This is the value you get when using &quot;--family NRF52&quot;.</p> <p>Some devices, such as the nRF52840 and the smaller variant of the nRF52832, have a different amount of Flash memory, and so the start address of the bootloader settings page is different. For that reason there are a number of other possible values for the --family option, such as NRF52840 (0xFF000) and NRF52832QFAB (0x3F000). Make sure to use the correct --family option for your device.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
