https://devzone.nordicsemi.com/f/nordic-q-a/21491/jlinkexe-equivalent-of-nrfjprog---erasepageHello, We&#39;re using JLinkExe for production programming. Is there an equivalent of the nrfjprog --erasepage command for JLinkExe? I&#39;m looking for the equivalent of nrfjprog -f nrf52 --erasepage 0x0007F000-0x00080000 It would be cool if nrfjprogen-USTelligent Community 13Fri, 21 Apr 2017 09:03:23 GMThttps://devzone.nordicsemi.com/thread/84325?ContentTypeID=1Fri, 21 Apr 2017 09:03:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7173ecea-d1d1-4808-be6e-eb63d64d9c21bjorn-spockeli<p>Hi Jacob,</p> <p>in order to erase a page on the nRF52 you first have to enable erase mode by writing to the <code>CONFIG</code> register and then write the address of the first word on the flash page to the <code>ERASEPAGE</code> register of the NVMC peripheral, see <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/nvmc.html?cp=2_2_0_10_6_2#register.ERASEPAGE">this</a> section of the nRF52832 Product Specification. Thus, if you want to erase the flash page starting at 0x7F000 you use the following commands</p> <pre><code>w4 4001E504 2 w4 4001E508 0007f000 w4 4001E504 0 </code></pre> <p>The last command sets the program memory access mode to read access only.</p> <p>You also might want to take a look at pynrfjprog, <a href="https://github.com/NordicSemiconductor/pynrfjprog">here</a> is the link to the GitHub repo.</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
