Tuukka Turunen from The Qt Company shared some fantastic news in his post Aligning with the Yocto Project .
We have created a separate Boot to Qt meta layer, meta-boot2qt, which takes care of building the images and toolchains for the reference devices. The meta-boot2qt layer integrates all the required BSP meta layers, so there is no manual configurations necessary when starting Yocto build for one of the Qt reference devices. The layer was previously available only for our commercial customers, but with Qt 5.7 we have open sourced it as well.
The Boot2Qt meta layer comes with support for all three versions of the Raspberry Pi, many i.MX6 boards (Nitrogen6x, SABRE, Colibri, etc.), the NVIDIA Drive CX and for the Intel NUC. This should make the live of embedded Qt developers a lot easier. Thank you very much, Trolls!
