Build instructions are documented at Spresense SDK Getting Started Guide.
Install the necessary packages and GCC ARM toolchain for cross-compilation.
$ wget https://raw.githubusercontent.com/sonydevworld/spresense/master/install-tools.sh
$ bash install-tools.sh
Go to the folder where you cloned the {SDK_FULL}, and enter the sdk
folder name:
$ cd spresense/sdk
Set up the SDK configuration
$ tools/config.py examples/hello
Build the example image:
$ make
A nuttx.spk
file appears in the sdk
folder when this step has successfully finished.
This file is the final result and can be flashed into the your board.
A pre-compiled docker container is available with all the pre-requisite that is needed in order to build the Spresense SDK.
In order to start using it simply type:
$ source spresense_env.sh
This script will create an alias spresense
which should proceed the regular SDK build scripts and Make commands.
Examples:
SpresenseSDK: $ spresense tools/config.py examples/hello
SpresenseSDK: $ spresense make
