141 The M4 Core is configured to run at a 200 MHz clock speed.
152 The 96Boards Meerkat96 board doesn't have QSPI flash for the M4 and it needs
153 to be started by the A7 core. The A7 core is responsible to load the M4 binary
154 application into the RAM, put the M4 in reset, set the M4 Program Counter and
155 Stack Pointer, and get the M4 out of reset. The A7 can perform these steps at
158 The M4 can use up to 5 different RAMs. These are the memory mapping for A7 and M4:

204 Below you will find the instructions to load and run Zephyr on M4 from
205 A7 using u-boot.
208 plug into the board. Power it up and stop the u-boot execution.
209 Set the u-boot environment variables and run the zephyr.bin from the
212 .. code-block:: console
241 `J-Link Tools`_ and `NXP iMX7D Connect CortexM4.JLinkScript`_.
243 To run Zephyr Binary using J-Link create the following script in order to
246 get-pc-sp.sh:
247 .. code-block:: console
253 pc=$(od -An -N 8 -t x4 $firmware | awk '{print $2;}')
254 sp=$(od -An -N 8 -t x4 $firmware | awk '{print $1;}')
260 Get the SP and PC from firmware binary: ``./get-pc-sp.sh zephyr.bin``
261 .. code-block:: console
266 Plug in the J-Link into the board and PC and run the J-Link command line tool:
268 .. code-block:: console
270 …/usr/bin/JLinkExe -device Cortex-M4 -if JTAG -speed 4000 -autoconnect 1 -jtagconf -1,-1 -jlinkscri…
274 1. Put the M4 core in reset
278 5. Get the M4 core out of reset
