Also some pages will be used for fstorage (peer manager). But you don&#39;t have to worry about this if the size of your code is much lower than the limit.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/113655?ContentTypeID=1Wed, 20 Dec 2017 13:00:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:deeaa5ec-10cd-4fe2-bd3b-a5b7d77e40cfAtlas<p>Hi Hung Thanks. My typo. When use nRF52832-QFAB, what to pay special attention to in the FW code beside the above address?</p> <p>Thanks.

Why do you want to leave the bootloader at 0x38000 ? I assume you are using QFAB 256kB of flash ? In your question you mentioned both QFAA and QFAB. If it&#39;s QFAB , the layout looks fine.</p><div style="clear:both;"></div>
