+Getting Started with Contiki for TI CC26xx
+==========================================
+
+This guide's aim is to help you start using Contiki for TI's CC26xx. The
+platform supports two different boards:
+
+* SmartRF 06 Evaluation Board with a CC26xx Evaluation Module (relevant files
+  and drivers are under `srf06/`)
+* CC26xx SensorTag 2.0 (relevant drivers under `sensortag/`)
+
+The CPU code, common for both platforms, can be found under `$(CONTIKI)/cpu/cc26xx`.
+The port was developed and tested with CC2650s, but the intention is for it to
+work with the CC2630 as well. Thus, bug reports are welcome for both chips.
+Bear in mind that the CC2630 does not have BLE capability.
+
+This port is only meant to work with 7x7mm chips
+
+This guide assumes that you have basic understanding of how to use the command
+line and perform basic admin tasks on UNIX family OSs.
+
+Port Features
+=============
+The platform has the following key features:
+
+* Deep Sleep support with RAM retention for ultra-low energy consumption.
+* Support for CC26xx RF in IEEE as well as BLE mode (BLE support is very basic
+  since Contiki does not provide a BLE stack).
+
+In terms of hardware support, the following drivers have been implemented:
+
+* SmartRF06 EB peripherals
+  * LEDs
+  * Buttons
+  * UART connectivity over the XDS100v3 backchannel
+* SensorTag 2.0
+  * LEDs
+  * Buttons (One of the buttons can be used as a shutdown button)
+  * Reed relay
+  * Motion Processing Unit (MPU9250 - Accelerometer, Gyro)
+  * BMP280 sensor
+  * TMP007 sensor
+  * SHT21 sensor
+  * OPT3001 sensor
+  * Buzzer
+  * External SPI flash
+
+Examples
+========
+The port comes with two examples: A very basic example and a mode advanced one
+(web demo). The former demonstrates how to read sensors and how to use board
+peripherals. It also demonstrates how to send out BLE advertisements.
+The latter includes a CoAP server, an MQTT client which connects and publishes
+to the IBM quickstart service, a net-based UART and lastly a web server that
+can be used to configure the rest of the example.
+
+More details about those two examples can be found in their respective READMEs.
+
+Requirements
+============
+To use the port you need:
+
+* TI's CC26xxware sources (more below)
+* Software to program the nodes. Use TI's SmartRF Flash Programmer
+* A toolchain to build firmware: The port has been developed and tested with
+  GNU Tools for ARM Embedded Processors <https://launchpad.net/gcc-arm-embedded>.
+  The port was developed and tested using this version:
+
+    $ arm-none-eabi-gcc -v
+    [...]
+    gcc version 4.9.3 20141119 (release) [ARM/embedded-4_9-branch revision 218278] (GNU Tools for ARM Embedded Processors)
+
+* You may also need other drivers so that the SmartRF can communicate with your
+operating system and so that you can use the chip's UART for I/O. Please read
+the section ["Drivers" in the CC2538DK readme](https://github.com/contiki-os/contiki/tree/master/platform/cc2538dk#drivers).
+
+Environment
+===========
+To use this port, you will need to download and extract CC26xxware sources, 
+provided by TI here http://www.ti.com/tool/cc26xxware. Once you have done this, you will need to configure the Contiki
+build system so that it can locate and compile them as part of the build process.
