Release 1.0

Known Issues
Tensorflow build fetch error Due to possible checksum changes in the files hosted at https://gitlab.arm.com/kleidi/kleidiai/-/archive/, TensorFlow Lite may no longer be built from source. Unless these files are already present in your local download cache, the build will fail. As a workaround, the Machine Learning package must be removed from the build. Add the following to the conf/local.conf:
For the image fsl-image-gui/fsl-image-gui-chromium:
RDEPENDS:packagegroup-variscite-imx-ml:mx9-nxp-bsp:remove = "packagegroup-imx-ml"
For the image fsl-image-qt6, in addition:
RDEPENDS:packagegroup-imx-gopoint:remove = "imx-nnstreamer-examples"
Inaccurate timing on audio playback Audio Playback can fail or may be perceived as timing inaccurate, especially when different sample rates are used and the audio device is accessed directly. As a workaround, it is recommended to either use the default sample rate (48kHz), start playback twice in a row, or use the mixer instead of direct access. The underlying reason is a faulty synchronization of the clock settings, which can result in a mismatch between the SAI and the codec clock.
Note
Allow using only one camera: Due to a limitation in the current kernel implementation of MIPI-CSI control chain, only the cameras actually present must be enabled. In order to use a single camera, only that specific camera can be enabled, while the other and related chain items must be disabled.
