External Toolchain in Buildroot
Using External Toolchain Option 1: Give tarball URL Specify URL for the tarball in BR_TOOLCHAIN_EXTERNAL_URL Example: BR_TOOLCHAIN_EXTERNAL_URL=http://192.168.101.52:8082/artifactory/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://192.168.101.52:8082/artifactory/dl" BR2_PRIMARY_SITE_ONLY=y BR_TOOLCHAIN_EXTERNAL_URL=nvrx-rk3588-toolcahin.tar.xz This will extract the toolchain to buildroot’s build directory output/host/opt/ext-toolchain ...
