FATAL error ST-Link No MCU device found
<p>I'am using IAR Workbench and I am having hard time to flash my STM32F407VG I got:</p>

<blockquote>
  <p>FATAL error ST-Link No MCU device found.</p>
</blockquote>

<ul>
<li>The USB cable connecting the laptop and the MCU is new so I don't think it's the problem.</li>
<li>ST-Link en.stsw-link009 is installed </li>
</ul>

<p>When I go to project options Debugger > ST-Link > Reset > connect during reset and try to download again I got:</p>

<blockquote>
  <p>Warning stack pointer is setup to incorrect alignement stack <code>addr = 0x00000016</code> after the download progress bar stay blocked.</p>
</blockquote>

<p>By navigating in the option menu I find it's possible to adjust CPU frequency actually it's 72 MHz, the default one, I changed it to 168 MHz, the CPU frequency but the problem remains.</p>

<p>Could you please suggest me some solutions to debug/resolve the problem.</p>

<p><strong>Edit</strong></p>

<p>I have used STM32 ST-Link Utility and i succeded to connect to the board, But the problem with my IDE is not resolved yet.</p>
