smallest part of flash you can erasehttps://devzone.nordicsemi.com/f/nordic-q-a/34244/smallest-part-of-flash-you-can-eraseI want to be sure about erasing flash. Flash is divided into pages and each page has 8 blocks. The smallest amount of flash you can erase is a PAGE. Is this correct. In other words you cannot just erase a block.en-USTelligent Community 13Mon, 14 May 2018 16:49:12 GMTRE: smallest part of flash you can erasehttps://devzone.nordicsemi.com/thread/131932?ContentTypeID=1Mon, 14 May 2018 16:49:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:52a93de4-4b1c-43e6-89ff-4516ac9b4717weightwatcherphil<p>Hi Vidar,</p> <p>this was very helpful.&nbsp; Thank you.</p> <p>Phil</p><div style="clear:both;"></div>RE: smallest part of flash you can erasehttps://devzone.nordicsemi.com/thread/131819?ContentTypeID=1Mon, 14 May 2018 09:03:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e69cfab7-e476-418f-ab65-4dba9c4dec02Vidar Berg<p>Hi,&nbsp;</p> <p>Yes, that is correct, smallest amount you can erase is one flash page (4KB on 52 series).</p> <p>There is support for partial page erase on the 52840, but the page cannot be used until the full page has been fully erased:&nbsp;<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/nvmc.html?cp=2_0_0_3_2_6#concept_partial_erase">http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52840.ps/nvmc.html?cp=2_0_0_3_2_6#concept_partial_erase</a>&nbsp;</p><div style="clear:both;"></div>
