Support of 4-bit ECC for NAND Flashhttps://devzone.nordicsemi.com/f/nordic-q-a/40110/support-of-4-bit-ecc-for-nand-flashHello Nordic community, I am using nRF52840 and try to implement external memory unit for MX35LF2G14AC, which is 2Gb SLC NAND flash. I am wondering nRF52840 can support 4-bit ECC/528B, more precisely whether nRF52840 has enough capability to implementen-USTelligent Community 13Fri, 12 Mar 2021 10:46:16 GMTRE: Support of 4-bit ECC for NAND Flashhttps://devzone.nordicsemi.com/thread/299443?ContentTypeID=1Fri, 12 Mar 2021 10:46:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a632817-849c-404d-8be7-bc64565bceafash007<p>Can we implement in software somehow? <span style="background-color:rgba(255, 255, 255, 1);color:rgba(36, 39, 41, 1);float:none;font-family:Arial, &#39;Helvetica Neue&#39;, Helvetica, sans-serif;font-size:15px;font-style:normal;font-weight:400;letter-spacing:normal;text-align:left;text-indent:0;text-transform:none;white-space:normal;">I have to execute some lightweight error correction codes (ideally BCH) to compare and subsequently correct the mismatches between two binary arrays.
