#include &lt;nuttx/arch.h&gt;

int up_cpu_initialize(void);

<p><b>Description</b>:</p>
<ul>
<p>
After the CPU has been started (via <code>up_cpu_start()</code>) the system will call back into the architecture-specific code with this function on the thread of execution of the newly started CPU.
This gives the architecture-specific a chance to perform ny initial, CPU-specific initialize on that thread.