+
+To do this, you will need to set the following environment variable:
+
+*  `TI_CC26XXWARE`
+
+    Stores the path to a directory containing the following:
+
+    * cc26xxware sources under `$(TI_CC26XXWARE)/driverlib`
+    * cc26xxware includes under `$(TI_CC26XXWARE)/inc`
+    * Startup files under `$(TI_CC26XXWARE)/startup_files`
+
+This _must_ be a path relative to the Contiki source directory. For
+example, if Contiki is in `/home/user/contiki-2.x` and the CC26xxware is in
+`/home/user/cc26xxware`, then `TI_CC26XXWARE` must be set to `../cc26xxware`
+
+The variable can be set within the example's Makefile, by adding this:
+
+    TI_CC26XXWARE=../cc26xxware
+
+or you can use an environment variable, like so:
+
+    export TI_CC26XXWARE=../cc26xxware
+
+Filename conflicts between Contiki and CC26xxware
+=================================================
+There is a file called `timer.c` both in Contiki as well as in CC26xxware. The
+way things are configured now, we don't use the latter. However, if you need to
+start using it at some point, you will need to rename it:
+
+From `$(TI_CC26XXWARE)/driverlib/cc26xx/source/timer.c` to `driverlib-timer.c`
+
+Sensortag vs Srf06
+==================
+To build for the sensortag, set `BOARD=sensortag`. You can do that by exporting
+it as an environment variable, by adding it to your Makefile or by adding it to
+your make command as an argument
+
+If the `BOARD` variable is not equal to `sensortag`, an image for the Srf06
+CC26XXEM will be built instead.
+
+If you want to switch between building for one platform to the other, make
+certain to `make clean` before building for the new one, or you will get linker
+errors.
+
+Low Power Operation
+===================
+The platform takes advantage of the CC26xx's power saving features. In a
+nutshell, here is how things work:
+
+* When the RF is TXing, the CPU will enter sleep mode and will resume after TX
+  has completed.
+* When there are no events in the Contiki event queue, the chip will enter
+  'some' low power mode (more below).
+
+We do not use pre-defined power profiles (e.g. as mentioned in the TRM or as
+we do for the CC2538 with LPM1, LPM2 etc). Each time we enter low power
+operation, we either put the CM3 to sleep or to deep sleep. The latter case is
+highly configurable: the LPM engine allows other code modules to register
+themselves for notifications and to configure low power operation. With these
+facilities, a module can e.g. prohibit deep sleep altogether, or it can request
+that a power domain be kept powered. The LPM engine will turn off as many
+CC26xx components as it can while satisfying all restrictions set by registered
+modules.
+
+To determine which power mode to use, the following logic is followed:
+
+* The deepest available low power mode can be hard-coded by using
+  the `LPM_MODE_MAX_SUPPORTED` macro in the LPM driver (`lpm.[ch]`). Thus, it
+  is possible to prohibit deep sleep altogether.
+* Code modules which are affected by low power operation can 'register'
+  themselves with the LPM driver.
+* If the projected low-power duration is lower than `STANDBY_MIN_DURATION`,
+  the chip will simply sleep.
+* If the projected low power duration is sufficiently long, the LPM will visit
+  all registered modules to query the maximum allowed power mode (maximum means
+  sleep vs deep sleep in this context). It will then drop to this power mode.
+  This is where a code module can forbid deep sleep if required.
+* All registered modules will be notified when the chip is about to enter
+  deep sleep, as well as after wake-up.
+
+When the chip does enter deep sleep:
+
+* The RF Core, VIMS, SYSBUS and CPU power domains are always turned off. Due to
+  the way the RF driver works, the RFCORE PD should be off already.
+* Peripheral clocks stop
+* The Serial and Peripheral power domains are turned off, unless an LPM module
+  requests them to stay operational. For example, the net-uart demo keeps the
+  serial power domain powered on and the UART clocked under sleep and deep
+  sleep in order to retain UART RX functionality.
+* If both SERIAL and PERIPH PDs are turned off, we also switch power source to
+  the uLDO for ultra low leakage under deep sleep.
+
+The chip will come out of low power mode by one of the following events:
+
+* Button press or, in the case of the SensorTag, a reed relay trigger
+* Software clock tick (timer). The clock ticks at 128Hz, therefore the maximum
+  time we will ever spend in a sleep mode is 7.8125ms. In hardware terms, this
+  is an AON RTC Channel 2 compare interrupt.
+* Rtimer triggers, as part of ContikiMAC's sleep/wake-up cycles. The rtimer
+  sits on the AON RTC channel 0.
