How to install zephyr

Embeded : 2019. 8. 21. 11:56

zephyr 관리하는 툴인 west 를 설치.

$ pip3 install --user -U west

이렇게 --user 하면 계정 로컬에 설치됨

/home/lionelj/.local/bin 에 west 깔림. 그래서 여기를 PATH로 잡아줌.

$ west init zephyrproject
$ cd zephyrproject
$ ls

drwxrwxr-x  4 lionelj lionelj 4.0K  8월 21 11:53 .
drwxrwxr-x  3 lionelj lionelj 4.0K  8월 21 11:52 ..
drwxrwxr-x  2 lionelj lionelj 4.0K  8월 21 11:53 .west
drwxrwxr-x 22 lionelj lionelj 4.0K  8월 21 11:53 zephyr

$ west update

cmake 가 필요해서 설치해줌.

$ sudo apt install cmake

zephyr SDK 가 또 있어야 되네.

https://github.com/zephyrproject-rtos/sdk-ng 에 가보면 다운로드 방법 있음.

RP build 버전은

https://builds.zephyrproject.org/zephyrproject-rtos/sdk-ng//zephyr-sdk--setup.run

정식 릴리즈는

https://github.com/zephyrproject-rtos/sdk-ng/releases

여기서 받으면 되는 모양.

일단. zephyr-sdk-0.10.3-setup.run 를 받는다.

$ chmod +x zephyr-sdk-0.10.3-setup.run

$ ./zephyr-sdk-0.10.3-setup.run

No permission, please run as 'sudo'

sudo 하라고 한다.
$ sudo ./zephyr-sdk-0.10.3-setup.run

[sudo] lionelj의 암호:

Success installing SDK. SDK is ready to be used.

이렇게 하면 sdk 는 설치된다.

인터넷에 보니까 sdk를 yocto 로 만든거 같다고 하는 사람도 있는데 뒤에 -ng 붙은거보니 crosstool-ng로 만든거 같기도 하고..

아무튼 sdk 를 설치하고 SDK 환경 변수를 맞춰준다.

export ZEPHYR_SDK_INSTALL_DIR="/opt/zephyr-sdk/"

$ cd zephyrproject/zephyr

ninja 가 없다.

$sudo apt-get install ninja-build

깔고 다시 하면 됨.
