6 The i.MX93 Evaluation Kit (MCIMX93-EVK board) is a platform designed to show
8 small and low cost package. The MCIMX93-EVK board is an entry-level development
12 i.MX93 MPU is composed of one cluster of 2x Cortex-A55 cores and a single
13 Cortex®-M33 core. Zephyr OS is ported to run on one of the Cortex®-A55 core.

165 U-Boot "cpu" command is used to load and kick Zephyr to Cortex-A secondary Core, Currently
166 it is supported in : `Real-Time Edge U-Boot`_ (use the branch "uboot_vxxxx.xx-y.y.y,
167 xxxx.xx is uboot version and y.y.y is Real-Time Edge Software version, for example
168 "uboot_v2023.04-2.9.0" branch is U-Boot v2023.04 used in Real-Time Edge Software release
169 v2.9.0), and pre-build images and user guide can be found at `Real-Time Edge Software`_.

180 Use U-Boot to load and kick zephyr.bin to Cortex-A55 Core1:
182 .. code-block:: console
187 Or use the following command to kick zephyr.bin to Cortex-A55 Core0:
189 .. code-block:: console
195 for example, with the :zephyr:code-sample:`synchronization` sample:
