+<p>We can do Asymmetric Multi Processing on K230 using the little core as
master and the big core as remote.</p>
+<p>Take the <code class="docutils literal notranslate"><span
class="pre">canmv230/master</span></code> and <code class="docutils literal
notranslate"><span class="pre">canmv230/remote</span></code> configurations to
build the master and remote NuttX images respectively. They are both kernel
builds derived from <code class="docutils literal notranslate"><span
class="pre">canmv230/nsbi</span></code> mentioned above, so we can follow above
kernel mode build steps to build them.</p>
+<p>Let’s put the NuttX image files as <code class="docutils literal
notranslate"><span class="pre">master.bin</span></code> and <code
class="docutils literal notranslate"><span class="pre">remote.bin</span></code>
respectively on the TFTP folder. To run them on K230 device, do the following
from U-Boot console:</p>
+<div class="highlight-console notranslate"><div
class="highlight"><pre><span></span><span class="go">k230# usb start</span>
+<span class="go">k230# ping $serverip</span>

+<span class="go">k230# tftp 8000000 master.bin</span>
+<span class="go">k230# go 8000000</span>
+</pre></div>
+</div>
+<p>Then we should see the “master> ” prompt, this is the master console.
where we can further run the <code class="docutils literal notranslate"><span
class="pre">cu</span></code> command and press Return key to see the remote
console, within remote console type <code class="docutils literal
notranslate"><span class="pre">~.</span></code> to get back to the master
console.</p>
+<p>There is a <a class="reference external"
href="https://github.com/apache/nuttx/pull/11673";>session log</a> showing how
to enter remote node and check file system status then get back and check
master file system status.</p>
