Building the SDK requires a Yocto build environment configured for meta-tq or ci-meta-tq The setup of the build environment is described on the corresponding Yocto quickstart of the TQMaRZG2x.
bitbake -c populate_sdk core-image-hmi
After building the SDK, the installation script is located in …/tmp/deploy/sdk/ in the build directory
e.g. for rocko.TQMaRZG2x.BSP.SW.0010
tq-dumpling-wayland-rzg2-glibc-x86_64-core-image-qt-aarch64-toolchain-2.4.3.sh
By default the sdk will be installed to /opt/tq-dumpling-wayland-rzg2/2.4.3/ the install path can be changed during the installtion.
