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

Arch Linux btrfs install

NOTE: Last update to this gist was on Jun 2, 2018. Most of the things here are out of date (e.g consider using zstd for transparent compression instead of lzo), so do your own research as well. Take care!

0. Prerequisites

• Plenty of storage - snapshots will take (sort of) a lot of space
• Latest Arch Linux install iso because those have newer kernels and more bugfixes in btrfs.
• Have previous experience with installing Arch (like you can install arch with a blind fold).
• Read everything through

We will ne two of them, one for /boot and the other one will be a btrfs partition with subvolumes.

1. /dev/sda1 - this will be /boot with vfat filesystem because UEFI or syslinux for legacy BIOS boot

# Take note of this:
# - The first thing you need is to identify which disk you're going to use. For the purpose of this guide, it will be /dev/sda
#   Be VERY CAREFUL if you have more than one disk on your computer, and DOUBLE CAREFUL if one of them is the one with your backups
# - Since btrfs does not support swapfiles (yet), we'll create a swap partition. In this guide, it will NOT be encrypted
