&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I am using an NXP LPC55S69 with a Cortex M33 and Arm trustzone. The application I try to develop does some calculations in secure world and then pass the result to non-secure world where the WiFi should be located to transmit the data. For the WiFi I use the Mikroe WiFi 10 click which is placed in the Mikro bus of the board. I desparately try to init the board in the non secure world but keep getting hardfaults. Initialization in secure world works fine but I really want it to be in the non secure world but cannot figure out how to solve this. I would be really thankful for every help if anybody has some suggestiones or solved a simular issue.&lt;/p&gt;
&lt;p&gt;Thanks and best regards,&lt;/p&gt;

&lt;p&gt;I am using the LPC55s69 in combination with wifi10click board. I want to develop a secure application that does some calculation and then sends the result over wifi. The secure application is already working but i am struggling quite a bit with the wifi and maybe someone can give me some advice so i can finish this. The wifi should be running as an unsecure application so I have the calculation totally seperated. But when I want to setup the wifi as an unsecure application (setting up the pins and all that) I keep getting hardfaults. When the Wifi runs on the secure side everything works fine. What do I have to change so i can setup the wifi board form unsecure world or is this just not possible and must be placed in secure world ? So if anyone does have some experience with Wifi in combination with trustzone i am glad for every advice.&lt;br /&gt;&lt;br /&gt;Thanks in advance and best regards,&lt;br /&gt;Lukas&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>Ask A Question I</title><link>https://community.arm.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09</link><pubDate>Wed, 11 Nov 2020 00:02:36 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:76b56120-7559-4973-b929-e1b822a9f010</guid><dc:creator /><description>Ask a question in a forum.</description></item><item><title>QCA400x undefined symbol Driver_SPI</title><link>https://community.arm.com/developer/tools-software/tools/f/keil-forum/48034/qca400x-undefined-symbol-driver_spi</link><pubDate>Wed, 11 Nov 2020 18:02:58 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:70373c1a-5573-4677-aa43-3c3d08590e17</guid><dc:creator>beze</dc:creator><description>&lt;p&gt;Hello,&lt;br /&gt;&lt;br /&gt;I am using the lpc55s69 from NXP in combination with the &lt;span style="left:408.683px;top:428.427px;"&gt;mikroe 10 click (a wifo board based on qualcomm qca4004x). I tried to set up the wifi with CMSIS WiFi driver from MDK-Pack::QCA400x_WiFi_Driver but everytime i try to build the project I get Error: L6218E: Undefined symbol Driver_SPI0 (referred from cust_spi_hcd.o). I really do not understand the issue there.
