Change List	Description
Release 1.0
Initial Yocto Walnascar 6.12.20_2.2.0 release	Based on NXP Yocto Walnascar 6.12.20_2.0.0 and NXP Linux Kernel lf-6.12.y

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.
The following Variscite BSP feature are not supported yet:	WBE device tree
