<div class="markdown_content"><p>Make sure you get the pointer value correctly ex: ```</p> <p>pPointer := REF(bTempMem);</p> <p><code>or</code></p> <p>pPointer := REF(bTempMem<span>[0]</span>);</p> <p>```<br/> Idealy put it in a cycling task (online edits may affects memory locations).</p></div>

<div class="markdown_content"><p>I have a unique problem where the code runs fine on a windows soft plc, but gives an access violation on a raspberry pi<br/> There is a large array initialized in a program/function block "bTempMem : ARRAY<span>[0..1000000-1]</span> OF BYTE;"</p> <p>This is used initialize certain arrays by a function block using pointer access to it. It throws an access violation when trying to write to it.<br/> Strangely, if I declare this as a global variable, then i dont get any access violation</p> <p>Any help is appreciated</p></div>
