 I’m currently working with the nrf9160 sip on a bare metal firmware project. I know the official support path is only with Zephyr OS but I’m facing an issue I’m not able to solve so far. 
 I want to take advantage of the Trustzone feature, to</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 21 Oct 2019 11:09:39 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/53381/nrf9160-non-secure-boot-hard-fault" /><item><title>RE: nrf9160 non-secure boot hard-fault</title><link>https://devzone.nordicsemi.com/thread/215881?ContentTypeID=1</link><pubDate>Mon, 21 Oct 2019 11:09:39 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:361fdd45-a625-435e-a2b4-68d104a57854</guid><dc:creator>Heidi</dc:creator><description>&lt;p&gt;Hi again, I would suggest &lt;a href="https://support.developer.arm.com/my-cases/open-case/?_ga=2.116449222.1139529472.1571655920-598507796.1571655920"&gt;opening a case&lt;/a&gt; with ARM on their website regarding questions related to Cortex-M33 behavior.&lt;/p&gt;

I guess my question was more on the cortex m33 behavior and not specifically tied to Zephyr. I was just looking for some information about what the firmware should do before jumping to a non-secure area. I configured the SPU, set the addresses for MSP_NS and SCB_NS VTOR and I&amp;#39;m just wondering if other things should be done such as configuring the MPU, etc...&lt;/p&gt;
&lt;p&gt;Thanks,&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Unfortunately, we don&amp;#39;t offer support on bare metal programming and we highly recommend anybody developing on the nRF9160 to use Zephyr. I will happily assist you with any Zephyr related questions.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
&lt;p&gt;Heidi&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
