 ## eMMC
 
-The Odroid XU4 has a hidden boot sector that is only visible on the Odroid itself (can't be written by a card reader). There are a couple possibilities:
-1) If the eMMC already had a working image before flashing HassOS:
-* It will be booting to uBoot (but no further). 
-    * If you have the serial adapter, you should be able to enter `distro_bootcmd` at the uboot prompt to continue booting.
-    * If not, flash the HassOS image to an SD card and boot off that temporarily (while the eMMC is also plugged in).
-* Once booted, login at the prompts and then enter `dd if=/dev/mmcblk0 of=/dev/mmcblk0boot0 bs=512 skip=63 seek=62 count=1440` at the linux prompt.
-* Reboot with eMMC (don't forget to flip the boot switch to eMMC)
-2) Clean/wiped/corruped boot sector:
-* You'll need to follow [Hardkernel's instructions](https://forum.odroid.com/viewtopic.php?f=53&t=6173) to get a working boot sector. Then flash HassOS and follow instructions above.
-* Alternatively, you can try flash HassOS to both an SD and eMMC, then boot off the SD with the eMMC also plugged in, then run `dd if=/dev/mmcblk1 of=/dev/mmcblk0boot0 bs=512 skip=1 seek=0 count=16381` at the Linux prompt. Note that this is untested, but in theory should work..
+The ODROID XU4 uses the eMMC boot partition to boot from. Typically eMMC readers can't write to this eMMC boot partition. There are a couple of possibilities:
+
+1. **Working** e.g. the eMMC already had a working image before flashing HassOS:
+   - It will be booting to U-Boot (but no further).
+     - If you have the serial adapter, you should be able to enter `distro_bootcmd` at the uboot prompt to continue booting.
+     - If not, flash the HassOS image to an SD card and boot off that temporarily (while the eMMC is also plugged in).
+   - Once booted, login at the prompts and then enter `dd if=/dev/mmcblk0 of=/dev/mmcblk0boot0 bs=512 skip=63 seek=62 count=1440` at the linux prompt.
+   - Reboot with eMMC (don't forget to flip the boot switch to eMMC)
+2. **Not Working** e.g. a clean/wiped/corruped eMMC boot partition:

 If you are getting permissions issues when using the dd command, try disabling RO:
 `echo 0 > /sys/block/mmcblk0boot0/force_ro`
 to re-enable after running dd:
 `echo 1 > /sys/block/mmcblk0boot0/force_ro`
+
 ## Console
 
 By default, console access is granted over the serial header and over HDMI. Certain startup messages will only appear on the serial console by default. To show the messages on the HDMI console instead, swap the order of the two consoles in the `cmdline.txt` file on the boot partition. You can also delete the SAC2 console if you don't plan on using the serial adapter.

-# Home Assistant Operating-System
-Hass.io OS based on [buildroot](https://buildroot.org/). It's a hypervisor for Docker and supports various kind of IoT hardware. It is also available as virtual appliance. The whole system is optimized for embedded system and  security. You can update the system simple with OTA updates or offline updates.
+# Home Assistant Operating System
 
-This is a embedded Linux which work different as a normal Linux distribution. The system is designed to run with less as possible I/O and full optimized for what is needed to be. Not more and not less. If you don't have expirence with embedded systems, that will be the point to go out of this repository. All docs are for developer with embedded background.
+Home Assistant Operating System (formerly HassOS) is an operating system optimized for hosting [Home Assistant](https://www.home-assistant.io) and its [Add-ons](https://www.home-assistant.io/addons/).
 
-## Focus
+Home Assistant Operating System uses Docker as Container engine. It by default deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is **not** based on a regular Linux distribution like Ubuntu. It is built using [buildroot](https://buildroot.org/) and it is optimized for running Home Assistant, especially on single board compute (SBC) devices like the Pi, ODROID, NUC and Tinker Board (see supported hardware below).
 
-- Barebox as bootloader on EFI
-- U-Boot as bootloader on IoT
-- Linux/Buildroot LTS
-- RAUC for OTA updates
-- SquashFS LZ4 as filesystem
-- Docker-CE
-- AppArmor protected
-- ZRAM LZ4 for /tmp, /var, swap
+## Features
+
+- Lightweight and memory-efficient
+- Minimized I/O
+- Over The Air (OTA) updates
+- Offline updates
+- Modular using Docker
+
+## Supported hardware
+

