Build Image and SDK

Precondition for Ubuntu 22.04

sudo apt install -y wget unzip build-essential git bc swig libncurses-dev libpython3-dev libssl-dev cpio rsync subversion python3 mercurial imagemagick btrfs-progs

Clone buildroot repo

git clone https://github.com/MiyooCFW/buildroot.git
cd buildroot

You can build four types of source

Shared uClibc Image and SDK
Shared musl Image and SDK
Static uClibc SDK only
Static musl SDK only

NOTE: You can build only one type of source, after each build you need to clean workspace by using make clean

NOTE: Difference between static and shared: Static library Shared_library

NOTE: You will also need at least 10GB of free space before you can proceed

NOTE: This can take a long time!

Build uClibc image and SDK shared

make miyoo_uclibc_defconfig
make sdk

Build musl image and SDK shared

make miyoo_musl_defconfig
make sdk

Build uClibc SDK static

make miyoo_static_uclibc_defconfig
make sdk

Build musl SDK static

make miyoo_static_musl_defconfig
make sdk

NOTE: If you have a multicore CPU, you can increase build speed with: make -j ${YOUR_CPU_COUNT}

Install image

Img will be in the output directory e.g.

miyoo-cfw-2.0.0-67298a0_uclibc-BETAv2.img

Install SDK

SDK will be in the output directory

arm-miyoo-linux-uclibcgnueabi_sdk-buildroot.tar.gz

Unpack arm-miyoo-linux-uclibcgnueabi_sdk-buildroot.tar.gz to /opt/miyoo, additionally you can run relocate-sdk.sh in custom SDK path

gzip -d arm-miyoo-linux-uclibcgnueabi_sdk-buildroot.tar.gz
tar xvf arm-miyoo-linux-uclibcgnueabi_sdk-buildroot.tar
mv arm-miyoo-linux-uclibcgnueabi_sdk-buildroot miyoo
sudo cp -a miyoo /opt/
/opt/miyoo/relocate-sdk.sh

Your SDK is ready to use
