the RPi 3 suffers from these CPU limitations. There is the potentially risky option of overclocking your RPi 3, but I haven't tried this.

If you manage to get smooth playback, please contact me, or post your solution here

UPDATE: I can no longer get this method to work. I have tried using Chromium v47, and v48, and both result in Netflix error "Oops, something went wrong" / C7053-1807, for which I can find no description online. If you manage to get things up and running, please contact me!

The new Raspberry Pi 3 released on 29 Feb 2016 has issues with its UART port as the pinout GPIO 14/15 on the pin header is now based on a low throughput mini-UART.

To understand the issue better than reading the wall of text below, you can see the talk I gave on this issue.

The actual hardware UART on the BCM2837 SoC has now been assigned to handle Bluetooth with the BCM43438 Wifi/Bluetooth chip. More details can be found here and here.

This mini-UART does not produce a stable baud rate as it fluctuates based on the Core clock speed whenever it rises or falls. The result is that the serial debug output is practically unusable. On Raspbian you may see garbage or nothing at all. The solution is simple, add core_freq=250 to /boot/config.txt to cap the core frequency to a constant value. This optio

I wanted Octoprint (a 3D-printer management software) to start up fast without the bloatness of using Raspbian. I also regularly forgot to shutdown the Raspberry Pi hosting Octoprint properly leading to file system corruption and unbootable SD card.

This set of instructions should provide all that is needed to use Octoprint without fear of improper shutdown with Arch Linux ARM by using a read-only file system.

This instructions does not have the webcam setup as I didn't intend to use it. If you wish to use the webcam, please consult and try to port the official Raspbian FAQ.

##Instructions

Convert the Arch Linux ARM file system to read-only. Please follow the instructions from my previous gist. The following instructions assume you are logged into with the root account.

##Read-only FS on Arch Linux ARM

Unlike your typical computer where you usually shutdown properly, I cannot rely on this during the use of my Raspberry Pi. If the Raspberry Pi is improperly shutdown too many times, data corruption in the file system leading to unbootable SD card may result. So we should use a read-only file system.

Full instructions and explanations are obtained from this link but you can run these commands directly. I modified some of the instructions for personal convenience.

Login with default username: alarm, password: alarm

#Optionally enable root over SSH. The rest of these instructions assume u are in root.

Intro

Just some FYI, to get started:

I'm using a 16 GB Sandisk SD card.
I have a model B Pi, 512 MB RAM (not really relevant, thought I'd mention it).
Monitor and keyboard connected to the Pi itself, for now.
Network working, internet access.