+- Hardkernel ODROID
+- Intel NUC
+- Asus Tinker Board
+- Virtual appliances

+
+## Getting Started
+
+If you just want to use Home Assistant the official [getting started guide](https://www.home-assistant.io/getting-started/) and [installation instructions](https://www.home-assistant.io/hassio/installation/) take you through how to download Home Assistant Operating System and get it running on your machine.
+
+If you're interested in finding out more about Home Assistant Operating System and how it works read on...
+
+## HassOS components
+
+- **Bootloader:**
+  - [Barebox](https://barebox.org/) for devices that support EFI
+  - [U-Boot](https://www.denx.de/wiki/U-Boot) for devices that don't support EFI
+- **Operating System:**
+  - [Buildroot](https://buildroot.org/) LTS Linux
+- **File Systems:**
+  - [SquashFS](https://www.kernel.org/doc/Documentation/filesystems/squashfs.txt) for read-only file systems (using LZ4 compression)
+  - [ZRAM](https://www.kernel.org/doc/Documentation/blockdev/zram.txt) for `/tmp`, `/var` and swap (using LZ4 compression)
+- **Container Platform:**
+  - [Docker Engine](https://docs.docker.com/engine/) for running Home Assistant components in containers
+- **Updates:**
+  - [RAUC](https://rauc.io/) for Over The Air (OTA) and USB updates
+- **Security:**
+  - [AppArmor](https://apparmor.net/) Linux kernel security module
+
+If you don't have experience with these, embedded systems, buildroot or the build process for Linux distributions, then please read up on these topics. The rest of the documentation in this project is for developers and assumes you have experience of embedded systems or a strong understanding of the internal workings of operating systems.

-Subject: [PATCH] FROMLIST: clk: meson: g12a: fix gp0 and hifi ranges
-
-While some SoC samples are able to lock with a PLL factor of 55, others
-samples can't. ATM, a minimum of 60 appears to work on all the samples
-I have tried.
-
-Even with 60, it sometimes takes a long time for the PLL to eventually
-lock. The documentation says that the minimum rate of these PLLs DCO
-should be 3GHz, a factor of 125. Let's use that to be on the safe side.
-
-With factor range changed, the PLL seems to lock quickly (enough) so far.
-It is still unclear if the range was the only reason for the delay.

+Subject: [PATCH 03/14] ASoC: meson: gx-card: fix sound-dai dt schema
+
+There is a fair amount of warnings when running 'make dtbs_check' with
+amlogic,gx-sound-card.yaml.
+
+Ex:
+arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:1: missing phandle tag in 0
+arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:2: missing phandle tag in 0
+arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0: [66, 0, 0] is too long
+
+The reason is that the sound-dai phandle provided has cells, and in such
+case the schema should use 'phandle-array' instead of 'phandle'.
+

+
+On Amlogic Meson G12b platform, similar to fclk_div3, the fclk_div2
+seems to be necessary for the system to operate correctly as well.
+
+Typically, the clock also gets chosen by the eMMC peripheral. This
+probably masked the problem so far. However, when booting from a SD
+card the clock seems to get disabled which leads to a system freeze.
+
+Let's mark this clock as critical, fixing boot from SD card on G12b
+platforms.

+Subject: [PATCH 14/14] usb: cdc-acm: fix cooldown mechanism
+
+Commit a4e7279cd1d1 ("cdc-acm: introduce a cool down") is causing
+regression if there is some USB error, such as -EPROTO.
+
+This has been reported on some samples of the Odroid-N2 using the Combee II
+Zibgee USB dongle.
+
+> struct acm *acm = container_of(work, struct acm, work)
+
+is incorrect in case of a delayed work and causes warnings, usually from
+the workqueue:
+
+> WARNING: CPU: 0 PID: 0 at kernel/workqueue.c:1474 __queue_work+0x480/0x528.
+
+When this happens, USB eventually stops working completely after a while.
+Also the ACM_ERROR_DELAY bit is never set, so the cooldown mechanism
+previously introduced cannot be triggered and acm_submit_read_urb() is
+never called.
+
+This changes makes the cdc-acm driver use a single delayed work, fixing the
+pointer arithmetic in acm_softint() and set the ACM_ERROR_DELAY when the
+cooldown mechanism appear to be needed.
+
+Fixes: a4e7279cd1d1 ("cdc-acm: introduce a cool down")

+Subject: [PATCH 3/3] usb: cdc-acm: fix cooldown mechanism
+
+Commit a4e7279cd1d1 ("cdc-acm: introduce a cool down") is causing
+regression if there is some USB error, such as -EPROTO.
+
+This has been reported on some samples of the Odroid-N2 using the Combee II
+Zibgee USB dongle.
+
+> struct acm *acm = container_of(work, struct acm, work)
+
+is incorrect in case of a delayed work and causes warnings, usually from
+the workqueue:
+
+> WARNING: CPU: 0 PID: 0 at kernel/workqueue.c:1474 __queue_work+0x480/0x528.
+
+When this happens, USB eventually stops working completely after a while.
+Also the ACM_ERROR_DELAY bit is never set, so the cooldown mechanism
+previously introduced cannot be triggered and acm_submit_read_urb() is
+never called.
+
+This changes makes the cdc-acm driver use a single delayed work, fixing the
+pointer arithmetic in acm_softint() and set the ACM_ERROR_DELAY when the
+cooldown mechanism appear to be needed.
+

-From 5e960cc9b208c53d5385d5a2f6c7f380e9499d4c Mon Sep 17 00:00:00 2001
-From: Alexandru Costache <alexandru@balena.io>
-Date: Wed, 18 Mar 2020 16:54:28 +0100
-Subject: [PATCH] Add a retry limit when writing to uart console
-
-Seems that if the serial console is incorrectly
-configured in the dtb, writing to it may block indefinitely,
-thus preventing the board from booting.
-
-Let's add a retry count to unblock in such cases.
-
-Upstream-status: Inappropriate [configuration]
