It is caused by byte alignment of static uint8_t buffer_memory[(n_blocks) * (block_size)]; in the macro PM_BUFFER_INIT in (pm_buffer.h).en-USTelligent Community 13Wed, 14 Sep 2016 10:51:47 GMThttps://devzone.nordicsemi.com/thread/62830?ContentTypeID=1Wed, 14 Sep 2016 10:51:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ee767fc3-3c12-4121-8e81-c4c7b83355aaSusheel Nuguru<p>Need to force it to 4-bytes word alignment like below in macro <code>PM_BUFFER_INIT-&gt;pm_buffer.h</code></p> <pre><code> __ALIGN(sizeof(uint32_t)) static uint8_t buffer_memory[(n_blocks) * (block_size)]; </code></pre><div style="clear:both;"></div>
