I have referred to the example code provided by the NXP for the mmCAU module, and i'm trying to replicate the same.</P><P>&nbsp;&nbsp;&nbsp;=&gt; I'm trying to use the TDES API provided in the example code. For this i've created a new IAR Build and tried to replicate the way it is done in the example code.</P><P>&nbsp;&nbsp;&nbsp;=&gt; The problem here i face is that the moment i try to execute the 'cau_des_encrypt' API it triggers 'Hard Fault'. Can&nbsp;someone please help me resolve this issue. I have been trying to resolve this since a week.&nbsp;</P><P></P><P>NOTE: I have added the IAR Build.</P></BODY></HTML> Thu, 09 Jan 2020 07:18:48 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Running-DES-ECB-with-mmCAU-on-MKM34Z256VLL7-controller-generates/m-p/989804#M55651 shaiknisar 2020-01-09T07:18:48Z Re: Running DES-ECB with mmCAU on MKM34Z256VLL7 controller generates HardFault upon executing 'cau_des_encrypt' API. https://community.nxp.com/t5/Kinetis-Microcontrollers/Running-DES-ECB-with-mmCAU-on-MKM34Z256VLL7-controller-generates/m-p/989805#M55652 <HTML><HEAD></HEAD><BODY><P>Resolved the Hard fault issue.</P><P>The clock for the mmCAU module wasn't getting enabled.</P></BODY></HTML> Thu, 09 Jan 2020 09:00:56 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Running-DES-ECB-with-mmCAU-on-MKM34Z256VLL7-controller-generates/m-p/989805#M55652 shaiknisar 2020-01-09T09:00:56Z
