From a9c90a0f8f9080d185233e4037e9c88075366fcb Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Wed, 17 Dec 2014 12:14:32 +0200 Subject: [PATCH] stm32lx: do not attempt mass-erase in-place of first bank erase Commit 832f0a5bfb439 'stm32: add mass erase support for STM32L' added use of mass-erase in-place of bank-erase. This is triggered if first bank is requested to be fully erased. This erroneous action completely fails on STM32L162VEY (has 512 KiB flash in two 256 KiB banks) and also unintently destroying contents of EEPROM and second flash bank.
