https://devzone.nordicsemi.com/f/nordic-q-a/65332/nvs-restrictionsHi , I need to store strings in flash and came across the NVS. I referred to the example in samples/subsys/nvs and was able to do the nvs operation. The following are my observations : (1) the minimum sector_size , i can use is 4096 (2) Maximumen-USTelligent Community 13Fri, 28 Aug 2020 12:29:24 GMThttps://devzone.nordicsemi.com/thread/267004?ContentTypeID=1Fri, 28 Aug 2020 12:29:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c7e1fdc-67f2-4604-a107-bec6f6bd418fSimonr<p>Hi Saravanan</p> <p>1. According to the NVS documentation, the SECTOR_SIZE can be edited as long as you set it to be a multiple of the flash erase page size and a power of 2, so it needs to be a multiple of the page size.&nbsp;</p> <p>2. Is there an error code to the &quot;Usage Fault&quot; error you&#39;re getting. What other byte sizes have you tried when you get this error?</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
