From 069b746ad9e66ab75973020f992e059c06cf3a7c Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 24 May 2018 21:58:45 +0200 Subject: [PATCH] sf: Enable FSR polling on N25Q256(A) The N25Q256(A) datasheet clearly states that this device does have a Flag Status Register and does update FSR PEC bit 7 during Program and Erase cycles to indicate the cycle is in progress. Enable the FSR PEC bit polling on this device to prevent data corruption.
