linux-libre-firmware/INSTALL

Briefly, running "make" without specifying any targets will build
everything. You may not necessarily want everything though and can
also specify targets to make. For example:

    make av7110

Please see the included Makefile for a list of all available targets.

Once the desired things are built, "make install" will put them into
the appropriate place, which is /lib/firmware by default although you
can override this with something like:

    make prefix=/desired/path install

In order to build everything you will need the following on the host
system:

    * A C/C++ compiler, like GCC
    * Cmake
    * dfu-util - Device Firmware Upgrade Utilities
    * GNU Bison/YACC
    * GNU Flex
    * GNU Gperf
    * GNU Make
    * GNU Wget
    * GNU C cross-compiler for AVR
    * Standard C library for Atmel AVR
    * GNU C cross-compiler for ARM:
        - arm-linux-gnueabi-gcc
        - arm-linux-gnueabi-ld
        - arm-linux-gnueabi-objcopy
        - arm-none-eabi-gcc
        - arm-none-eabi-objcopy
        - arm-none-eabi-as

On GNU/Linux distros that use apt you can install these with:

    apt install gcc-avr avr-libc binutils-arm-linux-gnueabi \
    binutils-arm-none-eabi bison cmake dfu-util flex g++ gcc \
    gcc-arm-linux-gnueabi gcc-arm-none-eabi gperf make wget

CARL9170 Firmware Configuration
-------------------------------
When building the carl9170 firmware you will be prompted with
configuration questions.

atusb: Firmware for the ATUSB IEEE 802.15.4 USB Adapter
-------------------------------------------------------

To flash the firmware you need dfu-util on the host. Issue

    dfu-util -d 20b7:1540 -D atusb.dfu

right after plugging the device into the USB port while the red led is
still on.

Refer to the included README file for more information.
