Using External Toolchain

Option 1: Give tarball URL

Specify URL for the tarball in BR_TOOLCHAIN_EXTERNAL_URL

Example:

BR_TOOLCHAIN_EXTERNAL_URL=http://artifactory/my-toolchain.tar.xz

In this case you will have to deselect BR2_PRIMARY_SITE_ONLY option

Option 2: Give tarball relative dl path

If BR2_PRIMARY_SITE_ONLY option is selected then you have to keep the toolchain inside dl/toolchain-external-custom/ directory and pass the name of tarball to BR_TOOLCHAIN_EXTERNAL_URL

Example:

BR2_PRIMARY_SITE="http://artifactory/buildroot-sources"
BR2_PRIMARY_SITE_ONLY=y
BR_TOOLCHAIN_EXTERNAL_URL=my-toolcahin.tar.xz

This will extract the toolchain to buildroot’s build directory output/host/opt/ext-toolchain
