Hi Francois,<br />
<br />
I did some research on the topic and it appears to be specific to Pi3's, because of how UART is used by Bluetooth by default. If you are not using Bluetooth you can add &quot;dtoverlay=pi3-disable-bt&quot;<wbr /> to your config.txt, which will disable BT, and address your issue. <br />
<br />
A more in depth article is <a href="https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/" rel="ugc">here.</a><br />
<br />
Hope this helps,<br />

<div class="content wysiwyg-content">
Pi3 with Raspbian Stretch (fully update/upgraded) will not boot with enable_uart=1 in /boot/config.txt &nbsp;-- bunch of stuff appears on the screen.<br />
If I set it enable_uart=0, no problem.<br />
My issue is that I need to use the UART Rx/Tx functionality.
